How do you use sections in c# 4.0 app.config?

Question

I want to use my app config to store the settings for 2 companys, and i\'d prefer if it was possible to use a section to seperate the data for one from the other rather then

Answer 1

<configSections>
  <section name="FBI" type="System.Configuration.NameValueSectionHandler" />
  <section name="FSCS" type="System.Configuration.NameValueSectionHandler" />
</configSections>

<FSCS>
  <add key="processingDirectory" value="C:\testfiles\ProccesFolder"/>
</FSCS>
<FBI>
  <add key="processingDirectory" value="C:\testfiles\ProccesFolder"/>
</FBI>

And then:

var section = ConfigurationManager.GetSection("FSCS") as NameValueCollection;
var value = section["processingDirectory"];

Answer 2

App.config

<configSections>
  <sectionGroup name="FileCheckers">
    <section name="FBI" type="System.Configuration.NameValueSectionHandler" />
    <section name="FSCS" type="System.Configuration.NameValueSectionHandler" />
  </sectionGroup>
</configSections>

<FileCheckers>
  <FSCS>
    <add key="processingDirectory" value="C:\testfiles\ProccesFolder"/>
  </FSCS>
  <FBI>
    <add key="processingDirectory" value="C:\testfiles\ProccesFolder"/>
  </FBI>
</FileCheckers>

Example Usage

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ConfigurationSectionGroup fileCheckersGroup = config.SectionGroups["FileCheckers"];
foreach (ConfigurationSection section in fileCheckersGroup.Sections)
{
    NameValueCollection sectionSettings = ConfigurationManager.GetSection(section.SectionInformation.SectionName) as NameValueCollection;
    var value = sectionSettings["processingDirectory"]
}
