WPF最简单的窗体实现,对比WinForm

.net framework3.0 引入了WPF,WCF,WWF,CardSpace等新的类库,本身还是需要CLR2.0
对WinForm想必学员都已经很清楚,就是从System.Forms空间下的Application的静态方法Run传递一个Form类对象实例就OK了.关键代码如下:

System.Windows.Forms.Application.Run(new System.Windows.Forms.Form())

编译方法：

csc /t:winexe SimpleWinForm.cs

/**//*--===------------------------------------------===---
 * 最简单的WinForm: 
 *      Application.Run( new System.Windows.Forms.Form())
 * --===------------------------------------------===---*/

using System.Windows.Forms;

namespace Chapter01
{
    public class SimpleWinform : Form
    {
        public SimpleWinform()
        {
            this.Text = "手工创建的WinForm窗体.";
            this.Opacity = .5;
        }
    }

    public class RunSimpleWinform
    {
        public static void Main_SimpleWinform()
        {
            //Application.Run(new Form());
            Application.Run(new SimpleWinform());
        }
    }
}

WPF窗体必须引用4个类库:PresentationCore, PresentationFramework, System, WindowsBase,然后会发现Forms命名空间下面多了Windows类,这就是WPF的窗体对象. 编译完成后可以用reflector对生成的执行文件反编译，参照reference就可以知道引用了那些dll库。

编译方法：

csc /t:winexe SimpleWPFWindow.cs /r:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.0\PresentationFramework.dll" /R:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.0\WindowsBase.dll" /R:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.0\PresentationCore.dll"

/**//*--===------------------------------------------===---
 * WPF实现示例:
 * 引入类库:PresentationCore, PresentationFramework,WindowsBase,
 * --===------------------------------------------===---*/
using System;
using System.Windows;

namespace Chapter01
{
    class WPF_Window
    {
        [STAThread]
        public static void Main()
        {
            System.Windows.Window window = new Window();
            window.Title = "手工实现的WPF窗体";
            window.Show();

            Application application = new Application();
            application.Run();
        }
    }
}

WPF桌面窗体和WinForm对比:
        WPF通过在System.Windows命名空间下面加新类Window和Application分别实现窗体和程序线程;
            System.Windows.Window window = new Window();
            System.Windows.Application application = new Application();

        而Winform通过.net2.0提供的System.Windows.Forms命名空间下的Form类实现.
       System.Windows.Forms.Application.Run(new System.Windows.Forms.Form());
