Question

i have folder that contain image files which named with number 1,2,3…
how do i read the image file name in sequence starting with 1 until the end(whatever number it is).

Answer 1

You may use OrderBy on file array.

DirectoryInfo dir = new DirectoryInfo(@"C:\yourfolder");
FileInfo[] files = dir.GetFiles();
//User Enumerable.OrderBy to sort the files array and get a new array of sorted files
FileInfo[] sortedFiles = files.OrderBy(r => r.Name).ToArray();

For File number with just numeric(int) names try:

FileInfo[] sortedFiles = files
                          .OrderBy(r => int.Parse(Path.GetFileNameWithoutExtension(r.Name)))
                          .ToArray();
