            XmlNodeList nodes = doc.GetElementsByTagName("order" + Convert.ToString(i+1));
            Console.WriteLine(nodes[i]["Name"].InnerText);
            Console.WriteLine(nodes[i]["ID"].InnerText);
            Console.WriteLine(nodes[i]["Price"].InnerText);
        }
    }
}

我在打开 XML 文件时出错。异常描述为：

Message=Знак "0"， шестнадцатеричное значение 0x30， не может стоять

в начале имени.， строка 3， позиция 10.

问题可能出在节点的名称上吗？XML 文件已成功创建，但无法打开并显示在屏幕上。

应用程序似乎在此语句上失败：

doc.Load("orders.xml");

我做错了什么？你能帮我解决它吗？
