Question

我使用c＃作为编程语言和MySQL作为DBMS构建了一个Windows窗体应用程序，我想在用户单击时添加一个导出数据库的按钮。到目前为止我创建的是：

MySqlCommand cmd = new MySqlCommand("SELECT * FROM client INTO OUTFILE '"+path+"' FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY'\\n' ", con);
MySqlDataReader dataReader = cmd.ExecuteReader();
dataReader.Read();

但问题是这段代码只导出数据而不是表格的模式。是否有任何方法可以通过 SQL语句导出带有模式的数据库。

您可以使用 MySqlBackup.NET

https://github.com/MySqlBackupNET/MySqlBackup.Net

样例代码：

备份MySQL数据库

using MySql.Data.MySqlClient;

然后输入代码

private void Backup()
{
    string constring = "server=localhost;user=root;pwd=qwerty;database=test;";
    string file = "C:\\backup.sql";
    using (MySqlConnection conn = new MySqlConnection(constring))
    {
        using (MySqlCommand cmd = new MySqlCommand())
        {
            using (MySqlBackup mb = new MySqlBackup(cmd))
            {
                cmd.Connection = conn;
                conn.Open();
                mb.ExportToFile(file);
                conn.Close();
            }
        }
    }
}

还原MySQL数据库

private void Restore()
{
    string constring = "server=localhost;user=root;pwd=qwerty;database=test;";
    string file = "C:\\backup.sql";
    using (MySqlConnection conn = new MySqlConnection(constring))
    {
        using (MySqlCommand cmd = new MySqlCommand())
        {
            using (MySqlBackup mb = new MySqlBackup(cmd))
            {
                cmd.Connection = conn;
                conn.Open();
                mb.ImportFromFile(file);
                conn.Close();
            }
        }
    }
}
