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>

private void btnUpdate_Click(object sender, EventArgs e)

//更新同时调用备份
backup();

if (CopyDir(filePath, targetPath))
{
MessageBox.Show("更新成功！！！");
}
else
{
MessageBox.Show("更新失败！！！");
}

MessageBox.Show("请正确设置源地址!");
}

}
// 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));
if (count == 0)
{
str += file + ",";
}
}
// 否则直接Copy文件
else
{
System.IO.File.Copy(file, aimPath + System.IO.Path.GetFileName(file), true);
if (count == 0)
{
str += file + ",";
}
}
}
if (System.IO.File.Exists(fullPath))
{
using (StreamWriter sw = new StreamWriter(fullPath, true, Encoding.Default))
{
sw.WriteLine(str);
}
}
else

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>
