WCF教學(6) - 使用ChannelFactory呼叫服務

延續 WCF教學(5) - 使用程式裝載服務
若用戶端已有服務合約、與資料合約的參考(如用戶端和服務端都是自己寫的)，你可以改用ChannelFactory<T> 來建立proxy，透過它呼叫服務。
例如延續前面範例

• 修改用戶端的Main方法：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            //        ServiceReference1.IMyService proxy =
            //new ServiceReference1.MyServiceClient();
            //        string result = proxy.Add(3, 4);
            //        Console.WriteLine(result);
            ServiceReference1.IMyService proxy =
                ChannelFactory<ServiceReference1.IMyService>.CreateChannel(
                new BasicHttpBinding(),
                new EndpointAddress("http://localhost:8732/Design_Time_Addresses/WcfServiceLibrary1/Service1/"));
            string result;
            result = proxy.Add(3, 4);
            Console.WriteLine(result);
            if ((proxy as ICommunicationObject).State ==
                CommunicationState.Opened)
            {
                (proxy as ICommunicationObject).Close();
            }
        }
    }
}

• 按CTRL + F5執行，Client可以正確呼叫Service
