化零为整WCF(5) - 宿主Hosting(宿主在IIS, Application, WAS, Window


		作者：webabcd

介绍
WCF(Windows Communication Foundation) - 宿主(Hosting)：WCF服务可以宿主在IIS, Application, WAS, WindowsService。本文以宿主在WindowsService为例。

示例
1、服务
IHello.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
namespace WCF.ServiceLib.Sample
{
    /**//// <summary>
    /// IHello接口
    /// </summary>
    [ServiceContract]
    public interface IHello
    {
        /**//// <summary>
        /// 打招呼方法
        /// </summary>
        /// <param name="name">人名</param>
        /// <returns></returns>
        [OperationContract]
        string SayHello(string name);
    }
}
Hello.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
namespace WCF.ServiceLib.Sample
{
    /**//// <summary>
    /// Hello类
    /// </summary>
    public class Hello : IHello
    {
        /**//// <summary>
        /// 打招呼方法
        /// </summary>
        /// <param name="name">人名</param>
        /// <returns></returns>
        public string SayHello(string name)
        {
            return "Hello: " + name;
        }
    }
}

2、宿主
Hello.cs(WindowsService)
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel;
using System.Configuration;
using System.Configuration.Install;
using System.ServiceModel;
using System.ServiceProcess;
namespace WCF.ServiceHostByWindowsService.Sample
{
    /**//// <summary>
    /// 初始化 System.Configuration.Install.Installer 类的新实例。
    /// </summary>
    [RunInstaller(true)]
    public class ProjectInstaller : Installer
    {
        private ServiceProcessInstaller process;
        private ServiceInstaller service;
        /**//// <summary>
        /// 构造函数
        /// </summary>
        public ProjectInstaller()
        {
            process = new ServiceProcessInstaller();
            process.Account = ServiceAccount.LocalSystem;
            service = new ServiceInstaller();
            service.ServiceName = "WCF.ServiceHostByWindowsService";
            service.Description = "WCF服务宿主在WindowsService[webabcd测试用]";
            base.Installers.Add(process);
            base.Installers.Add(service);
        }
    }
    /**//// <summary>
    /// Windows服务类
    /// </summary>
    public class WindowsService : ServiceBase
    {
        public ServiceHost serviceHost = null;
        /**//// <summary>
        /// 主函数
        /// </summary>
        public static void Main()
        {
            ServiceBase.Run(new WindowsService());
        }
        /**//// <summary>
        /// 构造函数
        /// </summary>
        public WindowsService()
        {
            base.ServiceName = "WCF.ServiceHostByWindowsService";
        }
        /**//// <summary>
        /// 启动Windows服务
        /// </summary>
        /// <param name="args">args</param>
        protected override void OnStart(string[] args)
        {
            if (serviceHost != null)
            {
                serviceHost.Close();
            }
            // 为WCF.ServiceLib.Sample.Hello创建ServiceHost
            serviceHost = new ServiceHost(typeof(WCF.ServiceLib.Sample.Hello));
            serviceHost.Open();
            ServiceHost的几个事件（顾名思义）#region ServiceHost的几个事件（顾名思义）
            /**//*
            serviceHost.Opening += 
            serviceHost.Opened += 
            serviceHost.Closing += 
            serviceHost.Faulted += 
            serviceHost.UnknownMessageReceived += 
             */
            #endregion
        }
        /**//// <summary>
        /// 停止Windows服务
        /// </summary>
        protected override void OnStop()
        {
