)

Parameters

target
Type: System.Security.IPermission

A permission object to intersect with the current permission object. It must be of the same type as the current permission object.

Return Value

Type: 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.

Implements

IPermission.Intersect(IPermission)

ExceptionCondition
ArgumentException

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.
