How do I get the files from Directory in order in asp.net?

I'm getting the files from the Directory in asp.net using c# languages:

string[] array=Directory.GetFiles(Server.MapPath("Image"));

My Image folder has images like Image1.jpg, Image2.jpg, Image3.jpg........Image100.jpg.

My Issue is, I'm not getting the image files in order. How do I get the Image files in order say Image1 to Image100....

yea...I solved it myself..Here is the Solution:

var arr = (from u in Directory.GetFiles(Server.MapPath("Images")) let fi = new FileInfo(u) orderby fi.CreationTime select u);

This will work

 List<string> s = new List<string>();
 s.Add("image1.jpg");
 s.Add("image10.jpg");
 s.Add("image3.jpg");
 s.Add("image45.jpg");
 List<string> lst = s.OrderBy(x => int.Parse(x.Split('.')[0].Split(new string[] { "image" }, StringSplitOptions.None)[1])).ToList();

you can use linq like this: 

Directory.GetFiles(Server.MapPath("Image")).OrderBy(c => c.Name).ToList();

Try like this;

var images = from img in Directory.GetFiles(Server.MapPath("Image"))    
             orderby img descending 
             select img;

Or as an alternative, you can use OrderByDescending;

var images = Directory.EnumerateFiles(Server.MapPath("Image"))
                      .OrderByDescending(img => img);

Using LINQ OrderBy:

string[] array = Directory.GetFiles(Server.MapPath("Image"))
                          .OrderBy(x => x)
                          .ToArray();

or without LINQ, using Array.Sort method:

string[] array = Directory.GetFiles(Server.MapPath("Image"));
Array.Sort(array);

But it will sort using default string comparison, so Image100 will be before Image2.

It will be a bit more tricky to sort it using the number only, but you can do it with linq:

string[] array = (from f in Directory.GetFiles(Server.MapPath("Image"))
                  let n = int.Parse(f.Replace("Image", string.Empty).Replace(".jpg", string.Empty))
                  order by n
                  select f).ToArray();
