我试图让我的 httphandler 打印出一个格式如下的 XML 文件：

<ScheduledShows>
    <ScheduledShowElement>...</ScheduledShowElement>
    <ScheduledShowElement>...</ScheduledShowElement>
    <ScheduledShowElement>...</ScheduledShowElement>
</ScheduledShows>

但由于某种原因，ScheduledShow.cs 中的属性 XmlRoot("ScheduledShowElement") 没有按照我希望的方式工作。相反，我得到的输出是：

<ScheduledShows>
    <ScheduledShow>...<ScheduledShow>
    <ScheduledShow>...<ScheduledShow>
    <ScheduledShow>...<ScheduledShow
</ScheduledShows>

基本上，节点的名称不会被覆盖为 . 如何让我的 xml 序列化程序将节点标记为？

下面是我的代码和 xml 输出。谢谢！

我在这里找到了我的问题的答案：

http://social.msdn.microsoft.com/Forums/en-US/asmxandxml/thread/4b228734-a209-445a-991c-0420b381ac93

我刚用过[XmlType("")]，效果很好。

using System;
using System.Xml.Serialization;


namespace CommunityServer.Scheduler
{

    [XmlType("ScheduledShowElement")]
    public class ScheduledShow
    {

      ...
    }
}

[XmlRoot(...)]只影响最外面的元素 ( <ScheduledShows>...</ScheduledShows>)。我怀疑你想要[XmlElement(...)]. 当然，另一种方法是编写一个对象包装器：

[XmlRoot("SheduledShows")]
public class Shows {
    [XmlElement("SheduledShowElement")]
    public List<Show> Shows {get;set;}
}

并序列化这个包装对象，而不仅仅是一个列表。

您需要使用接受 a 的重载构造函数XmlAttributeOverrides并确保覆盖ScheduledShow类的名称。

我还使用了 XmlType属性[XmlType("")]并工作了。

[XmlRoot]并且[XmlType]仅适用于课程。

[XmlElement]仅用于属性。
