如何区分没有扩展名的文件夹和文件？

Question

I am trying to distinguish files without this extension from folders, how to distinguish them from each other in VB NET. I have to differentiate them for logging. File without extension generated from excel file modification, like this..

Answer 1

You can use something like this:

Dim filesWithOutExtension As List(Of String) = IO.Directory.GetFiles("C:\Users\UserName\Documents\").Where(Function(el) New IO.FileInfo(el).Extension.Length = 0).ToList

Answer 2

There is a 2'nd parameter to GetFiles called searchPattern where you can specify "*." .

Dim filesWithoutExtension = System.IO.Directory.GetFiles("c:\temp\", "*.")
