C#从DirectoryInfo获得目录属性的代码

把开发过程中较好的一些内容段做个备份，下面的内容段是关于C#从DirectoryInfo获得目录属性的内容。

using System;

using System.IO;

class MainClass {

    static void Main(string[] args) {

        FileInfo file = new FileInfo("c:\a.txt");

        DirectoryInfo dir = file.Directory;

        Console.WriteLine("Checking directory: " + dir.Name);

        Console.WriteLine("In directory: " + dir.Name);

        Console.Write("Directory exists: ");

        Console.WriteLine(dir.Exists.ToString());

        if (dir.Exists) {

            Console.Write("Directory attribute list: ");

            Console.WriteLine(dir.Attributes.ToString());

        }

        Console.WriteLine();

    }

}
