array question

Hi,

I use:

 

Dim MyArray() As String = = EmailMessage.GetHeaderField("Disposition-Notification-To")

 

EmailMessage is a 3rd party component, now it may or may not have anything, so the array is null/nothing in that case.

In that case, any operation on array will return System.NullReferenceException

Even if I want to check if the array :

 

If MyArray IsNot Nothing

or

If MyArray.Length = 0

 

All will result in System.NullReferenceException

How to check such an array at all?

Thanks.

First, get rid of the double equals (==). That is 'C' syntax.

 

Next, have you tried the logic backwards and using parenthesis?

 

If (MyArray Is Nothing) Then
 Return
End If
