SPUtility.ValidateFormDigest method

SharePoint 2013

Validates the form digest control that is used in the current request.

Namespace:  Microsoft.SharePoint.Utilities
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)
C#
VB
Copy 
[SubsetCallableExcludeMemberAttribute(SubsetCallableExcludeMemberType.PerSpec)]
public static bool ValidateFormDigest()

Return value

Type: System.Boolean
true if the form digest control is valid; otherwise, false.

If the method that is passed to the RunWithElevatedPrivileges method includes a write operation, either of the SPUtility.ValidateFormDigest() or SPWeb.ValidateFormDigest() methods should be called before a call is made to RunWithElevatedPrivileges.

For information about the control that is used for security validation, see Microsoft.SharePoint.WebControls.FormDigest.
