相信大家做项目或者处理文件时候经常要用到备份的功能，这里给大家做一个可以同步更新文件夹内容并且备份的Winform程序，目前地址路径在App.Config文件里面设置，如需更改直接用记事本编辑即可，下面放代码和截图。

1.CS代码：

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using System.IO;using System.Configuration;using System.Text.RegularExpressions;namespace Update{    public partial class AutoUpdate : Form    {        string filePath = ConfigurationManager.AppSettings["FilePath"].ToString();        string targetPath = ConfigurationManager.AppSettings["TargetPath"].ToString();        string Timing = ConfigurationManager.AppSettings["Timing"].ToString();        string backPath = ConfigurationManager.AppSettings["backUpPath"].ToString();        int count = 0;        string fullPath = "D:/backup/backup.txt";//设置日志地址        public AutoUpdate()        {            InitializeComponent();            this.txtFile.Text = filePath;            this.txtTo.Text = targetPath;            this.txtTime.Text = Timing;        }        /// <summary>        /// 更新        /// </summary>        /// <param name="sender"></param>        /// <param name="e"></param>        private void btnUpdate_Click(object sender, EventArgs e)        {            //更新同时调用备份            backup();            if (filePath != "")            {                if (CopyDir(filePath, targetPath))                {                    MessageBox.Show("更新成功！！！");                }                else                {                    MessageBox.Show("更新失败！！！");                }            }            else            {                MessageBox.Show("请正确设置源地址!");            }        }        /// <summary>        /// 更新文件处理        /// </summary>        /// <param name="srcPath"></param>        /// <param name="aimPath"></param>        /// <returns></returns>        private bool CopyDir(string srcPath, string aimPath)        {            bool copyFile = false;

               }                // 判断目标目录是否存在如果不存在则新建                 if (!System.IO.Directory.Exists(aimPath))                {                    System.IO.Directory.CreateDirectory(aimPath);                }                // 得到源目录的文件列表，该里面是包含文件以及目录路径的一个数组                 // 如果你指向copy目标文件下面的文件而不包含目录请使用下面的方法                 // string[] fileList = Directory.GetFiles（srcPath）；                 string[] fileList = System.IO.Directory.GetFileSystemEntries(srcPath);                string str = "";                if (count == 0)                {                    str = DateTime.Now.ToString() + "------";                }                // 遍历所有的文件和目录                 foreach (string file in fileList)                {                    // 先当作目录处理如果存在这个目录就递归Copy该目录下面的文件                     if (System.IO.Directory.Exists(file))                    {                        CopyDir(file, aimPath + System.IO.Path.GetFileName(file));

                   }                }                else                {                    File.Create(fullPath).Close();                    using (StreamWriter sw = new StreamWriter(fullPath, true, Encoding.Default))                    {                        sw.WriteLine(str);

2.App.config文件代码：

<?xml version="1.0" encoding="utf-8" ?><configuration>  <appSettings>    <!--源地址-->    <add key="FilePath" value="C:\Users\xiaobai\Desktop\新建文件夹"/>    <!--目标地址-->    <add key="TargetPath" value="D:\test\" />    <!--备份地址-->    <add key="backUpPath" value="D:\backup\" />    <!--设置定时时间-->    <add key="Timing" value="14:50" />  </appSettings></configuration>
