1.和服务端一样的契约接口ITest

namespace WcfService.Client
{
	[ServiceContract]
	public interface ITest
	{
		[OperationContract]
		string GetHello();
	}
}

必须和服务端的契约一致

2.配置客服端配置文件

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
	<system.serviceModel>
		<client>
			<endpoint address="http://localhost:8080/wcf/http" binding="basicHttpBinding" contract="WcfService.Client.ITest" name="testHttp"/>
			<endpoint address="net.tcp://localhost:8081/wcf/nettcp" binding="netTcpBinding" contract="WcfService.Client.ITest" name="testNetTcp"/>
		</client>
	</system.serviceModel>
</configuration>

此处会使用client配置节在endpoint中的address填写服务中配置的绝对地址+相对地址，协议和契约要一致；

3.实例化出服务传输的对象实例

namespace WcfService.Client
{
	class Program
	{
		static void Main(string[] args)
		{
			var porxy = new ChannelFactory<ITest>("testHttp");
			ITest testHttp =  porxy.CreateChannel();
			Console.WriteLine(testHttp.GetHello());
			porxy.Close();

			porxy = new ChannelFactory<ITest>("testNetTcp");
			ITest testNetTcp = porxy.CreateChannel();
			Console.WriteLine(testNetTcp.GetHello());
			porxy.Close();
			Console.ReadLine();
		}
	}
}
