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 …

我有一个使用Parse API的XCode项目,但我现在正在尝试将可可触摸包装器集成到spotify中.我得到一个非常令人沮丧的链接器错误,我已经在两个小时工作,但没有用.任何帮助将非常感激!这是错误.谢谢!
