Lambda code not working

[Jet Black]

I'm trying to look through a directory and pick every file that doesn't have a string at the beginning, and I am having a go at doing this with lambdas, but I am getting it wrong somewhere

Dim di As DirectoryInfo = New DirectoryInfo(My.Settings.str_TargetDir)
Dim fi_AllCSVfiles As FileInfo() = di.GetFiles("*.*", SearchOption.TopDirectoryOnly).Where(Function(x) (x.Name.StartsWith("ENCRYPTED_") = False))

There may be multiple errors in here that are causing me problems, can anyone point them out to me?

cheers!

damn I feel stupid, I just forgot .toarray at the end of the getfiles line.

Wait... doesn't GetFiles return an array? It does ... In fact, it's an array of FileInfo... so... why would you need the .ToArray on the end of that? *scratches head*
But, I guess if it works...

You are correct but he pipes that into a linq where clause which will return an IEnumerable(Of T).

Oooooh.... ok... he meant a .ToArry at the VERY END.... gotcha... I thought he had done it in the middle... I'm with ya now.

If you're going to use LINQ why not use EnumerateFiles? Can't imagine any performance difference but seems to fit better.

Imports System.IO
 
Public Class Form1
 
    Private Sub Foo()
        Dim di As New DirectoryInfo("path")
        Dim csvFiles = di.EnumerateFiles("path").Where(Function(fi) Not fi.Name.StartsWith("ENCRYPTED_"))
 
    End Sub
End Class
