• 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:

    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);
        }
    }
    View Code

    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);
            }
        }
    }
    View Code

    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>
    View Code

    客户端的调用:

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

    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();
    }
    View Code

    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);
        }
    }
    View Code

    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>
    View Code

    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));
                    }
    View Code
