WCF中的ServiceHost初始化两种方式

在宿主程序中初始化ServiceHost有直接写代码和使用配置文件两种方式。使用ServiceHost首先要引用System.ServiceModel 命名空间。

1 代码方式

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

配置文件代码：

<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();}
