Determines whether the current permission object is a subset of the specified permission.
[Visual Basic] Overrides Public Function IsSubsetOf( _ ByVal target As IPermission _ ) As Boolean [C#] public override bool IsSubsetOf( IPermission target ); [C++] public: override bool IsSubsetOf( IPermission* target ); [JScript] public override function IsSubsetOf( target : IPermission ) : Boolean;
True if the target permission is a subset of the permission object, or false otherwise.
Exception Type | Condition |
---|---|
ArgumentException | if target is an object that is not of the same type as the current permission object. |
The current permission object is a safe subset of the specified permission object if the current permission object specifies a set of operations that is wholly contained by the specified permission object. For example, a permission that represents access to c:\foo.txt is a safe subset of a permission that represents access to c:\*.txt. If this method returns true, the current permission object represents no more access to the protected resource than target does.
