I have an Tuple List and I'm filling this list with all directorys of an folder and bind it to an asp:ListView with this code:

List<string> directoryContent = new List<string>(Directory.GetFileSystemEntries(dirPath);
List<Tuple<string, string>> directoryList = new List<Tuple<string, string>>();

for (int i = 0; i < directoryContent.Count; i++)

 FileAttributes attr = File.GetAttributes(directoryContent[i]);
 if (attr.ToString().Equals("Directory"))
 
 String str = directoryContent[i].Remove(0, dirPath.Length);
 string count = Directory.GetFiles(directoryContent[i], "*.*", SearchOption.AllDirectories).Length.ToString();
 directoryList.Add(new Tuple<string, string>(str, count));
 


directoryListView.DataSource = directoryList;
directoryListView.DataBind();

For example the found directories are

• 12


• 566


• 10001


• 10


• templates


• files

What would be the best way to sort the List or the ListView in this way? Thank you in advance.
I need to sort the directory that they are sorted in this order:

• files


• templates


• 10


• 12


• 566


• 1001

You can use Linq for that.

//test data
List<string> list = new List<string>()

 "12",
 "566",
 "10001",
 "10",
 "templates",
 "files"
;

int tempInt;

//filter the numbers from the list and sort
var listNumbers = list.Where(x => int.TryParse(x, out tempInt)).Select(y => Convert.ToInt32(y)).OrderBy(z => z);

//filter the strings from the list and sort
var listStrings = list.Where(x => !int.TryParse(x, out tempInt)).OrderBy(y => y);

//join the two lists again
var orderedList = listStrings.Concat(listNumbers.Select(y => y.ToString())).ToList();

Update for Tuple List

List<Tuple<string, string>> list = new List<Tuple<string, string>>()

 new Tuple<string, string>("12", "NA"),
 new Tuple<string, string>("566", "NA"),
 new Tuple<string, string>("10001", "NA"),
 new Tuple<string, string>("10", "NA"),
 new Tuple<string, string>("templates", "NA"),
 new Tuple<string, string>("files", "NA")
;

int tempInt;

//filter the numbers from the list and sort
var listNumbers = list.Where(x => int.TryParse(x.Item1, out tempInt)).Select(y => new Tuple<int, string>(Convert.ToInt32(y.Item1), y.Item2)).OrderBy(z => z.Item1);

//filter the strings from the list and sort
var listStrings = list.Where(x => !int.TryParse(x.Item1, out tempInt)).OrderBy(z => z.Item1);

//join the two lists again
var orderedList = listStrings.Concat(listNumbers.Select(y => new Tuple<string, string>(y.Item1.ToString(), y.Item2))).ToList();
