用 C# 实现一个简单的 Restful Service 供外部调用，大体总结为4点：

The service contract (the methods it offers).
How do you know which one to access from the URL given (URL Routing).
The implementation of the service.
How you will host the service.

详细的基本步骤如下所示：

1）：工程结构（Class Library Project）

2）： IRestDemoService.cs

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.ServiceModel;using System.ServiceModel.Web;namespace EricSunRestService{    [ServiceContract(Name = "RestDemoServices")]    public interface IRestDemoServices    {        [OperationContract]        [WebGet(UriTemplate = Routing.GetClientRoute, BodyStyle = WebMessageBodyStyle.Bare)]        string GetClientNameById(string Id);    }    public static class Routing    {        public const string GetClientRoute = "/Client/{id}";    }}

3）：RestDemoService.cs

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.ServiceModel;using System.ServiceModel.Activation;namespace EricSunRestService{    [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Single, IncludeExceptionDetailInFaults = true)]    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]    public class RestDemoServices : IRestDemoServices    {        public string GetClientNameById(string Id)        {            string ReturnString = "HaHa id is: " + Id;            return ReturnString;        }    }}

4）：Host Service 工程结构（Console Application）

5）：Program.cs

using System;using System.Collections.Generic;using System.Linq;using System.Text;using EricSunRestService;using System.ServiceModel.Web;namespace EricSunHostService{    class Program    {        static void Main(string[] args)        {            RestDemoServices demoServices = new RestDemoServices();            WebServiceHost _serviceHost = new WebServiceHost(demoServices, new Uri("http://localhost:8000/DemoService"));            _serviceHost.Open();            Console.ReadKey();            _serviceHost.Close();        }    }}

6）：运行Host程序，在浏览器中输入对应Service的Url
