public:
override bool IsSubsetOf(System::Security::IPermission ^ target);public override bool IsSubsetOf (System.Security.IPermission target);override this.IsSubsetOf : System.Security.IPermission -> boolPublic Overrides Function IsSubsetOf (target As IPermission) As BooleanParameters
- target
- IPermission
A permission that is to be tested for the subset relationship. This permission must be of the same type as the current permission.
Returns
true if the current permission is a subset of the specified permission; otherwise, false.
Exceptions
The target parameter is not null and is not of the same type as the current permission.
Remarks
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.
