几个WCF源码示例

WCF_PRACTICE.rar

以下插入(其中一个程序的)一些关键代码示例：

服务端：

定义接口

namespace MathServiceLibrary
{
    [ServiceContract]
    public interface IBasicMath
    {
        [OperationContract]
        int Add(int x, int y);
    }
}

继承接口

namespace MathServiceLibrary
{
  public class MathService : IBasicMath
  {
    public int Add(int x, int y)
    {
      // To simulate a lengthy request. 
      System.Threading.Thread.Sleep(5000);
      return x + y;
    }
  }
}

using System.ServiceProcess;
using System.Text;

// Be sure to import these namespaces:
using MathServiceLibrary;
using System.ServiceModel;

namespace MathWindowsServiceHost
{
    public partial class MathWinService : ServiceBase
    {
        // A member variable of type ServiceHost.
        private ServiceHost myHost;

        public MathWinService()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
            if (myHost != null)
            {
                myHost.Close();
            }

            // Create the host and specify a URL for an HTTP binding.
            myHost = new ServiceHost(typeof(MathService), 
                new Uri("http://localhost:8080/MathServiceLibrary"));
            myHost.AddDefaultEndpoints();

            // Open the host.
            myHost.Open();
        }

        protected override void OnStop()
        {
            // Shut down the host.
            if (myHost != null)
                myHost.Close();
        }
    }
}

客户端：

using System;
using MathClient.ServiceReference;
using System.Threading;

namespace MathClient
{
    class Program
    {
        /* 在运行中，安装Windows服务的方法：
             //在运行中，将当前目录转向MathWindowsServiceHost.exe所在的目录，(盘符直接切换, cd 切换文件夹)
            //然后输入 F:\Windows\Microsoft.NET\Framework\v2.0.50727\InstallUtil.exe MathWindowsServiceHost.exe
            // 或F:\Windows\Microsoft.NET\Framework\v4.0.30319\IntallUtil.exe MathWindowsServiceHost.exe(本程序选4.0的)
            //则在服务中可以看到新增了一项服务

            //另外，删除服务的方法如下：
            //在运行中，将当前目录转向MathWindowsServiceHost.exe所在的目录，
            //sc delete MathWindowsServiceHost （MathWindowsServiceHost为当前要删除的服务名）,即可删除该服务
         
         */

        static void Main(string[] args)
        {
            Console.WriteLine("***** The Async Math Client *****\n");

            using (BasicMathClient proxy = new BasicMathClient())
            {
                proxy.Open();

                // Add numbers in an async manner, using lambda expression
                IAsyncResult result = proxy.BeginAdd(2, 3,
                  ar =>
                  {
                      Console.WriteLine("2 + 3 = {0}", proxy.EndAdd(ar));
                  }, null);

                while (!result.IsCompleted)
                {
                    Thread.Sleep(200);
                    Console.WriteLine("Client working...");
                }
            }
            Console.ReadLine();
        }
    }
}
