Array initialisation values

[John Dann]

I want to populate a list box with the names of a set of files in a
particular folder with the same file type, so:

Dim MyArray as string = Directory.Getfiles(Path, ".etc")

But if the number of file names returned is zero, what state is the
array in and how can I test for this condition and distinguish it from
when just one file name is returned? (MyArray Is Nothing seems to be
False always)

Thanks

You can check the Length property on the array. If it's 0...

John,
try:
Dim MyArray() As String = Directory.GetFiles("", ".etc")
...and then
If MyArray.Length > 0 Then
... do something
End If
