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.Getfi les(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

Re: Array initialisation values

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

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