vb.Net delete files with specific extension

Try using something like this:

Dim files as String() = System.IO.Directory.GetFiles(path, "*.txt");

This command retrieves a string array of files for a given extension from the requested folder path.

i would replace:

 Dim di As New System.IO.DirectoryInfo(strPath)
Dim files As New List(Of System.IO.FileInfo)
files.AddRange(di.GetFiles())

Select allOpen in new window

with:

Dim files As New List(Of System.IO.FileInfo)
files.AddRange(System.IO.Directory.GetFiles(strPath, "*.txt"))

Select allOpen in new window
