# mysql数据库备份还原

叫我少年

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;
}
