为了方便直观的体现操作方法，先在前台页面上建立几个按纽和labels标签，如下所示：

后台页面：
using ...System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;
public partial
class _Default : System.Web.UI.Page
...{
protected void Page_Load(object sender, EventArgs e)
...{
}
//在aspxcs.txt文件里写入内容
protected void addFile_OnClick(object sender, EventArgs e)
...{
StreamWriter sw = File.AppendText(Server.MapPath(".") + "\\aspxcs.txt");
sw.Write(""+write.Text.Trim()+"");//写入内容到aspxcs.txt文件里
sw.Flush();
sw.Close();
lab.Text = "内容写入成功!";
}
//拷贝aspxcs.txt文件为aspxcsnet.txt
protected void copyFile_OnClick(object sender, EventArgs e)
...{
string OldFile, NewFile;
OldFile = Server.MapPath(".") + "\\aspxcs.txt";
NewFile = Server.MapPath(".") + "\\aspxcsnet.txt";
File.Copy(OldFile, NewFile, true);
lab2.Text = "拷贝成功";
}
//删除aspxcsnet.txt文件
protected void delFile_OnClick(object sender, EventArgs e)
...{
string delFile = Server.MapPath(".") + "\\aspxcsnet.txt";
File.Delete(delFile);
lab3.Text = "删除成功!";
}
//移动文件
protected void moveFile_OnClick(object sender, EventArgs e)
...{
string OldFile, NewFile;
OldFile = Server.MapPath(".") + "\\aspxcs.txt";
NewFile = Server.MapPath(".") + "\\MyFile.txt";
File.Move(OldFile, NewFile);
lab4.Text = "移动成功";
}
//创建目录
protected void creatFile_OnClick(object sender, EventArgs e)
...{
DirectoryInfo d = Directory.CreateDirectory("c:\\sixAge"); // 创建目录c:\sixAge
DirectoryInfo d1 = d.CreateSubdirectory("sixAge1"); // d1指向c:\sixAge\sixAge1
DirectoryInfo d2 = d1.CreateSubdirectory("sixAge1_1"); //. CreateSubdirectory在指定路徑中創建一個或多個子目錄。 d2指向c:\sixAge\sixAge1\sixAge1_1
Directory.SetCurrentDirectory("c:\\sixAge"); //.SetCurrentDirectory將應用程序的當前目錄設置成指定目錄。 将当前目录设为c:\sixAge
Directory.CreateDirectory("sixAge2");// 创建目录c:\sixAge\sixAge2
Directory.CreateDirectory("sixAge2\\sixAge2_1"); //创建目录c:\sixAge\sixAge2\sixAge2_1
lab5.Text = "创建成功";
}
}
以上方法只是简单的运用，希望能对你有所帮助，可直接复制代码运行测试！
