ConfigurationManager.GetSection returns null

Question

Here is my 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>

But when I call it in code, I'm getting a null back

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

I would appreciate any help pointing out what I've done wrong

Answer 1

Using section handlers to group settings in the configuration file

For example you can follow something like the following

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

MSDN ConfigurationManager.GetConfig Method

如果您正在测试您的类，您必须将配置复制到您的测试项目中的app.config 。

using immediate window check which config file it is pointing to. in my case i had app.config which i am expecting it to read, but on using the command. ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None) it is pointing to something else like nuintrunner.exe.config as that info is loaded into bin. this help in loading the right configuration file
