How to indentify a specific VB.Net error ?

In VB 6, I can use the err.number to get the error's number and write code to handle that specific error.
but in VB.NET, how can i identify exactly what error is happening ?

and one more question, what is the differences between compiling a project or solution with debug mode and realease mode ?

Thanks,

Phat

Errors in VB.NET are called Exceptions.  To trap an Exception, you use a Try...Catch construction.  Sample code is below.

---Code Start---

Module Module1

   Sub Main()
      Dim x, y, z As Integer
      x = 100
      y = 0
      Try
         z = x / y
      Catch e As Exception
         Console.WriteLine(e.Message())
         Console.WriteLine(e.GetType())
      End Try

   End Sub ' Main

End Module ' Module1

--- Code End ---

The output of the following code is:
   Arithmetic operation resulted in an overflow.
   System.OverflowException

So when you talk about getting the error number, I think in .NET-speak, you want to retrieve the Type of the exception.
