PnrpPermission.Intersect(IPermission) Method

Definition

Creates and returns a permission that is the intersection of the current PnrpPermission and the specified permission.

public:
 override System::Security::IPermission ^ Intersect(System::Security::IPermission ^ target);
public override System.Security.IPermission Intersect (System.Security.IPermission target);
override this.Intersect : System.Security.IPermission -> System.Security.IPermission
Public Overrides Function Intersect (target As IPermission) As IPermission

Parameters

target
IPermission

A permission to Intersect(IPermission) 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 PnrpPermission and the specified permission. This new permission is a null reference (Nothing in Visual Basic) if the intersection is empty.

Exceptions

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.

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 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 in Visual Basic)) returns a null reference (Nothing in Visual Basic).
