How can i sort the directories as they appear on my hard disk?

Question

On my hard disk i have for example:

dir1 dir2 dir3 dir4 .....

My code is :

DirectoryInfo dInfo = new DirectoryInfo(AutomaticsubDirectoryName);
DirectoryInfo[] subdirs = dInfo.GetDirectories();

so in subdirs i'm getting all the directories but they are not in the same order as they are on my hard disk. How can i sort them so they will be in subdirs in the same order they are on my hard disk ?

Solved it by this:

DirectoryInfo[] subdirs = dInfo.GetDirectories().OrderBy(d =>
                    {
                        int i = 0;
                        if (d.Name.Contains("Lightning ") && d.Name.Contains(" Length") && d.Name.IndexOf("Lightning ") < d.Name.IndexOf(" Length"))
                        {
                            string z = d.Name.Substring(("Lightning ").Length);
                            string f = z.Substring(0, z.IndexOf(" Length"));
                            if (Int32.TryParse(f, out i))
                                return i;
                            else
                                return -1;
                        }
                        else
                            return -1;
                    }).ToArray();

Working perfect.

Answer 1

Assuming you are talking about filesystems and how a software like Windows Explorer displays the names, I suppose you are talking about natural sorting the names. Read here: http://www.codinghorror.com/blog/2007/12/sorting-for-humans-natural-sort-order.html

Craetion time是合理的标准，它们如何出现在硬盘上。

DirectoryInfo[] subdirs = dInfo.GetDirectories().OrderBy(d => d.CreationTime).ToArray();

Answer 3

The string compare function that Windows uses is exposed for everybody to use. So you'll need a wee bit of pinvoke to get the exact same sort order as Explorer uses. Wrapping it in an IComparer<> so you can just pass it to Array.Sort() or an OrderBy() Linq clause:

using System;
using System.Collections.Generic;
using System.Runtime.InteropServices;

public class LogicalComparer : IComparer<string> {
    public int Compare(string x, string y) {
        return StrCmpLogicalW(x, y);
    }
    [DllImport("shlwapi.dll", CharSet = CharSet.Unicode, ExactSpelling = true)]
    private static extern int StrCmpLogicalW(string s1, string s2);
}

                        if (d.Name.Contains("Lightning ") && d.Name.Contains(" Length") && d.Name.IndexOf("Lightning ") < d.Name.IndexOf(" Length"))
                        {
                            string z = d.Name.Substring(("Lightning ").Length);
                            string f = z.Substring(0, z.IndexOf(" Length"));
                            if (Int32.TryParse(f, out i))
                                return i;
                            else
                                return -1;
                        }
                        else
                            return -1;
                    }).ToArray();
