通過調用MySql的工具mysqldump來實現。
類Cmd來實現調用cmd命令,
要啟動的進程所在的目錄是說mysql自動的備份還原資料庫工具mysqldump和mysql所在目錄,當然,這個方法可以執行別的命令列工具。
using System;
using System.Collections.Generic;
using System.Text;
using System.Diagnostics;
public class Cmd
{
/// <summary>
/// 執行Cmd命令
/// </summary>
/// <param name="workingDirectory">要啟動的進程的目錄</param>
/// <param name="command">要執行的命令</param>
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");
}
}
備份方法:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Diagnostics;
using System.Configuration;
using MDRClient.DataAccess;
namespace MDRClient
{
public partial class DataBackup : Form
{
public DataBackup()
{
InitializeComponent();
}
private void btnBackup_Click(object sender, EventArgs e)
{
try
{
//String command = "mysqldump --quick --host=localhost --default- character-set=gb2312 --lock-tables --verbose --force --port=連接埠號碼 --user= 使用者名稱 --password=密碼 資料庫名 -r 備份到的地址";
//構建執行的命令
StringBuilder sbcommand = new StringBuilder();
StringBuilder sbfileName = new StringBuilder();
sbfileName.AppendFormat("{0}", DateTime.Now.ToString()).Replace("-", "").Replace(":", "").Replace(" ", "");
String fileName = sbfileName.ToString();
SaveFileDialog saveFileDialog = new SaveFileDialog();
saveFileDialog.AddExtension = false;
saveFileDialog.CheckFileExists = false;
saveFileDialog.CheckPathExists = false;
saveFileDialog.FileName = fileName;
if (saveFileDialog.ShowDialog() == DialogResult.OK)
{
String directory = saveFileDialog.FileName;
sbcommand.AppendFormat("mysqldump --quick --host=localhost --default- character-set=gbk --lock-tables --verbose --force --port=連接埠號碼 --user=使用者 名 --password=密碼 資料庫名 -r \"{0}\"", directory);
String command = sbcommand.ToString();
//擷取mysqldump.exe所在路徑
String appDirecroty = System.Windows.Forms.Application.StartupPath + "\\";
Cmd.StartCmd(appDirecroty, command);
MessageBox.Show(@"資料庫已成功備份到 " + directory + " 檔案中", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
catch (Exception ex)
{
MessageBox.Show("Database Backup失敗!");
}
}
}
}
還原方法,調用的是mysql內建工具mysql,還原時要注意的是選擇的檔案所在路徑時,檔案名稱要是有空格的話會出
異常,所以在檔案路徑名加上雙引號""
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Diagnostics;
using System.Configuration;
using MDRClient.DataAccess;
namespace MDRClient
{
public partial class DataRestore : Form
{
public DataRestore()
{
InitializeComponent();
}
private void btnRestore_Click(object sender, EventArgs e)
{
//string s = "mysql --port=連接埠號碼 --user=使用者 名 --password=密碼 資料庫名<還原檔案所在路徑";
try
{
StringBuilder sbcommand = new StringBuilder();
OpenFileDialog openFileDialog = new OpenFileDialog();
if (openFileDialog.ShowDialog() == DialogResult.OK)
{
String directory = openFileDialog.FileName;
//在檔案路徑後面加上""避免空格出現異常
sbcommand.AppendFormat("mysql --host=localhost --default-character-set=gbk --port=連接埠 號 --user=使用者名稱 --password=密碼 資料庫<\"{0}\"", directory);
String command = sbcommand.ToString();
//擷取mysql.exe所在路徑
String appDirecroty = System.Windows.Forms.Application.StartupPath + "\\";
DialogResult result = MessageBox.Show("您是否真的想覆蓋以前的資料庫嗎?那麼以前的資料庫資料將丟失!!!", "警告", MessageBoxButtons.YesNo, MessageBoxIcon.Warning);
if (result == DialogResult.Yes)
{
Cmd.StartCmd(appDirecroty, command);
MessageBox.Show("資料庫還原成功!");
}
}
}
catch (Exception ex)
{
MessageBox.Show("資料庫還原失敗!");
}
}
}
}
