WCF:初识

结构：

 using System.ServiceModel;
 namespace MyServices
 {
     [ServiceContract]
     public interface IHomeService
     {
         [OperationContract]
         int GetLength(string name);
     }
 }

契约

 namespace MyServices
 {
     public class HomeService:IHomeService
     {
         public int GetLength(string name)
         {
             return name.Length;
         }
     }
 }

实现类

 using System;
 using System.ServiceModel;

 namespace MyServices
 {
     class Program
     {
         static void Main(string[] args)
         {
             using (ServiceHost host = new ServiceHost(typeof(HomeService)))
             {
                 try
                 {
                     host.Open();
                     Console.WriteLine("服务开启！");
                     Console.Read();
                 }
                 catch (Exception e)
                 {
                     Console.WriteLine(e.Message);
                 }
             }
         }
     }
 }

服务启动

 using System;
 namespace ConsoleApplication1
 {
     class Program
     {
         static void Main(string[] args)
         {
             HomeServiceReference.HomeServiceClient client = new HomeServiceReference.HomeServiceClient();
             //HomeServiceClient homeServiceClient = new HomeServiceClient();
             var r = client.GetLength("abc");
             Console.WriteLine(r);
             Console.ReadKey();
         }
     }
 }
