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:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel; namespace y.WcfFirst.Client.Proxys { [ServiceContract] public interface IHello { [OperationContract] string Say(string name); } }
客户端代理类:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel; using System.ServiceModel.Channels; namespace y.WcfFirst.Client.Proxys { public class HelloProxy:ClientBase<IHello>,IHello { public HelloProxy() : base() { } public string Say(string name) { return base.Channel.Say(name); } } }
客户端app.config文件:
<?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <client> <endpoint name="wcfFirst" address="net.tcp://localhost:6666/hello" binding="netTcpBinding" contract="y.WcfFirst.Client.Proxys.IHello"></endpoint> </client> </system.serviceModel> </configuration>
客户端的调用:
using (HelloProxy proxy = new HelloProxy()) { Console.WriteLine("Recevie from Server:{0}", proxy.Say(name)); proxy.Close(); }
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。
using (HelloClient clientProxy = new HelloClient()) { Console.WriteLine("Recevie from Server:{0}", clientProxy.Say(name)); clientProxy.Close(); }
二、通过通道方式调用服务操作
1.客户端契约,如下
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel; namespace y.WcfFirst.ClientChannel.Proxy { [ServiceContract] public interface IHello { [OperationContract] string Say(string name); } }
2.客户端配置文件的设置:如下:
<?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <client> <endpoint name="wcfFirst" address="net.tcp://localhost:6666/hello" binding="netTcpBinding" contract="y.WcfFirst.ClientChannel.Proxy.IHello"></endpoint> </client> </system.serviceModel> </configuration>
3.客户端调用服务操作:如下:
ChannelFactory<IHello> factory = new ChannelFactory<IHello>("wcfFirst"); IHello channelProxy = factory.CreateChannel(); using(channelProxy as IDisposable) { Console.WriteLine("Recevie from Server:{0}", channelProxy.Say(name)); }
