wcf服務端

1，新建一個“windows窗口程序”名稱為WCFServer2。

?

2。然后加入一個“WCF服務”名稱為Service1。

詳細步驟為：解決方式試圖中，選中“WCFServer2”項目，右鍵，在彈出菜單中選擇“加入->新建項”。

3，雙擊主窗口，在它的Load事件中編寫代碼啟動wcf服務：BasicHttpBinding方式啟動wcf服務。此文件代碼例如以下：

using System.ServiceModel;

using System.ServiceModel.Description;

//…

ServiceHost m_ServiceHost;

//…

private void Form1_Load(object sender, EventArgse)

??????? {

??????????? //NetTcpBinding方式啟動wcf服務?

??????????? m_ServiceHost = new ServiceHost(typeof(Service1));//Service1是wcf服務的類名稱?

??????????? 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中添加一個方法Init,同一時候添加ISvrToCliCallBack接口.

namespace WCFServer2

{

??? // 注意: 使用“重構”菜單上的“重命名”命令，能夠同一時候更改代碼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中實現接口的方法Init初始化。

?? public static ISvrToCliCallBack userCallBack;

??????? //...

???????

??????? public void Init()

??????? {?

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

??????? }

?

?

6,主窗體添加button。

private voidbutton1_Click(object sender, EventArgs e)

??????? {

??????????? Service1.userCallBack.NotifyClientMsg("服務端給client通知啦");?

??????? }

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

?

?

客服端

1，新建一個“windows窗口程序”名稱為WCFClient2。

2，添加服務引用。

服務引用地址到服務端的app.config查看，就是baseAddress。

3.在FormClient中繼承接口IService1Callback，實現方法NotifyClientMsg

4。主窗體啟動是初始化。

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();//調用GetSvrTime獲取到wcfserver上的時間

?

??????? }

??? }

}
