Directory.getFilesで数値順でのソートができません。

Apr 30, 2015

dirNow = "C:\car";
fileNames[0] = "C:\car\1.txt";
fileNames[1] = "C:\car\2.txt";
fileNames[2] = "C:\car\3.txt";
fileNames[3] = "C:\car\10.txt";


string[] fileNames = Directory.GetFiles(dirNow);
Array.Sort(fileNames);
foreach(string str in fileNames) Console.WriteLine(str);
Application.Exit();

結果

1.txt
10.txt
2.txt
3.txt

理想

1.txt
2.txt
3.txt
10.txt
