PeerCollaborationPermission.Intersect Method

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

Namespace:  System.Net.PeerToPeer.Collaboration
Assembly:  System.Net (in System.Net.dll)

public override IPermission Intersect(
	IPermission target
)

Parameters

target
Type: System.Security.IPermission
Permission to Intersect with the current permission. It must be of the same type as the current permission.

Return Value

Type: System.Security.IPermission
A new permission that represents the intersection of the current PeerCollaborationPermission and the specified target permission. This new permission is a null reference (Nothing in Visual Basic) if the intersection is empty.

Implements

IPermission.Intersect(IPermission)

ExceptionCondition
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) returns a null reference.
