Winform檔案夾內容同步更新、備份、日誌、恢複

標籤：c#   備份   

相信大家做項目或者處理檔案時候經常要用到備份的功能，這裡給大家做一個可以同步更新檔案夾內容並且備份的Winform程式，目前地址路徑在App.Config檔案裡面設定，如需更改直接用記事本編輯即可，下面放代碼和。

1.CS代碼：

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";//設定日誌地址        public AutoUpdate()        {            InitializeComponent();            this.txtFile.Text = filePath;            this.txtTo.Text = targetPath;

2.App.config檔案代碼：

<?xml version="1.0" encoding="utf-8" ?><configuration>  <appSettings>    <!--源地址-->    <add key="FilePath" value="C:\Users\xiaobai\Desktop\建立檔案夾"/>    <!--目標地址-->    <add key="TargetPath" value="D:\test\" />    <!--備份地址-->    <add key="backUpPath" value="D:\backup\" />    <!--設定定時時間-->    <add key="Timing" value="14:50" />  </appSettings></configuration>
