WCF服务端调用client.

wcf服务端

1，新建一个“windows窗口程序”名称为WCFServer2。

2。然后加入一个“WCF服务”名称为Service1。

详细步骤为：解决方式试图中，选中“WCFServer2”项目，右键，在弹出菜单中选择“加入->新建项”。

3，双击主窗口，在它的Load事件中编写代码启动wcf服务：BasicHttpBinding方式启动wcf服务。此文件代码例如以下：

using System.ServiceModel;

using System.ServiceModel.Description;

//…

ServiceHost m_ServiceHost;

//…

private void Form1_Load(object sender, EventArgse)

        {

            //NetTcpBinding方式启动wcf服务 

            m_ServiceHost = new ServiceHost(typeof(Service1));//Service1是wcf服务的类名称 

            NetTcpBindingbinding = new NetTcpBinding();

            UribaseAddress = new Uri(string.Format("net.tcp://localhost:10086/WCFHostServer/Service1"));

            m_ServiceHost.AddServiceEndpoint(typeof(IService1),binding, baseAddress);

           

            m_ServiceHost.Open();

        }

4，在 IService1.cs中添加一个方法Init,同一时候添加ISvrToCliCallBack接口.

namespace WCFServer2

{

    // 注意: 使用“重构”菜单上的“重命名”命令，能够同一时候更改代码和配置文件里的接口名“IService1”。

    [ServiceContract(CallbackContract= typeof(ISvrToCliCallBack))]

    public interface IService1

    {

        [OperationContract]

        voidDoWork();

 

        [OperationContract]

        voidInit();

    }

 

    public interface ISvrToCliCallBack

    {

        [OperationContract(IsOneWay= true)]

        voidNotifyClientMsg(string devStateInfo);

    }

}

5, 在Service1.cs中实现接口的方法Init初始化。

   public static ISvrToCliCallBack userCallBack;

        //...

       

        public void Init()

        { 

            userCallBack = OperationContext.Current.GetCallbackChannel<ISvrToCliCallBack>();

        }

 

6,主窗体添加button。

private voidbutton1_Click(object sender, EventArgs e)

        {

            Service1.userCallBack.NotifyClientMsg("服务端给client通知啦"); 

        }

7。改动app.config，WCFServer2.Service1的binding由"wsHttpBinding"改成"wsDualHttpBinding"

 

 

客服端

1，新建一个“windows窗口程序”名称为WCFClient2。

2，添加服务引用。

服务引用地址到服务端的app.config查看，就是baseAddress。

3.在FormClient中继承接口IService1Callback，实现方法NotifyClientMsg

4。主窗体启动是初始化。

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

 

using WCFClient2.ServiceReference1;

using System.ServiceModel;

 

 

namespace WCFClient2

{

    public partial class Form1 : Form, IService1Callback

    {

        publicForm1()

        {

            InitializeComponent();

        }

 

        public void NotifyClientMsg(stringdevStateInfo)

        {

            MessageBox.Show(devStateInfo,"ddd");

        }

 

        IService1m_Innerclient;

 

        privatevoid Form1_Load(objectsender, EventArgs e)

        {

            InstanceContextm_CallBackContext;

            m_CallBackContext = new InstanceContext(this);

 

            DuplexChannelFactory<IService1> m_ChannelFactory;

            NetTcpBindingbinding = new NetTcpBinding();

            stringstrUrl = string.Format("net.tcp://{0}:{1}/WCFHostServer/Service1",

                "localhost",10085);

            UribaseAddress = new Uri(strUrl);

            m_ChannelFactory = new DuplexChannelFactory<IService1>(m_CallBackContext, binding, new EndpointAddress(baseAddress));

            m_Innerclient =m_ChannelFactory.CreateChannel();

 

            Service1Clienthost = new ServiceReference1.Service1Client(m_CallBackContext);

            host.Init();//调用GetSvrTime获取到wcfserver上的时间

 

        }

    }

}
