c#mysql数据库备份还原

引用dll

MySql.Data.dll, MySqlbackup.dll

建静态类

public static class mysql
{
public static string constr = "database=test;Password=密码;user ID=root;server=ip地址";
public static MySqlConnection conn = new MySqlConnection(constr);
}

备份代码

DialogResult result = MessageBox.Show("备份路径默认在当前程序下", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
if (result == DialogResult.Yes) 
{
	string time1 = System.DateTime.Now.ToString("d").Replace("/", "-");
	string file = ".//mysql/" + time1 + "_test.sql";
	using (MySqlCommand cmd = new MySqlCommand()) 
	{
		using (MySqlBackup mb = new MySqlBackup(cmd)) 
		{
			cmd.Connection = mysql.conn;
			mysql.conn.Open();
			mb.ExportToFile(file);
			mysql.conn.Close();
			MessageBox.Show("已备份");
		}
	}
} else 
{
	return;
}

还原代码

string file = textBox1.Text;
if (file == "") 
{
	MessageBox.Show("不能为空");
	return;
}
DialogResult result = MessageBox.Show("确定还原吗？", "还原", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
if (result == DialogResult.Yes) 
{
	try 
	{
		using (MySqlCommand cmd = new MySqlCommand()) 
		{
			using (MySqlBackup mb = new MySqlBackup(cmd)) 
			{
				cmd.Connection = mysql.conn;
				mysql. conn.Open();
				mb.ImportFromFile(file);
				mysql. conn.Close();
				MessageBox.Show("已还原");
			}
		}
	}
	catch (Exception ex) 
	{
		MessageBox.Show(ex.Message);
	}
} else 
{
	return;
}
