WCF返回JSON格式数据问题
关键代码如下：
public interface IService
  {
  [OperationContract(Name="sayHelloJson")]
  [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "sayHello", BodyStyle = WebMessageBodyStyle.Wrapped)]
  String sayHello();
  [OperationContract(Name = "SendMessageJson")]
  [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, UriTemplate = "SendMessage?Message={Message}", BodyStyle = WebMessageBodyStyle.Wrapped)]
  String SendMessage(String Message);
  }

static void Main(string[] args)
  {
  Uri ea = new Uri("http://localhost:8000/Service");
  WebHttpBinding bb = new WebHttpBinding();
  ServiceHost sh = new ServiceHost(typeof(Service),ea);
  ServiceMetadataBehavior behave = new ServiceMetadataBehavior();
  behave.HttpGetEnabled = true;
  sh.Description.Behaviors.Add(behave);
  sh.AddServiceEndpoint(typeof(IService),bb,ea);
  try
  {
  sh.Open();
  Console.WriteLine("启动成功……");
  Console.ReadLine();
  sh.Close();
  }
  catch
  {
  Console.WriteLine("启动失败……");
  }

  }
没使用配置文件
浏览器访问http://localhost:8000/Service正常
现在想在浏览器中查看sayHello方法的返回数据
http://localhost:8000/Service/Json/sayHello无法打开
到底哪里有问题？

http://localhost:8000/Service/Json/sayHello无法打开

另外ServiceHost要改成WebServiceHost，否则还要麻烦添加Dispatch Behaviour。
