自己编写一个小病毒代码

C# 代码

自己编写一个小程序，类是病毒但无害，就是会创建50*50*26个空文件夹，运行过产生30000个文件夹就等不下去了，删除新建的文件夹估计要10分钟，仅为娱乐

private void button4_Click(object sender, EventArgs e)

{

IList temp_list = new List();

string path = "I:\\新建文件夹";/****本人笔记本有I盘，同时为了删除方便****/

// string path = "C:\\Program Files"; 用这行代码时估计你要崩溃

string pathFile = "";

char [] arry = new char[26]

{'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z' };

try

{

for (int p = 0; p < 50; p++)

{

for (int k = 0; k < 50; k++)

{

for (int i = 0; i < 26; i++)

{

temp_list.Add(i.ToString());

//temp_list.Add("num:" + i.ToString());

}

temp_list = getListItems(temp_list, 26);

for (int i = 0; i < temp_list.Count; i++)

{

richTextBox1.Text += arry[int.Parse(temp_list[i])];

pathFile += arry[int.Parse(temp_list[i])];

if (Directory.Exists(path + "\\" + pathFile))/***判断文件夹是否存在，存在就删除该文件加***/

{

Directory.Delete(path + "\\" + pathFile);

System.IO.Directory.CreateDirectory(path + "\\" + pathFile);/****创建文件加*****/

}

else

{

System.IO.Directory.CreateDirectory(path + "\\" + pathFile); /****创建文件加*****/

}

richTextBox2.Text += temp_list[i];

if (pathFile.Length > 200)/***文件夹的名字超过240字符后会报错，故取240以内都有效***/

{

pathFile = "";

}

}

}

}

}

catch (Exception ee)

{

throw new Exception(ee.ToString());

}

}

public static IList getListItems(IList list, int num)/***建立获取随机数****/

{

IList temp_list = new List(list);

IList return_list = new List();

Random random = new Random();

for (int i = 0; i < num; i++)

{

if (temp_list.Count > 0)

{

int arrIndex = random.Next(0, temp_list.Count);

return_list.Add(temp_list[arrIndex]);

temp_list.RemoveAt(arrIndex);

}

else

{

break;

}

}

return return_list;

}
