一个WCF使用TCP协议进行通协的例子

在解决方案资源管理器中,需要添加两个引用:System.ServiceModel和WCFService。然后双击窗口,在Form_Load事件中编写如下代码:

  添加一个应用程序配置文件App.Config,然后粘贴如下内容:

对于这个配置文件,我是这样理解的:

1、baseAddress:由协议、地址和端口三个部分组成。其中net.tcp对应TCP协议,http对应Http协 议。

2、endPoint:该属性有一个address属性,指的是在baseAddress基础上增加address属性等于一个 完整的路径。contract则是对应程序接口,这个就不多说。而每种协议都是对应WCFService.IService1契约。

到现在,WCF宿主程序就已经建立好了,我们编译并在"非VS环境下"运行WCFHost应用程序。

三、建立客户端应用程序

  在解决方案上按右键,选择"添加" -> "新建项目",然后新建一个Windows 窗体应用程序,程序名称为"WCFClient"。0004

  然后在项目上按右键,选择"添加服务引用",在弹出的添加服务引用中,输入baseAddRess地址 :http://localhost:8001,然后点击“前往”,当确定没问题后,点击“确定”按钮。

  在客户端程序中,会自动产生一个app.config文件,双击打开该文件,我们可以在"client"段 中可以看到,net.tcp和Http两种协议属性下面都有一个"name"属性。通过这个"name"属性,我们可 以控制使用什么协议与访问服务端。

我们现在为程序添加一个按钮,双击后编写如下代码:

private void button1_Click(object sender, EventArgs e)
{   
    WCFClient.ServiceReference1.Service1Client sc = new
    ServiceReference1.Service1Client("TcpBinding");  
    sc.Open();   
    MessageBox.Show(sc.GetData(10));    sc.Close();
}

就个Demo这么简单就完成了。
