public:
 override System::Security::IPermission ^ Union(System::Security::IPermission ^ target);

public override System.Security.IPermission Union (System.Security.IPermission target);

override this.Union : System.Security.IPermission -> System.Security.IPermission

Public Overrides Function Union (target As IPermission) As IPermission

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 of the current permission and the specified permission.

Exceptions

ArgumentException

The target parameter is not null and is not of the same type as the current permission.

-or-

The two permissions are not equal.

Remarks

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

The PublisherIdentityPermission class only supports set operations (IsSubsetOf, Intersect, and Union) when the current permission is equal to the specified permission.
