在.NET 4.5框架不存在ConfigurationManager中类 [英] ConfigurationManager Class not exist on .NET 4.5 Framework

问题描述

我刚开始使用.NET框架4.5的C＃的工作。我使用Windows窗体应用程序。我已经做了必要的进口，如：

 使用System.Configuration;
 

但实际上ConfigurationManager中的类似乎是不退出。我曾尝试使用ConfigurationSettings代替，但视觉STDIO告诉我，这是过时的，由ConfigurationManager中更换！

这是code块相关的问题：

  Int32.Parse StartingMonth = int.parse（ConfigurationManager.AppSettings [StartingMonthColumn]）;
 

所以，你能帮帮我吗？

解决方案

1. 确保 System.Configuration.dll 您添加到项目中。如果你已经添加了它，尝试删除并重新添加。
2. 把光标放在 ConfigurationManager中则preSS <大骨节病> CTRL + ，看看它表明你
