Examples

The examples in this section show how to get the AllowDefinition 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 AllowDefinition value.

ConfigurationAllowDefinition allowDefinition =
    sInfo.AllowDefinition;
Console.WriteLine("Allow definition: {0}", 
    allowDefinition.ToString() );

Dim allowDefinition _
As ConfigurationAllowDefinition = _
sInfo.AllowDefinition
Console.WriteLine("Allow definition: {0}", _
allowDefinition.ToString())

Remarks

AllowDefinition applies only to configuration files of Web applications. For client applications, you must use AllowExeDefinition.
