SPSite Constructor (Guid)
Initializes a new instance of the SPSite class based on the specified ID for a site collection.
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
Available in Sandboxed Solutions: Yes
Available in SharePoint Online
This constructor is allowed in sandboxed solutions. In that case, the value of the id parameter must resolve to the value of the ID property of the parent site collection in which the sandboxed solution is deployed. If the value of the id parameter resolves to the value of the ID property of any other site collection, the constructor throws an exception because a sandboxed solution is not allowed to access any SharePoint objects outside of its hosting site collection.
