SPUtility.GetGuidFromShortGuid method

SharePoint 2013

This method is used to decode the "base64url" encoded string (see http://tools.ietf.org/html/rfc4648) back to a normal GUID.

Namespace:  Microsoft.SharePoint.Utilities
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)
C#
VB
Copy 
public static Guid GetGuidFromShortGuid(
	string shortGuid
)

Parameters

shortGuid
Type: System.String

Return value

Type: System.Guid
the Guid value

The bases64url format is basically base 64 except that it: 1) replaces '+' with '-' 2) replaces '/' with '_' 3) trims '=' padding at the end
