|---|---|
| ArgumentException | The target parameter is not null and is not of the same type as the current permission. |
The current permission is a subset of the specified permission if the current permission specifies a state that is wholly contained by the specified permission. For example, a permission that represents access to C:\example.txt is a subset of a permission that represents access to C:\. If this method returns true, the current permission represents no more access to the protected resource than does the specified permission.
