Is anybody aware of these two keywords OrElse and AndAlso in Vb.Net.

These keywords were introduced in .Net 2.0 . 

 Dim myobj As Object
 If Not IsNothing(myobj) AndAlso myobj.y = 200 Then
 Console.WriteLine("Hello World")
End If

If the myObj is null or nothing then the If condition  shortcircuits and will not validate the condition myObj.y=200 .

I would advise everybody to use the  andAlso and orElse.  I wonder why it was not introduced  a long time back.

C# by default had this feature  by the use && and ||.
