When overridden in a derived class, creates a permission that is the union of the current permission and the specified permission.
[Visual Basic] Public Overridable Function Union( _ ByVal other As IPermission _ ) As IPermission Implements IPermission.Union [C#] public virtual IPermission Union( IPermission other ); [C++] public: virtual IPermission* Union( IPermission* other ); [JScript] public function Union( other : IPermission ) : IPermission;
- A permission to combine with the current permission. It must be of the same type as the current permission.
A new permission that represents the union of the current permission and the specified permission.
|NotSupportedException||The other parameter is not a null reference (Nothing in Visual Basic). This method is only supported at this level when passed a null reference (Nothing).|
The result of a call to Union 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.
Notes to Inheritors: You must implement this method in a derived class.
