Syntax

public IPermission Intersect (IPermission target)

Parameters

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

Returns

A new permission that represents the intersection of the current permission and the specified permission. This new permission is null if the intersection is empty.

Exceptions

ArgumentException target is not null and is not of the same type as the current instance.

Remarks

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 IPermission.Intersect(IPermission) method. X and Y represent System.Security.IPermission object references that are not null.

X.Intersect(X) returns a value equal to X.
X.Intersect(Y) returns the same value as Y.Intersect(X).
X.Intersect(null) returns null.
