WCF原理性的东西，暂时还没有深入研究，只是在公司的项目中使用到了，会调用，然后再多做了一些了解，现在将它抽出来了一个小实例，写了一个WCF的demo。

　　我写的这个WCF.Demo主要包括数据契约和服务契约，UI客户端层和Host宿主层，基于http和net.tcp两种协议通信。

　　不多说，直接贴一张层次图片先，最后提供源码下载。

　　

 

　　数据契约层（DataContracts）代码：

　　

using System;using System.Collections.Generic;using System.Linq;using System.Runtime.Serialization;using System.Text;using System.Threading.Tasks;namespace WCF.DataContracts{    [DataContract()]    public class CustomerData    {        [DataMember()]        public string Name { set; get; }        [DataMember()]        public string Sex { set; get; }    }}

 

服务契约接口层（WCF.ServiceContracts）

using System;using System.Collections.Generic;using System.Linq;using System.ServiceModel;using System.Text;using System.Threading.Tasks;namespace WCF.ServiceContracts{    [ServiceContract()]    public interface ICustomerService    {        [OperationContract()]        string ShowInfo();    }}

服务契约实现层（WCF.Services）

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using WCF.DataContracts;using WCF.ServiceContracts;namespace WCF.Services{    public class CustomerService : ICustomerService    {        public string ShowInfo()        {            CustomerData data = new CustomerData()            {                Name = "admin",                Sex = "男"            };            return "姓名是：" + data.Name + "，性别是：" + data.Sex;        }    }}

宿主层（两个文件）

Program

using System;using System.Collections.Generic;using System.Linq;using System.ServiceModel;using System.Text;using System.Threading.Tasks;using WCF.Services;namespace WCF.Hosting{    class Program    {        static void Main(string[] args)        {            ServiceHost hostForHello = new ServiceHost(typeof(CustomerService));            hostForHello.Open();            Console.WriteLine("WCF服务启动成功！");            Console.ReadLine();        }    }}

app.config

客户端调用层（WCF.Client）

using System;using System.Collections.Generic;using System.Linq;using System.ServiceModel;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using WCF.ServiceContracts;namespace WCF.Client{    public partial class WebForm1 : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {            using (ChannelFactory
     
       channelFactory = new ChannelFactory
      
       ("helloEndPoint"))            {                ICustomerService helloService = channelFactory.CreateChannel();                using (helloService as IDisposable)                {                    TextBox1.Text = helloService.ShowInfo();                }            }        }    }}
