WCF 客户端调用服务操作的两种方法

本节的主要内容:1、通过代理类的方式调用服务操作。2、通过通道的方式调用服务操作。3、代码下载

一、通过代理类的方式调用服务操作(两种方式添加代理类)

1.手动编写代理类,如下:

客户端契约:

View Code
 1 using System;
2 using System.Collections.Generic;
3 using System.Linq;
4 using System.Text;
5
6 using System.ServiceModel;
7 namespace y.WcfFirst.Client.Proxys
8 {
9 [ServiceContract]
10 public interface IHello
11 {
12 [OperationContract]
13 string Say(string name);
14 }
15 }

客户端代理类:

View Code
 1 using System;
2 using System.Collections.Generic;
3 using System.Linq;
4 using System.Text;
5
6 using System.ServiceModel;
7 using System.ServiceModel.Channels;
8 namespace y.WcfFirst.Client.Proxys
9 {
10 public class HelloProxy:ClientBase<IHello>,IHello
11 {
12 public HelloProxy()
13 : base()
14 {
15 }
16
17 public string Say(string name)
18 {
19 return base.Channel.Say(name);
20 }
21 }
22 }

客户端app.config文件:

View Code
 1 <?xml version="1.0" encoding="utf-8" ?>
2 <configuration>
3 <system.serviceModel>
4 <client>
5 <endpoint name="wcfFirst"
6 address="net.tcp://localhost:6666/hello"
7 binding="netTcpBinding"
8 contract="y.WcfFirst.Client.Proxys.IHello"></endpoint>
9 </client>
10 </system.serviceModel>
11 </configuration>

客户端的调用:

View Code
1 using (HelloProxy proxy = new HelloProxy())
2 {
3 Console.WriteLine("Recevie from Server:{0}", proxy.Say(name));
4 proxy.Close();
5 }

2.通过Metadata方式产生代理类。

服务端需要对app.config进行配置如下:

客户端的操作步骤:先运行服务端(host)。

a.在客户端点击Add Service Reference按钮,添加Service引用。如下图:

b.输入Address地址:http://localhost:8888,点击"GO",获取服务操作。并且重命名Namespace,如下图:

c.客户端对代理类的调用。

View Code
1  using (HelloClient clientProxy = new HelloClient())
2 {
3 Console.WriteLine("Recevie from Server:{0}", clientProxy.Say(name));
4 clientProxy.Close();
5 }

二、通过通道方式调用服务操作

1.客户端契约,如下:

View Code
 1 using System;
2 using System.Collections.Generic;
3 using System.Linq;
4 using System.Text;
5
6 using System.ServiceModel;
7 namespace y.WcfFirst.ClientChannel.Proxy
8 {
9 [ServiceContract]
10 public interface IHello
11 {
12 [OperationContract]
13 string Say(string name);
14 }
15 }

2.客户端配置文件的设置:如下:

View Code
 1 <?xml version="1.0" encoding="utf-8" ?>
2 <configuration>
3 <system.serviceModel>
4 <client>
5 <endpoint name="wcfFirst"
6 address="net.tcp://localhost:6666/hello"
7 binding="netTcpBinding"
8 contract="y.WcfFirst.ClientChannel.Proxy.IHello"></endpoint>
9 </client>
10 </system.serviceModel>
11 </configuration>

3.客户端调用服务操作:如下:

View Code
1 ChannelFactory<IHello> factory = new ChannelFactory<IHello>("wcfFirst");
2 IHello channelProxy = factory.CreateChannel();
3 using(channelProxy as IDisposable)
4 {
5 Console.WriteLine("Recevie from Server:{0}", channelProxy.Say(name));
6 }
