DirectoryInfo对比Directory

Directory 与 DirectoryInfo 区别

前者继承System.Object,后者继承抽象类FileSystemInfo

前者是静态类，后者是非静态类，需要new创建实例

前者返回的类型是简单字符串，后者返回的是强类型如FileInfo

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

namespace DirectoryInfo对象
{
    class Program
    {
        static void Main(string[] args)
        {
            ShowWindowsDirectoryInfo();
        }
        static void ShowWindowsDirectoryInfo()
        {
            DirectoryInfo dir = new DirectoryInfo(@"G:\c#");
            //获取所有文件
            FileInfo [] files = dir.GetFiles("*.png",SearchOption.AllDirectories);
            Console.WriteLine("************以下是文件信息**************");
            foreach (FileInfo f in files)
            {
                Console.WriteLine("FileName:{0}",f.Name);
                Console.WriteLine("FullName:{0}",f.FullName);
            }
            Console.WriteLine("****************以下是目录信息*****************");
            Console.WriteLine("FullName:{0}",dir.FullName);
            Console.WriteLine("Name:{0}",dir.Name);
            Console.WriteLine("Creation:{0}",dir.CreationTime);
            Console.WriteLine("Attributes:{0}",dir.Attributes);
            Console.WriteLine("Root:{0}",dir.Root);
        }
    }
}
