小编use*_*400的帖子

我正在使用2.0 .Net框架在C#visual Studio 2010中编写一个小程序.我正在尝试从App.config文件中读取值.我的配置文件看起来像这样......

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
      <section name="MyApp.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    </sectionGroup> 
  </configSections>
  <applicationSettings>
    <add key="Path" value ="C:\Program Files\MyApp\bin\" />
    <add key="UserName" value="UserName" />
    <add key="Pword" value="Password" />
  </applicationSettings>
</configuration>

然后在我的代码中:

path = ConfigurationManager.AppSettings["Path"];

我收到运行时错误"配置系统无法初始化".从我所看到的,configSection必须是文件中的第一个,但我已经完成了这个并仍然得到错误.
