Assembly: mscorlib (in mscorlib.dll)
Parameters
- target
-
Type:

Return Value
Type: System::Booleantrue if the current permission is a subset of the specified permission; otherwise, false.
Implements
IPermission::IsSubsetOf(IPermission^)| Exception | Condition |
|---|---|
| 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 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.
The following code example shows the behavior of the IsSubsetOf method. This example is part of a larger example provided for the ReflectionPermission class.

The code example is intended to show the behavior of the method, not to demonstrate its use. In general, the methods of permission classes are used by the security infrastructure; they are not typically used in applications. |
