要点：

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] Files = Directory.GetFiles(@"D:\xgc\1227\ASP.NET权限管理系统\frameworksrc20080415\20090219\FrameWork\Components", string.Format("*.{0}", "cs"));
            Console.WriteLine(Files.Length.ToString());
            foreach (string var in Files)
            {
                Console.WriteLine(var.ToLower());
            }
            Console.Read();
        }
    }
}

Get Files from Directory：

1，Method Directory.GetFiles returns string array with files names (full paths).

using System.IO;
string[] filePaths = Directory.GetFiles(@"c:\MyDir\");

2，Get files from directory (with specified extension)

string[] filePaths = Directory.GetFiles("c:\\MyDir", "*.bmp");

3,Get files from directory (including all subdirectories)

If you want to search also in subfolders use parameter SearchOption.A­llDirectories.

string[] filePaths = Directory.GetFiles(@"c:\MyDir\", "*.bmp",
                                         SearchOption.AllDirectories);
