契约

新建一个WCF服务类库项目，在其中添加两个WCF服务：GameService，PlayerService

代码如下：


[ServiceContract]
public interface IGameService
{
 [OperationContract]
 Task<string> DoWork(string arg);
}


public class GameService : IGameService
{
 public async Task<string> DoWork(string arg)
 {
  return await Task.FromResult($"Hello {arg}, I am the GameService.");
 }
}


[ServiceContract]
public interface IPlayerService
{
 [OperationContract]
 Task<string> DoWork(string arg);
}


public class PlayerService : IPlayerService
{
 public async Task<string> DoWork(string arg)
 {
  return await Task.FromResult($"Hello {arg}, I am the PlayerService.");
 }
}

服务端

新建一个控制台应用程序，添加一个类 ServiceHostManager


public interface IServiceHostManager : IDisposable
{
 void Start();
 void Stop();
}
public class ServiceHostManager<TService> : IServiceHostManager
 where TService : class
{
 ServiceHost _host;
 public ServiceHostManager()
 {
  _host = new ServiceHost(typeof(TService));
  _host.Opened += (s, a) => {
   Console.WriteLine("WCF监听已启动！{0}", _host.Description.Endpoints[0].Address);
  };
  _host.Closed += (s, a) =>
  {
   Console.WriteLine("WCF服务已终止！{0}", _host.Description.Endpoints[0].Name);
  };   
 }
 public void Start()
 {
  Console.WriteLine("正在开启WCF服务...{0}", _host.Description.Endpoints[0].Name);
  _host.Open();
 }
 public void Stop()
 {
  if (_host != null && _host.State == CommunicationState.Opened)
  {
   Console.WriteLine("正在关闭WCF服务...{0}", _host.Description.Endpoints[0].Name);
   _host.Close();
  }
 }
 public void Dispose()
 {
  Stop();
 }
 public static Task StartNew(CancellationTokenSource cancelTokenSource)
 {
  var theTask = Task.Factory.StartNew(() =>
  {
   IServiceHostManager shs = null;
   try
   {
    shs = new ServiceHostManager<TService>();
    shs.Start();
    while (true)
    {
     if (cancelTokenSource.IsCancellationRequested && shs != null)
     {
      shs.Stop();
      break;
     }
    }
   }
   catch (Exception ex)
   {
    Console.WriteLine(ex);
    if (shs != null)
     shs.Stop();
   }
  }, cancelTokenSource.Token);
  return theTask;
 }
}

在Main方法中启动WCF主机


class Program
 {
  static Program()
  {
   Console.WriteLine("初始化...");
   Console.WriteLine("服务运行期间，请不要关闭窗口。");
   Console.WriteLine();
  }
  static void Main(string[] args)
  {
   Console.Title = "WCF主机 x64.（按 [Esc] 键停止服务）";
   var cancelTokenSource = new CancellationTokenSource();
   ServiceHostManager<WcfContract.Services.GameService>.StartNew(cancelTokenSource);
   ServiceHostManager<WcfContract.Services.PlayerService>.StartNew(cancelTokenSource);
   while (true)
   {
    if (Console.ReadKey().Key == ConsoleKey.Escape)
    {
     Console.WriteLine();
     cancelTokenSource.Cancel();
     break;
    }
   }
   Console.ReadLine();
  }
 }

服务端配置

在控制台应用程序的App.config中配置system.serviceModel


<system.serviceModel>
 <services>
  <service name="Wettery.WcfContract.Services.GameService" behaviorConfiguration="gameMetadataBehavior">
  <endpoint address="net.tcp://localhost:19998/Wettery/GameService" binding="netTcpBinding" contract="Wettery.WcfContract.Services.IGameService" bindingConfiguration="netTcpBindingConfig">
   <identity>
   <dns value="localhost" />
   </identity>
  </endpoint>
  </service>
  <service name="Wettery.WcfContract.Services.PlayerService" behaviorConfiguration="playerMetadataBehavior">
  <endpoint address="net.tcp://localhost:19998/Wettery/PlayerService" binding="netTcpBinding" contract="Wettery.WcfContract.Services.IPlayerService" bindingConfiguration="netTcpBindingConfig">
   <identity>
   <dns value="localhost" />
   </identity>
  </endpoint>
  </service>
 </services>
 <bindings>
  <netTcpBinding>
  <binding name="netTcpBindingConfig" closeTimeout="00:30:00" openTimeout="00:30:00" receiveTimeout="00:30:00" sendTimeout="00:30:00" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="100" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxConnections="100" maxReceivedMessageSize="2147483647">
   <readerQuotas maxDepth="64" maxStringContentLength="2147483647" maxArrayLength="2147483647 " maxBytesPerRead="4096" maxNameTableCharCount="16384" />
   <reliableSession ordered="true" inactivityTimeout="00:30:00" enabled="false" />
   <security mode="Transport">
   <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
   </security>
  </binding>
  </netTcpBinding>
 </bindings>
 <behaviors>
  <serviceBehaviors>
  <behavior name="gameMetadataBehavior">
   <serviceMetadata httpGetEnabled="True" httpGetUrl="http://localhost:8081/Wettery/GameService/MetaData" />
   <serviceDebug includeExceptionDetailInFaults="True" />
   <serviceThrottling maxConcurrentCalls="1000" maxConcurrentInstances="1000" maxConcurrentSessions="1000" />
  </behavior>
  <behavior name="playerMetadataBehavior">
   <serviceMetadata httpGetEnabled="True" httpGetUrl="http://localhost:8081/Wettery/PlayerService/MetaData" />
   <serviceDebug includeExceptionDetailInFaults="True" />
   <serviceThrottling maxConcurrentCalls="1000" maxConcurrentInstances="1000" maxConcurrentSessions="1000" />
  </behavior>
  </serviceBehaviors>
 </behaviors>
 </system.serviceModel>

未避免元数据泄露，部署时将HttpGetEnable设为False

运行控制台应用程序

按[ESC]键终止服务
