System.ArgumentNullException
 Subclass of ArgumentException that's thrown when a function argument is null.
System.ArgumentOutOfRangeException
 Subclass of ArgumentException that's thrown when an argument is too big or too small.
System.InvalidOperationException

System.NotSupportedException

System.NotImplementedException
