WCF 承载服务
WinForm 承载 WCF
服务端
服务代码
服务接口：
namespace WCFService
{
[ServiceContract]
public interface IServiceWindow
{
[OperationContract(IsOneWay=false)]
string GetCurrentTime();
}
}
服务实现：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
namespace WCFService
{
public class ServiceWindow:IServiceWindow
{
#region IServiceWindow 成员
public string GetCurrentTime()
{
return string.Format("Window Server Time:{0}", DateTime.Now.ToString());
}
#endregion
}
}
配置
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<services>
 |
<service behaviorConfiguration="WCFService.ServiceWindowBehavior"
name="WCFService.ServiceWindow">
<host>
<baseAddresses>
<add baseAddress="http://localhost:8000/ServiceWindow/"/>
</baseAddresses>
</host>
<endpoint address="/Address1"
binding="basicHttpBinding"
contract="WCFService.IServiceWindow"/>
<endpoint address="mex"
binding="mexHttpBinding"
contract="IMetadataExchange" />
</service>
</services >
<behaviors>
<serviceBehaviors>
<behavior name="WCFService.ServiceWindowBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
启动代码
public void Start()
{
ServiceHost host = new ServiceHost(typeof(ServiceWindow));
host.Open();
}
private void btnStart_Click(object sender, EventArgs e)
{
Start();
}
客户端
如何调用
1. 启动服务窗体
2. 客户端添加服务引用
调用代码
ServiceWindow.ServiceWindowClient myHost3 = new WCFTest.ServiceWindow.ServiceWindowClient();
Console.WriteLine( myHost3.GetCurrentTime());
结果：
IIS 承载 WCF（略）

Windows Service 承载 WCF

using System.Runtime.Serialization;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
namespace WindowsService

ServiceBase 类继承来实现 Windows 服务代码
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.ServiceModel;
namespace WindowsService
{
public partial class ServiceTestWindowService : ServiceBase
{
private ServiceHost serviceHost = null;
public ServiceTestWindowService()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
if (serviceHost != null)
{
serviceHost.Close();
}
serviceHost = new ServiceHost(typeof(ServiceTest));
serviceHost.Open();
}
protected override void OnStop()
{
if(serviceHost!=null)
{
serviceHost.Close();
serviceHost = null;
}
}
}
}
Installer 继承类 实现服务安装服务
using System;
using System.Collections;
using System.Collections.Generic;
using System.ComponentModel;
using System.Configuration.Install;
using System.Linq;
using System.ServiceProcess;
namespace WindowsService
{
[RunInstaller(true)]
public partial class Installer1 : Installer
{
private ServiceProcessInstaller process;
private ServiceInstaller service;
public Installer1()
{
InitializeComponent();
process = new ServiceProcessInstaller();
process.Account = ServiceAccount.LocalSystem;
service = new ServiceInstaller();
service.ServiceName = "WCFWindowsServiceSample";
Installers.Add(process);
Installers.Add(service);
}
}
}
配置代码
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>

如何调ServiceWindowService.ServiceTestClient testClient = new WCFTest.ServiceWindowService.ServiceTestClient();
Console.WriteLine(testClient.GetCurrentTime());用
l 补充说明：
ServiceHost 不一定必须在在windows 服务的 OnStart中实现。OnStart
下面例子演示了这种实现。
