.Net笔记:System.IO之windows文件操作的深入分析

复制代码 代码如下:

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

namespace aboutio
{
    class Program
    {
        static void Main(string[] args)
        {
            DriveInfo[] drives = DriveInfo.GetDrives();

            foreach (DriveInfo drive in drives)
            {
                if(drive.IsReady)
                    Console.WriteLine("类型：{0} 卷标：{1} 名称：{2} 总空间：{3} 剩余空间：{4}",drive.DriveType, drive.VolumeLabel,drive.Name,drive.TotalSize,drive.TotalFreeSpace);
                else
                    Console.WriteLine("类型：{0}  is not ready",drive.DriveType);
            }

            Console.ReadLine();
        }
    }
}

复制代码 代码如下:

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

namespace UseFileSystemWatcher
{
    class Program
    {
        static void Main(string[] args)
        {
            //声明要监视的目录
            string watchPath = "D://watch";
            FileSystemWatcher watcher = new FileSystemWatcher(watchPath, "*.*");
            //添加文件变化处理事件
            watcher.Changed += new FileSystemEventHandler(Watcher_Changed);
            //添加文件创建处理事件
            watcher.Created += new FileSystemEventHandler(Watcher_Created);
            //添加文件删除处理事件
            watcher.Deleted += new FileSystemEventHandler(Watcher_Deleted);          
            //添加错误处理
            watcher.Error += new ErrorEventHandler(Watcher_Error);
            //启动监视
            watcher.EnableRaisingEvents = true;
            Thread.Sleep(1000 * 60);
            Console.WriteLine("press any key to exit..");
            Console.Read();
        }

        static void Watcher_Error(object sender, ErrorEventArgs e)
        {
            Console.WriteLine("错误：" + e.ToString());
        }

        static void Watcher_Deleted(object sender, FileSystemEventArgs e)
        {
            Console.WriteLine(e.ChangeType + ":" + e.FullPath);
        }

        static void Watcher_Created(object sender, FileSystemEventArgs e)
        {
            Console.WriteLine(e.ChangeType + ":" + e.FullPath);
        }

        static void Watcher_Changed(object sender, FileSystemEventArgs e)
