Creates and returns a permission that is the intersection of the current permission and the specified permission.
[Visual Basic] Function Intersect( _ ByVal target As IPermission _ ) As IPermission [C#] IPermission Intersect( IPermission target ); [C++] IPermission* Intersect( IPermission* target ); [JScript] function Intersect( target : IPermission ) : IPermission;
- A permission to intersect with the current permission. It must be of the same type as the current permission.
A new permission that represents the intersection of the current permission and the specified permission. This new permission is a null reference (Nothing in Visual Basic) if the intersection is empty.
|ArgumentException||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.|
The intersection of two permissions is a permission that describes the set of operations they both describe in common. Only a demand that passes both original permissions will pass the intersection.
The following statements are required to be true for all implementations of the Intersect method. X and Y represent IPermission object references that are not a null reference (Nothing in Visual Basic).
- X.Intersect(X) returns a value equal to X.
- X.Intersect(Y) returns the same value as Y.Intersect(X).
- X.Intersect(a null reference (Nothing)) returns a null reference (Nothing).
