IPermission::IsSubsetOf(IPermission^)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. 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 displays the subset relationship between two permissions.
System::Net::NetworkInformation::NetworkInformationPermission^ unrestricted = gcnew System::Net::NetworkInformation::NetworkInformationPermission( System::Security::Permissions::PermissionState::Unrestricted ); Console::WriteLine( L"Is unrestricted? {0}", unrestricted->IsUnrestricted() ); System::Net::NetworkInformation::NetworkInformationPermission^ read = gcnew System::Net::NetworkInformation::NetworkInformationPermission( System::Net::NetworkInformation::NetworkInformationAccess::Read ); System::Net::NetworkInformation::NetworkInformationPermission^ copyPermission = dynamic_cast<System::Net::NetworkInformation::NetworkInformationPermission^>(read->Copy()); System::Net::NetworkInformation::NetworkInformationPermission^ unionPermission = dynamic_cast<System::Net::NetworkInformation::NetworkInformationPermission^>(read->Union( unrestricted )); Console::WriteLine( L"Is subset?{0}", read->IsSubsetOf( unionPermission ) );
