The examples in this section show how to get the IsDeclared property value after accessing the related section information in the configuration file.

The following example gets the SectionInformation object.

// 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;

' Get the current configuration file.
Dim config _
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

The following example gets the IsDeclared value.

bool declared =
    sInfo.IsDeclared;
Console.WriteLine("Section declared?: {0}",
    declared.ToString());

Dim declared As Boolean = _
sInfo.IsDeclared
Console.WriteLine("Section declared?: {0}", _
declared.ToString())
