Examples
The following code example displays the subset relationship between two permissions.
static bool CheckSubSet(
SmtpPermission^ permission)
{
SmtpPermission^ allAccess =
gcnew SmtpPermission(PermissionState::Unrestricted);
return permission->IsSubsetOf(allAccess);
}
public static bool CheckSubSet(SmtpPermission permission)
{
SmtpPermission allAccess = new
SmtpPermission(System.Security.Permissions.PermissionState.Unrestricted);
return permission.IsSubsetOf(allAccess);
}
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. If this method returns true
, the current permission represents no more access to the protected resource than does the specified permission.
