反序列化动态XML [英] Deserializing Dynamic XML

问题描述

在第一种情况下，一切都非常简单，我有以下XML，我可以反序列化到一个强类型。

In the first scenario, everything is pretty easy, I have the following XML, that I can deserialize to a strong type.

<providers>
   <dprovider>
      <dimensions>
         <width></width>
     </dimensions>
   </dbrovider>

在第二个方案中，并这就是我需要帮助...我有东西多一点活力。

In the 2nd scenario, and this is where I need help... I have something a little more dynamic

<providers>
   <dprovider>
      <dimensions>
         <width></width>
     </dimensions>
   </dbrovider>
     <dprovider>
      <dimensions>
         <height></height>
     </dimensions>
   </dbrovider>

正如你所看到的尺寸子结构是两个项目不同，所以我需要找到一个方法来创建强类型的类，因此它可以处理任何改变尺寸的元素，它可以包含例如一个整体嵌套子结构，每个dbprovider不同。

As you can see the dimensions sub structure is different in both items, so I need to find a way to create the strongly typed class, so that it can handle any change to the dimensions element, it could for example contain a whole nested sub structure, different for each dbprovider.

这是如何做到这一点？

推荐答案

试试这个任何想法

[Serializable]
class Dimension { ... }

[Serializable]
class Height : Dimension { ... }

[Serializable]
class Width : Dimension { ... }

然后，在你的（注意是复数）元素反序列化到类，有此属性：

Then, in the class that your (note the plural) element deserializes into, have this property:

[XmlElement( Type = typeof( Height ), ElementName = "height" )]
[XmlElement( Type = typeof( Width ), ElementName = "width" )]
public Dimension[] DimensionArray {
    get { ... }
    set { ... }
}

下面的的的XML序列化文档（XmlElement的类），所以你可以计算出的其余的细节。

Here's the starting point of documentation on XML serialization (XmlElement class), so you can figure out the rest of the details.

您应该能够序列化/通过简单地从的System.Xml.Serialization 的命名空间。

You should be able to serialize/deserialize your providers object by simply decorating the right properties and classes with the right attributes from the System.Xml.Serialization namespace.
