handing the OnCreated event of FileSystemWatcher

Question

I implemented this event of the FileSystemWatcher:

Private Shared Sub OnCreated(source As Object, e As FileSystemEventArgs)
    If e.Name.ToUpper() == "MYTEXTFILE.TXT" then
        ' code '
    End If
End Sub

Is there a way to monitor if created files are in a textbox similar to this?

Private Shared Sub OnCreated(source As Object, e As FileSystemEventArgs)
    If e.Name.ToUpper.contains(textbox1.text) then
          ' code '
End Sub

Having more than one file in a multiline textbox and every filename is in a separate line requires that you should split the filenames individually and then check each one with the file just created.

Private Shared Sub OnCreated(source As Object, e As FileSystemEventArgs)

    ' Get an array of the files at each line and remove eventually spurious empty lines
    Dim files() = textbox1.Text.Split(New String() {Environment.NewLine}, _
                                      StringSplitOptions.RemoveEmptyEntries)
    Dim newFile = e.Name.ToUpper()
    for each file in files
        if file.ToUpper() = newFile Then
            ' code '
            Exit For
        End If
    Next
End Sub
