ディレクトリ内情報取得

static void Main(string[] args)
{
    DirectoryInfo info = new DirectoryInfo(@"C:\msysgit\msysgit");
    foreach (var directory in info.GetDirectories())
        Console.WriteLine("Find : {0}", directory.Name);
    foreach (FileInfo file in info.GetFiles())
        Console.WriteLine("File : {0}", file.Name);
    Console.ReadLine();
}

結果は自分で試すべし。
