ConfigurationSectionGroup Class
Assembly: System.Configuration (in system.configuration.dll)
Because some configuration sections are related, it is often convenient to group them together within a single section group. The ConfigurationSectionGroup class represents the sectionGroup XML element within a configuration file.
Use the Sections property to access the sections contained in this ConfigurationSectionGroup.
A ConfigurationSectionGroup can also contain other ConfigurationSectionGroup objects, which can be accessed through the SectionGroups property.
The following code example shows how to use ConfigurationSectionGroup.
Imports System Imports System.Collections Imports System.Configuration Class UsingConfigurationSectionGroup Private Shared indentLevel As Integer = 0 Public Shared Sub Main(ByVal args() As String) ' Get the application configuration file. Dim config _ As System.Configuration.Configuration = _ ConfigurationManager.OpenExeConfiguration( _ ConfigurationUserLevel.None) ' Get the collection of the section groups. Dim sectionGroups _ As ConfigurationSectionGroupCollection = _ config.SectionGroups ShowSectionGroupCollectionInfo(sectionGroups) End Sub 'Main Shared Function getSpacer() As String Dim spacer As String = "" Dim i As Integer For i = 0 To indentLevel - 1 spacer = spacer + " " Next i Return spacer End Function 'getSpacer Overloads Shared Sub ForceDeclaration( _ ByVal sectionGroup As ConfigurationSectionGroup) ' Get the application configuration file.
