Represents a group of related sections within a configuration file.

Thetype exposes the following members.
|IsDeclarationRequired||Gets a value that indicates whether this object declaration is required.|
|IsDeclared||Gets a value that indicates whether this object is declared.|
|Name||Gets the name property of this object.|
|SectionGroupName||Gets the section group name associated with this .|
|SectionGroups||Gets a ConfigurationSectionGroupCollection object that contains all the objects that are children of this object.|
|Sections||Gets a ConfigurationSectionCollection object that contains all of ConfigurationSection objects within this object.|
|Type||Gets or sets the type for this object.|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|ForceDeclaration()||Forces the declaration for this object.|
|ForceDeclaration(Boolean)||Forces the declaration for this object.|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ShouldSerializeSectionGroupInTargetVersion||Indicates whether the current instance should be serialized when the configuration object hierarchy is serialized for the specified target version of the .NET Framework.|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
Settings in configuration files (such as the Web.config file) are organized into sections. Because some sections are related, it is often convenient to group them in a section group. The class represents the sectionGroup XML element that is used to group sections when they are defined in the configSections element of a configuration file. Section groups can be nested (a section group can contain other section groups as well as sections). The following example shows a configSections element that defines three nested section groups:
<configSections> <sectionGroup name="system.web.extensions"...> <sectionGroup name="scripting" ...> <section name="scriptResourceHandler".../> <sectionGroup name="webServices"...> <section name="jsonSerialization" .../> <section name="profileService" ... /> <section name="authenticationService" .../> <section name="roleService" .../> </sectionGroup> </sectionGroup> </sectionGroup> </configSections>
The configuration system loads settings from configuration files into objects. You can use the Sections and SectionGroups properties to access the sections and section groups that are contained in a object.
For more information about how to access information from configuration files, see the ConfigurationManager class.
The following example shows how to use the class to retrieve configuration settings. The example is a console application that reads configuration settings and writes information about each configuration section group and the sections in it to the console.
The Main method loads the configuration settings into a Configuration object, retrieves the SectionGroups collection from the Configuration object, and then calls the ShowSectionGroupCollectionInfo method to display the section property values.
The ShowSectionGroupCollectionInfo method iterates through the section groups and calls the ShowSectionGroupInfo method for each one.
The ShowSectionGroupInfo method displays the name of the section group, some property values, and the names of the sections that it contains. If the section group contains section groups, this method calls ShowSectionGroupCollectionInfo recursively to display those section groups.
The indentLevel field is used to add spaces to the left side of displayed lines to show logical groupings. All lines are limited to 79 characters of text to avoid line wrapping, which would make it harder to distinguish the logical groupings.
