c# - ConfigurationManager.GetSection 返回 null

Question

这是我的 app.config

<configuration>
  <configSections>
      <section name="procedureList" type="System.Configuration.NameValueSectionHandler, System, Version=4.0.30319, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
  </configSections>

  <procedureList>
    <add key="NAS.spBusObjGetLineProd" value="@area='Melt Shop';@endDt=?date?;@dayonly=1;@obj='Melt Shop Business Objective" />
    <add key="NAS.spBusObjGetLineProd" value="@area='Cold Mill';@endDt=?date?;@dayonly=1;@obj='Cold Mill Business Objective" /> 
  </procedureList>
  <appSettings>
    <add key="Connstr" value=""/>
    <add key="Userid" value=""/>
    <add key="Timeout" value=""/>
  </appSettings>

</configuration>

但是当我在代码中调用它时，我得到一个空值

public void samplemethod()
{
    NameValueCollection nvc = ConfigurationManager.GetSection("procedureList") as NameValueCollection;
    string[] keys = nvc.AllKeys;
}

如能指出我做错的地方，我将不胜感激

Using section handlers to group settings in the configuration file

例如，您可以按照以下内容进行操作

private void ReadSettings()
{
    NameValueCollection loc = 
   (NameValueCollection )ConfigurationSettings.GetConfig("procedureList");
}
