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

}

}

}
