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;  } } }
