超简单WCF例子

项目图如下：

 1 using System;

 2 using System.ServiceModel;

 3 

 4 namespace ServiceLib

 5 {

 6     [ServiceContract]

 7     public interface ICalcService

 8     {

 9         /// <summary>

10         /// 欢迎方法

11         /// </summary>

12         /// <param name="name"></param>

13         /// <returns></returns>

14         [OperationContract]

15         String WelCome(String name);

16     }

17 }

ICalcService

 1 using System;

 2 

 3 namespace ServiceLib

 4 {

 5     public class CalcService:ICalcService

 6     {

 7         /// <summary>

 8         /// 欢迎

 9         /// </summary>

10         /// <param name="name"></param>

11         /// <returns></returns>

12         public string WelCome(string name)

13         {

14             Console.WriteLine(name);

15             return "你好：" + name;

16         }

17     }

18 }

CalcService

 1 using System;

 2 using System.ServiceModel;

 3 using System.ServiceModel.Description;

 4 

 5 using ServiceLib;

 6 

 7 namespace CalcHost

 8 {

 9     class Program

10     {

11         static void Main(string[] args)

12         {

13             // 指定契约

14             Uri address = new Uri("http://127.0.0.1:8888");

15             ServiceHost host = new ServiceHost(typeof(CalcService),address);

16             host.AddServiceEndpoint(typeof(ICalcService), new WSHttpBinding(), "Calc");

17 

18             // 公开元数据    注：这个上线前关掉应该比较好

19             ServiceMetadataBehavior smb = new ServiceMetadataBehavior();

20             smb.HttpGetEnabled = true;

21             host.Description.Behaviors.Add(smb);

22 

23             // 开启服务

24             host.Opened += (a, b) => Console.WriteLine("服务已开启");

25             host.Open();

26             Console.Read();

27         }

28     }

29 }

CalcHost.Program

 1 using Client.ServiceReference;

 2 using System;

 4 namespace Client

 5 {

 6     class Program

 7     {

 8         static void Main(string[] args)

 9         {

10             using (CalcServiceClient service = new CalcServiceClient())

11             {

12                 Console.WriteLine("Please input name:");

13                 String name = Console.ReadLine();

14                 Console.WriteLine(service.WelCome(name));

15                 Console.Read();

16             }

17         }
