myWebPermission2->Demand();

 // Create another WebPermission instance that is the copy of the above WebPermission instance.
  WebPermission myWebPermission2 = (WebPermission) myWebPermission1.Copy();

 // Check whether all callers higher in the call stack have been granted the permissionor not.
 myWebPermission2.Demand();

' Create another WebPermission instance that is the copy of the above WebPermission instance.
Dim myWebPermission2 As WebPermission = CType(myWebPermission1.Copy(), WebPermission)

' Check whether all callers higher in the call stack have been granted the permissionor not.
myWebPermission2.Demand()
