为了确保数据的安全，我们往往要对数据进行备份。但是为了减少我们的工作量，我写了一个简单的数据备份工具，实现定时备份数据库。
其实程序很简单，数据备份的工作就是几个mysql的命令而已。
先看看程序的运行界面
可以看到界面是十分的简单的
我们使用的是命令行来进行数据备份，所以我们的程序需要一个能够执行命令行的函数
/// <summary>
/// 执行Cmd命令
/// </summary>
/// <param name="workingDirectory">要启动的进程的目录
/// <param name="command">要执行的命令
public static void StartCmd(String workingDirectory, String command)
{
Process p = new Process();
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.WorkingDirectory = workingDirectory;
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.CreateNoWindow = true;
p.Start();
p.StandardInput.WriteLine(command);
p.StandardInput.WriteLine("exit");
}public void bakup_db()
{
try
{
//String command = "mysqldump --quick --host=localhost --default-character-set=gb2312 --lock-tables --verbose --force --port=端口号 --user=用户名 --password=密码 数据库名 -r 备份到的地址";
//构建执行的命令
StringBuilder sbcommand = new StringBuilder();
StringBuilder sbfileName = new StringBuilder();
sbfileName.AppendFormat("{0}", DateTime.Now.ToShortDateString()).Replace("-", "").Replace(":", "").Replace(" ", "").Replace("/", "");
String fileName = sbfileName.ToString();
String directory = bakpath + fileName+".bak";
sbcommand.AppendFormat("mysqldump --quick --host=localhost --default-character-set=utf8 --lock-tables --verbose --force --port=3306 --user={0} --password={1} {2} -r \"{3}\"", uname, upass, dbname, directory);
String command = sbcommand.ToString();
//获取mysqldump.exe所在路径
//String appDirecroty = System.Windows.Forms.Application.StartupPath + "\\";
StartCmd(appDirecroty, command);
}
catch (Exception ex)
{
}
} public void recovery_db()
{
//string s = "mysql --port=端口号 --user=用户名 --password=密码 数据库名<br>
为了实现定时备份，我们使用的是一个Timer组件，来实现定时的数据备份
<pre class="brush:php;toolbar:false">private void timer1_Tick(object sender, EventArgs e)
{
int h = DateTime.Now.Hour;
if (h == hour)
{
bakup_db();
}
}using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;
namespace MysqlBak
{
public partial class Form1 : Form
{
//备份文件的路径
public String bakpath="d:\\db_bak\\";
public String appDirecroty = @"C:\Program Files (x86)\MySQL\MySQL Server 6.0\bin";
public String uname = "root";
public String upass = "root";
public String dbname = "losscar_db";
