Parameters

target

IPermission

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

Returns

IPermission

A new permission that represents the Union(IPermission) of the current PeerCollaborationPermission and the specified permission.

Exceptions

ArgumentException

The parameter is a null reference (Nothing in Visual Basic).

Remarks

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.

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

• X.Union(a null reference (Nothing in Visual Basic)) returns an object that has the same value as X.
