C＃错误：成员名称不能与其封闭类型和接口声明类型相同

我正在尝试为windows Azure提供appFabric服务。我是实现和EchoService，我需要通过方式和IEchoContract接口实现，所有这些都在服务器端。所以我这样做。在IEchoContract.cs上

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;


namespace Service
{
[ServiceContract(Name = "EchoContract", Namespace = "http://samples.microsoft.com/ServiceModel/Relay/")]
interface IEchoContract
{
    public interface IEchoContract
    {
        [OperationContract]
        string Echo(string text);
    }
}}

在EchoSErvice.cs上

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;

namespace Service
{
class EchoService
{
    [ServiceBehavior(Name = "EchoService", Namespace = "http://samples.microsoft.com/ServiceModel/Relay/")]
    public class EchoService : IEchoContract
    {
        public string Echo(string text)
        {
            Console.WriteLine("Echoing: {0}", text);
            return text;
        }
    }}}

我有两个错误，我不是C＃的专家所以第一个：当我把EchoService：IEchoContract我得到了

'EchoService': member names cannot be the same as their enclosing type

第二，当我把公共接口IEchoContract

'IEchoContract' : interfaces declare types

所以请帮忙。谢谢。

您已经声明了接口和类两次 - 只声明一次。 IEchoContract.cs：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;

namespace Service
{
    [ServiceContract(Name = "EchoContract", Namespace = "http://samples.microsoft.com/ServiceModel/Relay/")]
    public interface IEchoContract
    {
        [OperationContract]
        string Echo(string text);
    }
}

EchoService.cs：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;

namespace Service
{
    [ServiceBehavior(Name = "EchoService", Namespace = "http://samples.microsoft.com/ServiceModel/Relay/")]
    public class EchoService : IEchoContract
    {
        public string Echo(string text)
        {
            Console.WriteLine("Echoing: {0}", text);
            return text;
        }
    }
}

如果您在代码中看到一个名为EchoService的类中有一个名为EchoSevice的类

namespace Service
{
  class EchoService
  {
    [ServiceBehavior(Name = "EchoService", Namespace = "http://samples.microsoft.com/ServiceModel/Relay/")]
    public class EchoService : IEchoContract
    ...

尝试删除外部类，因为它没有意义

namespace Service
{
  [ServiceBehavior(Name = "EchoService", Namespace = "http://samples.microsoft.com/ServiceModel/Relay/")]
  public class EchoService : IEchoContract
  ...

您还必须删除外部接口，因为它们也被定义了两次（可能是您的类最终定义两次的原因）
