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
