As System.Configuration.Configuration = _
ConfigurationManager.OpenExeConfiguration( _
ConfigurationUserLevel.None)

' Get the section.
Dim section As UrlsSection = _
CType(config.GetSection("MyUrls"), UrlsSection)

Dim sInfo As SectionInformation = _
section.SectionInformation


// Get the current configuration file.
System.Configuration.Configuration config =
        ConfigurationManager.OpenExeConfiguration(
        ConfigurationUserLevel.None);

// Get the section.
UrlsSection section =
    (UrlsSection)config.GetSection("MyUrls");


SectionInformation sInfo =
    section.SectionInformation;
