The result of a call to Union is a permission that represents all the operations represented by both the current PeerCollaborationPermission and the specified permission. Any demand that passes either permission passes their union.

The following statements are required to be true for all implementations of the Union method. X and Y represent IPermission objects that are not a null reference (Nothing in Visual Basic).

  • X.Union(X) returns an object that has the same value as X.
