如何设置两个连接字符串MySqlCommand对象参数？

MySqlConnection connection1 = new MySqlConnection(connectionString1);
MySqlConnection connection2 = new MySqlConnection(connectionString2);

MySqlCommand command1 = new MySqlCommand(query1, connection1);
MySqlCommand command2 = new MySqlCommand(query2, connection2);

command1.Parameters.AddWithValue("@param1", value1);
command2.Parameters.AddWithValue("@param2", value2);

using (MySqlDataReader reader1 = command1.ExecuteReader())
{
    while (reader1.Read())
    {
        // 处理查询结果
    }
}

int rowsAffected = command2.ExecuteNonQuery();
