结构：

 1 using System.ServiceModel;
 2 namespace MyServices
 3 {
 4     [ServiceContract]
 5     public interface IHomeService
 6     {
 7         [OperationContract]
 8         int GetLength(string name);
 9     }
10 }
契约 
 1 namespace MyServices
 2 {
 3     public class HomeService:IHomeService
 4     {
 5         public int GetLength(string name)
 6         {
 7             return name.Length;
 8         }
 9     }
10 }
实现类 
 1 using System;
 2 using System.ServiceModel;
 3 
 4 namespace MyServices
 5 {
 6     class Program
 7     {
 8         static void Main(string[] args)
 9         {
10             using (ServiceHost host = new ServiceHost(typeof(HomeService)))
11             {
12                 try
13                 {
14                     host.Open();
15                     Console.WriteLine("服务开启！");
16                     Console.Read();
17                 }
18                 catch (Exception e)
19                 {
20                     Console.WriteLine(e.Message);
21                 }
22             }
23         }
24     }
25 }
服务启动 
 1 using System;
 2 namespace ConsoleApplication1
 3 {
 4     class Program
 5     {
 6         static void Main(string[] args)
 7         {
 8             HomeServiceReference.HomeServiceClient client = new HomeServiceReference.HomeServiceClient();
 9             //HomeServiceClient homeServiceClient = new HomeServiceClient();
10             var r = client.GetLength("abc");
11             Console.WriteLine(r);
12             Console.ReadKey();
13         }
14     }
