Determines whether the current permission is a subset of the specified permission.
Assembly: mscorlib (in mscorlib.dll)
- Type: System.Security.IPermission
A permission that is to be tested for the subset relationship. This permission must be of the same type as the current permission.
Return ValueType: System.Boolean
true if the current permission is a subset of the specified permission; otherwise, false.
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 set of operations 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.
