如何在wcf中用net tcp协议进行通讯，一个打开Wcf的公共类。比较好好，可以记下来。配置文件中注意配置 Service,binding,behaviors. Service中配置endpoint 指明abc ,binding中配置tcp通讯的要关参数，behaivor中配置http请求的地址

1.建立服务服务端

还是用上次的代码，提供一个user类，实现一个方法

[ServiceContract]
 public interface IUser
 {
 [OperationContract]
 string GetUserInfo();
 }
[ServiceContract]
 public interface IUser
 {
 [OperationContract]
 string GetUserInfo();
 }

2.ServiceHostManager公有类

通过公有类可以减少代码编写量，可以保存下来，以后用的时候直接拿来用

public interface IServiceHostmanager : IDisposable
 {
 void Start();
 void Stop();
 }

 public class ServiceHostManager<TService>:IServiceHostmanager 
 where TService:class
 {
 private ServiceHost host;
 public void Dispose()
 {
  Stop();
 }

 public ServiceHostManager()
 {
  host=new ServiceHost(typeof(User));
  host.Opened+= (sender, e) =>
  {
  Console.WriteLine("wcf服务已经启动监听{0}",host.Description.Endpoints[0].Address);
  };
  host.Closed+= (sender, e) =>
  {
  Console.WriteLine("wcf服务已经启动关闭{0}", host.Description.Endpoints[0].Address);
  };
 } 
 public void Start()
 {
  Console.WriteLine("正在启动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 static Task StartNew(CancellationTokenSource conTokenSource)
 {
  var task = Task.Factory.StartNew(() =>
  {
  IServiceHostmanager shm = null;
  try
  {
   shm = new ServiceHostManager<TService>();
   shm.Start();
   while (true)
   {
   if (conTokenSource.IsCancellationRequested && shm != null)
   {
    shm.Stop();
    break;
   }
   }
  }
  catch (Exception ex)
  {
   Console.WriteLine(ex.Message);
   if (shm != null) shm.Stop();
  }
  },conTokenSource.Token);
  return task;
 }
 }

3.配置的相关参数

配置文件中注意配置 Service,binding,behaviors. Service中配置endpoint 指明abc ,binding中配置tcp通讯的要关参数，behaivor中配置http请求的地址

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
 <system.serviceModel>
 <services>
 <service name="hcbServiceB.User" behaviorConfiguration="userBehavior">
 <endpoint address="net.tcp://localhost:12345/User" binding="netTcpBinding" contract="hcbServiceB.IUser">
  <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="userBehavior">
  <serviceMetadata httpGetEnabled="True" httpGetUrl="http://localhost:8081/User" />
  <serviceDebug includeExceptionDetailInFaults="True" />
  <serviceThrottling maxConcurrentCalls="1000" maxConcurrentInstances="1000" maxConcurrentSessions="1000" />
 </behavior>
 
 </serviceBehaviors>
 </behaviors>
 </system.serviceModel>

</configuration>

4.启动服务

控制台中启动服务

 static void Main(string[] args)
 {
 Console.WriteLine("初始化...");
 Console.WriteLine("服务运行期间，请不要关闭窗口。");
 Console.Title = "wcf net tcp测试 ";
 var cancelTokenSouce = new CancellationTokenSource();
 ServiceHostManager<User>.StartNew(cancelTokenSouce);
 while (true)
 {
  if (Console.ReadKey().Key == ConsoleKey.Escape)
  {
  Console.WriteLine();
  cancelTokenSouce.Cancel();
  break;
  }
 }
 }
