          <see cref="T:System.ArgumentNullException" /> behaves identically to <see cref="T:System.ArgumentException" />. It is provided so that 
   application code can differentiate between exceptions caused by
<see langword="null" /> 
arguments and exceptions caused by non-null arguments. For errors caused by
non-null arguments, see <see cref="T:System.ArgumentOutOfRangeException" />
