DBDataPermission.Intersect Method (IPermission)
Returns a new permission object representing the intersection of the current permission object and the specified permission object.
Assembly: System.Data (in System.Data.dll)
A permission object to intersect with the current permission object. It must be of the same type as the current permission object.
Return ValueType: System.Security.IPermission
A new permission object that represents the intersection of the current permission object and the specified permission object. This new permission object is a null reference (Nothing in Visual Basic) if the intersection is empty.
The target parameter is not a null reference (Nothing in Visual Basic) and is not an instance of the same class as the current permission object.
The intersection of two permissions is a permission that describes the set of operations they both describe. Only a demand that passes both original permissions will pass the intersection.
