UrlIdentityPermission.IsSubsetOf Method (IPermission)
Determines whether the current permission is a subset of the specified permission.
Assembly: mscorlib (in mscorlib.dll)
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 Url property is not a valid URL.
The current permission is a subset of the specified permission if the current permission identifies access to a URL that is wholly contained by the specified permission. For example, a permission that represents access to http://www.fourthcoffee.com/process/grind.htm is a subset of a permission that represents access to http://www.fourthcoffee.com/*. If this method returns true, the current permission represents no more access to the protected resource than does the specified permission.
UrlIdentityPermission supports set operations ( , Intersect, and Union) only when the current permission is equal to the specified permission or when one of the permissions uses the wildcard operator ("*").
