WCF中的ServiceHost初始化两种方式

1 代码方式 

1 2 3 4 5 6 7 8 9 10

using(ServiceHost host=new ServiceHost(typeof(HelloWordService)))  {      host.AddServiceEndpoint(typeof(IHelloWordService),          new BasicHttpBinding(), new Uri("http://localhost:10000/HelloWorldService"));      host.AddServiceEndpoint(typeof(IHelloWordService),          new NetTcpBinding(), new Uri("net.tcp://localhost:10001/HelloWorldService"));          if (host.State != CommunicationState.Opening)          host.Open();  }

2 配置文件方式

<services>
  <service behaviorConfiguration="serverBehavior" name="HelloWordService">
    <endpoint address="http://localhost:10000/HelloWorldService" 
              binding="basicHttpBinding" contract="IHelloWordService"></endpoint>
    <endpoint address="net.tcp://localhost:10001/HelloWorldService" 
              binding="netTcpBinding" contract="IHelloWorldService"></endpoint>
  </service>
</services>

当然也可以使用基地址的方式来配置

<services>
  <service behaviorConfiguration="serverBehavior" name="HelloWordService">
    <endpoint address="HelloWorldService" 
              binding="basicHttpBinding" contract="IHelloWordService"></endpoint>
    <endpoint address="HelloWorldService" 
              binding="netTcpBinding" contract="IHelloWorldService"></endpoint>
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:10000/"/>
        <add baseAddress="net.tcp://localhost:10001/"/>
      </baseAddresses>
    </host>
  </service>
</services>

配置好配置文件后就宿主程序中就很简单了，如下：

using(ServiceHost host=new ServiceHost(typeof(HelloWordService)))
{
    if (host.State != CommunicationState.Opening)
        host.Open();
}
