经常安装PC端的应用，特别是重装系统之后，大致分为两类。一类像QQ，搜狗输入法这样的。分三步走的：第一个页面可以自定义安装路径和软件许可。第二个页面显示安装进度条，第三个页面推荐其他应用。先不管人家怎么实现的，我们先回顾一下。
QQ:
再一个就是分六步或七步走的，如QQ影音：欢迎界面，用户许可，安装组件，安装目录，安装进度，安装完成，有七步的，一般会多一些软件推荐。当然还有其他的，比如是基于ClickOnce打包的，就一个界面，一个进度条。没有安装目录选择，这一般不是商业软件。先说第二种，上一步下一步的有很多第三方的打包工具，比较有名的有InstallShield,setupfactory等，看似有了图形化的操作界面，做简单的还可以，但是要是有一些自定义的部分就比较麻烦，因为你没地方改，比如你要在一个安装包中去静默的触发另一个安装包悄悄的安装，而且这些还是商业化的。开源的WIX，基于XML文件配置的方法来打包应用。Wix的基本打包(6,7个步骤)，可以出门左拐可以看我之前的教程。接下来要说的，是基于WIX的Bootstrapper工程用WPF接入安装界面。
WIX是基于BootstrapperCore.dll提供UI扩展的，你可以使用WPF，也可以使用Winform作为安装界面。而这里先不得不先说其中的两个对象。一个是Engine，它提供了最根本的安装方法，如Detect,Plan,Apply和Quit等，另外一个就是引导对象BootstrapperApplication，他提供了安装相关事件，设置窗体对象等。这为我们自定义界面的时候控制安装包提供了基础。
一、工程准备
1）新建一个Bootstrapper工程。
新建完成之后会有一个Bundle.wxs文件，里面包含你要安装的msi文件和依赖组件比如.net4.0.
<?xml version="1.0" encoding="UTF-8"?> <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:bal="http://schemas.microsoft.com/wix/BalExtension" xmlns:netfx="http://schemas.microsoft.com/wix/NetFxExtension" xmlns:util="http://schemas.microsoft.com/wix/UtilExtension"> <Bundle Name="WIXTest" Version="1.1.1.0" Manufacturer="Delta" UpgradeCode="{51C1EB78-C0D2-4C30-803C-8D7993CB38A5}" Compressed="yes" > <BootstrapperApplicationRef Id="WixStandardBootstrapperApplication.RtfLicense" /> <WixVariable Id="WixMbaPrereqLicenseUrl" Value=""/> <WixVariable Id="WixMbaPrereqPackageId" Value=""/> <Chain DisableRollback='yes'> <PackageGroupRef Id="Netfx4Full" /> <MsiPackage Id="DIAView" SourceFile="D:TestWixinDebugzh-cnTestWix.msi" Compressed="yes" DisplayInternalUI="yes" > </MsiPackage> </Chain> </Bundle> <Fragment> <util:RegistrySearchRef Id="NETFRAMEWORK40"/> <PackageGroup Id="Netfx4Full"> <ExePackage Id="Netfx4FullExe" Cache="no" Compressed="yes" PerMachine="yes" Permanent="yes" Vital="yes" SourceFile="$(var.Dia)dotNetFx40_Full_x86_x64.exe" InstallCommand="/q /norestart " DetectCondition="NETFRAMEWORK40" DownloadUrl="http://go.microsoft.com/fwlink/?LinkId=164193"/> </PackageGroup> </Fragment> </Wix>
最终的EXE还是通过这个工程来生成的。MsiPackage的ID 后面可以用来检测当前电脑是否安装了这个软件。
二、创建WPF界面程序。
1).创建一个C# Library工程CustomBA，引用BootstrapperCore.dll 及 WPF相关dll
BootstrapperCore在你安装的wix安装目录中就能找到。比如我使用的wix3.8,路径就是C:Program Files (x86)WiX Toolset v3.8SDKBootstrapperCore.dll
另外一个就是Prism 组件，这个可以通过Nuget安装。
但这个有点嫌多，其实工程只使用到了属性更改通知和命令。可以使用wix源码中的两个对象。如此就不必引用上面的Prism
RelayCommand
public class RelayCommand : ICommand { private readonly Action<object> execute; private readonly Predicate<object> canExecute; public RelayCommand(Action<object> execute) : this(execute, null) { } public RelayCommand(Action<object> execute, Predicate<object> canExecute) { this.execute = execute; this.canExecute = canExecute; } public event EventHandler CanExecuteChanged { add { CommandManager.RequerySuggested += value; } remove { CommandManager.RequerySuggested -= value; } } [DebuggerStepThrough] public bool CanExecute(object parameter) { return this.canExecute == null ? true : this.canExecute(parameter); } public void Execute(object parameter) { this.execute(parameter); } }
PropertyNotifyBase
public abstract class PropertyNotifyBase : INotifyPropertyChanged { /// <summary> /// Initializes a new instance of the <see cref="PropertyNotifyBase"/> class. /// </summary> protected PropertyNotifyBase() { } /// <summary> /// Raised when a property on this object has a new value. /// </summary> public event PropertyChangedEventHandler PropertyChanged; /// <summary> /// Warns the developer if this object does not have a public property with the /// specified name. This method does not exist in a Release build. /// </summary> /// <param name="propertyName">Property name to verify.</param> [Conditional("DEBUG")] [DebuggerStepThrough] public void VerifyPropertyName(string propertyName) { // Verify that the property name matches a real, public, instance property // on this object. if (null == TypeDescriptor.GetProperties(this)[propertyName]) { Debug.Fail(String.Concat("Invalid property name: ", propertyName)); } } /// <summary> /// Raises this object's PropertyChanged event. /// </summary> /// <param name="propertyName">The property that has a new value.</param> protected virtual void OnPropertyChanged(string propertyName) { this.VerifyPropertyName(propertyName); PropertyChangedEventHandler handler = this.PropertyChanged; if (null != handler) { PropertyChangedEventArgs e = new PropertyChangedEventArgs(propertyName); handler(this, e); } } }
使用方法差别不大。
2）可以建立如下的文件目录，配合WPF的MVVM。
3）增加配置文件，以让Burn使用新的程序集。必须命名为BootstrapperCore.config ，也可以从C:Program Files (x86)WiX Toolset v3.8SDK 目录下拷贝一个版本。
<?xml version="1.0" encoding="utf-8" ?> <!-- <copyright file="BootstrapperCore.config" company="Outercurve Foundation"> Copyright (c) 2004, Outercurve Foundation. This software is released under Microsoft Reciprocal License (MS-RL). The license and further copyright text can be found in the file LICENSE.TXT at the root directory of the distribution. </copyright> --> <configuration> <configSections> <sectionGroup name="wix.bootstrapper" type="Microsoft.Tools.WindowsInstallerXml.Bootstrapper.BootstrapperSectionGroup, BootstrapperCore"> <section name="host" type="Microsoft.Tools.WindowsInstallerXml.Bootstrapper.HostSection, BootstrapperCore" /> </sectionGroup> </configSections> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0" /> <supportedRuntime version="v2.0.50727" /> </startup> <wix.bootstrapper> <!-- Example only. Use only if the startup/supportedRuntime above cannot discern supported frameworks. --> <!-- <supportedFramework version="v4Client" /> <supportedFramework version="v3.5" /> <supportedFramework version="v3.0" /> --> <!-- Example only. Replace the host/@assemblyName attribute with assembly that implements BootstrapperApplication. --> <host assemblyName="AssemblyWithClassThatInheritsFromBootstrapperApplication" /> </wix.bootstrapper> </configuration>
修改为：
<?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="wix.bootstrapper" type="Microsoft.Tools.WindowsInstallerXml.Bootstrapper.BootstrapperSectionGroup, BootstrapperCore"> <section name="host" type="Microsoft.Tools.WindowsInstallerXml.Bootstrapper.HostSection, BootstrapperCore" /> </sectionGroup> </configSections> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0" /> </startup> <wix.bootstrapper> <host assemblyName="CustomBA"> <supportedFramework version="v4Full" /> <supportedFramework version="v4Client" /> </host> </wix.bootstrapper> </configuration>
CustomBA.dll，BootstrapperCore.config 和 Microsoft.Practices. Prism.dll(如果使用了) 都会拷贝到bootstrapper项目中去。
4）修改Assemblyinfo
增加：
[assembly: BootstrapperApplication(typeof(CustomBootstrapperApplication))] [assembly: AssemblyTitle("CustomBA")]
CustomBootstrapperApplication 是我们接下来要创建的一个对象，Bundle会调用它的Run方法，这是整个安装包的起点。
5）创建WPF对象。
根据MVVM模式，我们分别创建Model，ViewModel和View 以及一些辅助的对象。
1.Model-->BootstrapperApplicationModel
public class BootstrapperApplicationModel { private IntPtr hwnd; public BootstrapperApplicationModel( BootstrapperApplication bootstrapperApplication) { BootstrapperApplication = bootstrapperApplication; hwnd = IntPtr.Zero; } public BootstrapperApplication BootstrapperApplication { get; private set; } public int FinalResult { get; set; } public void SetWindowHandle(Window view) { hwnd = new WindowInteropHelper(view).Handle; } public void PlanAction(LaunchAction action) { BootstrapperApplication.Engine.Plan(action); } public void ApplyAction() { BootstrapperApplication.Engine.Apply(hwnd); } public void LogMessage(string message) { BootstrapperApplication.Engine.Log(LogLevel.Standard, message); } public void SetBurnVariable(string variableName, string value) { BootstrapperApplication.Engine.StringVariables[variableName] = value; } }
从代码看是包装了Engine的方法，设置窗口，PlanAction，ApplyAction，LogMessage以及设置变量等。
PlanAction是做一个任务准备，例如安装，卸载，修复或者更改。而ApplyAction就是执行这个任务。当UI上的按钮点击时，我们调用PlanAction方法，传递我们要执行的任务。Plan完成之后，再会触发ApplyAction。最后一点就是FinalResult 属性。我们用来存储引导程序结束后Burn引擎返回的状态码 。
2.ViewModel-->InstallViewModel
这是一个重要的交互对象。InstallState 安装状态，UpdateState 更新状态，Command用来处理用户在安装界面的操作，在构造函数里进行初始化。然后就是事件订阅。
using System; using System.Collections.Generic; using System.Diagnostics; using System.Reflection; using System.Windows; using System.Windows.Input; using Microsoft.Tools.WindowsInstallerXml.Bootstrapper; namespace CustomBA.ViewModels { public class InstallViewModel : PropertyNotifyBase { public enum InstallState { Initializing, Present, NotPresent, Applying, Cancelled, Applied, Failed, } public enum UpdateState { Unknown, Initializing, Checking, Current, Available, Failed, } /// <summary> /// 记录状态 /// </summary> private InstallState state; public UpdateState updatestate; /// <summary> /// 需要显示在WPFWindow /// </summary> private string message; private BootstrapperApplicationModel model; private string _packageId = string.Empty; private bool canceled; private Dictionary<string, int> executingPackageOrderIndex; private string username; private int progress; private int cacheProgress; private int executeProgress; private Version _version = new Version("2.0.0.0"); private bool _installEnabled; private int progressPhases=1; private bool isUnstalling=false; #region Command /// <summary> /// 执行安装命令 /// </summary> public ICommand InstallCommand { get; private set; } public ICommand UninstallCommand { get; private set; } public ICommand CancelCommand { get; private set; } public ICommand LaunchNewsCommand { get; private set; } private ICommand repairCommand; public ICommand RepairCommand { get { return this.repairCommand ?? (this.repairCommand = new RelayCommand(param => model.PlanAction(LaunchAction.Repair) , param => State == InstallState.Present)); } } #endregion #region 属性 public string Message { get { return message; } set { if (message != value) { message = value; OnPropertyChanged("Message"); } } } public InstallState State { get { return state; } set { if (state != value) { state = value; Message = "Status: " + state; OnPropertyChanged("State"); Refresh(); } } } public string PackageId { get { return _packageId; } set { if (_packageId != value) { _packageId = "packid:" + value; OnPropertyChanged("PackageId"); } } } public bool Canceled { get { return this.canceled; } set { if (this.canceled != value) { this.canceled = value; OnPropertyChanged("Canceled"); } } } public Version Version { get { return _version; } } public string Username { get { return this.username; } set { this.username = value; this.model.SetBurnVariable("Username", this.username); } } public int Progress { get { if (isUnstalling) { return progress*2; } return this.progress; } set { this.progress = value; OnPropertyChanged("Progress"); OnPropertyChanged("Persent"); } } private string _info; public string Info { get { if(string.IsNullOrEmpty(_info)) _info= InstallEnabled ?

在构造函数内部，WireUpEventHandlers方法里面的事件订阅处理的是安装的状态。其他就是处理安装进度。安装进度是由两部分组成的，CacheAcquireProgress 和ExecuteProgress，基于二者完成的进度平均得到当前的安装进度。Wix3.6书中的代码如下：
this.model.BootstrapperApplication.CacheAcquireProgress += (sender, args) => { this.cacheProgress = args.OverallPercentage; this.Progress = (this.cacheProgress + this.executeProgress) / 2; }; this.model.BootstrapperApplication.ExecuteProgress += (sender, args) => { this.executeProgress = args.OverallPercentage; this.Progress = (this.cacheProgress + this.executeProgress) / 2; };
我按照wix3.8中WixBA的源码调整了下。卸载的时候常数是1而不是2.
3.在Views中新建一个InstallView.Xaml 。
我们先做一个简单的。只有几个按钮。最后的界面如下(美观度先不考虑，;-))： 只有安装，卸载和取消三个按钮，再加一个进度条和一个消息提示。
XAML：
<Grid> <StackPanel> <Label Content="{Binding Message}" /> <Button Command="{Binding InstallCommand}">Install</Button> <Button Command="{Binding UninstallCommand}">Uninstall</Button> <Button Command="{Binding CancelCommand}">Cancel</Button> <Label VerticalAlignment="Center">Progress:</Label> <Label Content="{Binding Progress}" /> <ProgressBar Width="200" Height="30" Value="{Binding Progress}" Minimum="0" Maximum="100" /> </StackPanel> </Grid>
CS:
public InstallView(InstallViewModel viewModel) { this.InitializeComponent(); this.DataContext = viewModel; this.Closed += (sender, e) => viewModel.CancelCommand.Execute(this); }
4.入口对象CustomBootstrapperApplication。
public class CustomBootstrapperApplication:BootstrapperApplication { public static Dispatcher Dispatcher { get; set; } static public DiaViewModel Model { get; private set; } static public InstallView View { get; private set; } protected override void Run() { Model = new DiaViewModel(this); Dispatcher = Dispatcher.CurrentDispatcher; var model = new BootstrapperApplicationModel(this); var viewModel = new InstallViewModel(model); View = new InstallView(viewModel); model.SetWindowHandle(View); this.Engine.Detect(); View.Show(); Dispatcher.Run(); this.Engine.Quit(model.FinalResult); } }
重载了Run方法，是UI的主要入口函数，它会被Burn引擎调用，Dispatcher 用于UI和后台线程直接通信。它提供了Invoke方法，我们可以用来更新UI控件的状态。而这里的Model相当于一个辅助对象。
public class DiaViewModel { private Version _version; private const string BurnBundleInstallDirectoryVariable = "InstallFolder"; private const string BurnBundleLayoutDirectoryVariable = "WixBundleLayoutDirectory"; public DiaViewModel(BootstrapperApplication bootstrapper) { Bootstrapper = bootstrapper; Telemetry = new List<KeyValuePair<string, string>>(); } /// <summary> /// Gets the bootstrapper. /// </summary> public BootstrapperApplication Bootstrapper { get; private set; } /// <summary> /// Gets the bootstrapper command-line. /// </summary> public Command Command { get { return Bootstrapper.Command; } } /// <summary> /// Gets the bootstrapper engine. /// </summary> public Engine Engine { get { return Bootstrapper.Engine; } } /// <summary> /// Gets the key/value pairs used in telemetry. /// </summary> public List<KeyValuePair<string, string>> Telemetry { get; private set; } /// <summary> /// Get or set the final result of the installation. /// </summary> public int Result { get; set; } /// <summary> /// Get the version of the install. /// </summary> public Version Version { get { if (null == _version) { Assembly assembly = Assembly.GetExecutingAssembly(); FileVersionInfo fileVersion = FileVersionInfo.GetVersionInfo(assembly.Location); _version = new Version(fileVersion.FileVersion); } return _version; } } /// <summary> /// Get or set the path where the bundle is installed. /// </summary> public string InstallDirectory { get { if (!Engine.StringVariables.Contains(BurnBundleInstallDirectoryVariable)) { return null; } return Engine.StringVariables[BurnBundleInstallDirectoryVariable]; } set { Engine.StringVariables[BurnBundleInstallDirectoryVariable] = value; } } /// <summary> /// Get or set the path for the layout to be created. /// </summary> public string LayoutDirectory { get { if (!Engine.StringVariables.Contains(BurnBundleLayoutDirectoryVariable)) { return null; } return Engine.StringVariables[BurnBundleLayoutDirectoryVariable]; } set { Engine.StringVariables[BurnBundleLayoutDirectoryVariable] = value; } } public LaunchAction PlannedAction { get; set; } /// <summary> /// Creates a correctly configured HTTP web request. /// </summary> /// <param name="uri">URI to connect to.</param> /// <returns>Correctly configured HTTP web request.</returns> public HttpWebRequest CreateWebRequest(string uri) { var request = (HttpWebRequest)WebRequest.Create(uri); request.UserAgent = String.Concat("WixInstall", Version.ToString()); return request; } }
model.SetWindowHandle(view);
这个方法会控制wpf窗口，在Burn 引擎安装或卸载的时候会用到。
this.Engine.Detect();
它会让Burn去检查是否bundle已经安装，这样当窗口显示出来的时候，我们需要知道是显示一个安装按钮还是一个卸载按钮。show方法会显示WPF窗口，接着我们调用了
Dispatcher.Run()
它会一直执行到Dispatcher关闭或遇到任务取消，关闭窗口我们可以调用Dispatcher的InvokeShutdown方法。
Engine.Quit
会优雅的退出bootstrapper 进程。而不是直接kill。
5.更改配置
以上wpf这边就是已经准备好，现在就需要告诉Bootstrapper工程。
首先我们需要引用CustomBA这个工程，以及相关的dll
然后修改Bundle中的BootstrapperApplicationRef，使用payload相当于是把CustomBA下面的DLL都copy过来。但如果没有使用prism，就可以将其全部拿掉。
<BootstrapperApplicationRef Id="ManagedBootstrapperApplicationHost"> <Payload SourceFile="$(var.CustomBA.TargetDir)CustomBA.dll" /> <Payload SourceFile="$(var.CustomBA.TargetDir)BootstrapperCore.config" /> <Payload SourceFile="$(var.CustomBA.TargetDir)Microsoft.Practices.Prism.Composition.dll" /> <Payload SourceFile="$(var.CustomBA.TargetDir)Microsoft.Practices.Prism.Interactivity.dll" /> <Payload SourceFile="$(var.CustomBA.TargetDir)Microsoft.Practices.Prism.Mvvm.Desktop.dll" /> <Payload SourceFile="$(var.CustomBA.TargetDir)Microsoft.Practices.Prism.Mvvm.dll" /> <Payload SourceFile="$(var.CustomBA.TargetDir)Microsoft.Practices.Prism.PubSubEvents.dll" /> <Payload SourceFile="$(var.CustomBA.TargetDir)Microsoft.Practices.Prism.SharedInterfaces.dll" /> <Payload SourceFile="$(var.CustomBA.TargetDir)Microsoft.Practices.ServiceLocation.dll" /> </BootstrapperApplicationRef>
然后再编译运行，就ok了。 运行一下安装包，wpf界面出来，有点小激动，比起xml配置的界面还是要好多了，主要是给了各种可能。
三、界面优化
当然，上面的界面还不能满足我们的胃口，我就先把WIXBA的界面抓过来了。
修改了下安装界面。明白了安装步骤和事件控制，怎么折腾界面那都是你自己的事情了。这个界面也不是很好，进度条不显示的时候纠结显示些别的什么。
安装前： 卸载中：

小结: 以上就是整个过程，基本走通了，但还没有达到最终目的。要制作想QQ那样三步的安装界面，还有2个关键比较重要的问题没有解决。
1.使用了wpf界面后，bundle无法再先安装.net . 这意味着要在我们的wpf界面之前安装.net(不然wpf界面跑不起来)，用wix3.9编译，会给出提示界面。但安装.net失败。
2.用户选择路径问题，原本我们是通过msi的安装界面来让用户选择安装路径，但现在msi的安装界面就显得有些多余。但这是两个工程，如何把安装界面传递过去。也是个问题。
这两个问题解决后，我会在后面的博客中更新。那样才算完整。
需要的demo的留邮箱，觉得可以的就点个赞~
