来自WCF服务的方法未显示在客户端应用程序中

Question

我在C#编码方面的最新尝试是学习WCF服务.我正在尝试提供一个非常简单的服务.它有一个非默认方法,它只返回用户输入的整数乘以2的字符串.我已将服务上传到aspspider.com,并创建了一个winforms客户端应用程序.但是,在查看服务类时,它只显示GetData方法.老实说我很困惑,并且无法理解为什么我的方法不会出现在我的生活中.我从命令行使用了svcutil.exe命令,但仍然没有.如果有人能帮助我,我真的很感激!这是我的代码:

服务代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
using System.Web.Services;

namespace WcfService1
{
    public class Service1 : IService1
    {        
        public string GetData(int value)
        {
            return string.Format("You entered: {0}", value);
        }

        public string GetDouble(int value) //Method that isn't showing up
        {
            return (value * 2).ToString();
        }
     }
  }

服务接口:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

namespace WcfService1
{
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string GetData(int value);

        [OperationContract]
        public string GetDouble(int value); //Method that isn't showing up

        // TODO: Add your service operations here
    }   
}

Service1Client(注意这很麻烦.还在试图弄清楚如何在这里格式化代码):

这甚至正确编译？接口无法声明其中方法的可见性.它们是含蓄公开的.所以这;

[OperationContract]
public string GetDouble(int value);

应该这样;

[OperationContract]
string GetDouble(int value);
