SPSiteAdministration class
SharePoint 2013
Provides an abstraction for operations that require administrator access to the content space of a site collection.
Namespace:
Microsoft.SharePoint.Administration
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
The SPSiteAdministration class provides access to selected site collection properties without requiring access to the site collection itself.
This class encapsulates SPSite and SPWeb objects that contain a request that expects the user to be a global administrator, and that automatically grants full content rights to such a user.
