用C#.NET实现删除指定文件
using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
namespace DeleteFile
{
class Program
{
public static void DeleteFile(string dirRoot)
{
string deleteFileName = "_desktop.ini";//要删除的文件名称
try
{
string[] rootDirs = Directory.GetDirectories(dirRoot); //当前目录的子目录：
string[] rootFiles = Directory.GetFiles(dirRoot); //当前目录下的文件：
foreach (string s2 in rootFiles)
{
if (s2.Contains(deleteFileName))
{
Console.WriteLine(s2);
File.Delete(s2); //删除文件
}
}
foreach (string s1 in rootDirs)
{
DeleteFile(s1);
}
}
catch(Exception ex)
{
Console.WriteLine(ex.Message.ToString());
}
}
static void Main(string[] args)
{
string[] drives = Directory.GetLogicalDrives();//系统所有根目录
foreach (string s in drives)
{
DeleteFile(s);
}
Console.WriteLine("Delete Files Complete!");
Console.ReadLine();
}
}
}

另一种方法：
/// <summary>
/// 删除指定文件夹，文件
/// </summary>
/// <param name="dir"></param>
public static void DeleteFolder(string dir)
{
foreach (string d in Directory.GetFileSystemEntries(dir))
{
if (File.Exists(d))
{
FileInfo fi = new FileInfo(d);
if (fi.Attributes.ToString().IndexOf("ReadOnly") != -1)
fi.Attributes = FileAttributes.Normal;
File.Delete(d);//直接删除其中的文件
}
else
DeleteFolder(d);//递归删除子文件夹
}
Directory.Delete(dir);//删除已空文件夹
}
