Determines whether the current instance is a subset of the specified object.
- target
- A System.Net.WebPermission instance that is to be tested for the subset relationship.
true if the current instance is a subset of target ; otherwise, false. If target is null, return false. If the current instance is unrestricted, and target is not, returns false. If target is unrestricted, returns true.
Type Reason ArgumentException target is not of type System.Net.WebPermission.
Note:The current instance is a subset of target if the current instance specifies a set of accesses to resources that is wholly contained by target. For example, a permission that represents read access to a file is a subset of a permission that represents read and write access to the file.
If this method returns true , the current instance describes access to internet resources that is also described by target .
This method overrides System.Security.CodeAccessPermission.IsSubsetOf(System.Security.IPermission) and is implemented to support the System.Security.IPermission interface.
