C# 将对象序列化为XML，仅使用引用ID

我定义了一个包含组件的对象。每个组件都可以包含其他组件作为子组件。大概是这样的：

[Serializable]
public class Thing
{
    private String name;
    private List<MyComponent> components;
    //...
}

[Serializable]
public class MyComponent
{
    private String name;
    private List<MyComponent> subcomponents;
    private String componentID;
    //...
}

<Thing>
  <ID>TH_001<ID>
  <Name>My Test Thing</Name>
  <Components>
     <MyComponent>
        <ComponentID>CMP_001</ComponentID>
            <Name>Foo</Name>
        </MyComponent>        
        <MyComponent>
            <ComponentID>CMP_002</ComponentID>
            <Name>Bar</Name>
            <Subcomponents>
                <MyComponent>
                    <ComponentID>CMP_001</ComponentID>
                     <Name>Foo</Name>
                <MyComponent>
            </Subcomponents>
        </MyComponent>
        <MyComponent>
            <ComponentID>CMP_003</ComponentID>
            <Name>Blergle</Name>
        </MyComponent>   
        <MyComponent>
           <ID>CMP_004</ID>
           <Name>MasterComponent</Name>
          <SubComponents>
                 <MyComponent>
                   <ComponentID>CMP_002</ComponentID>
                   <Name>Bar</Name>
                   <Subcomponents>
                      <MyComponent>
                         <ComponentID>CMP_001</ComponentID>
                         <Name>Foo</Name>
                      <MyComponent>
                    </Subcomponents>
                  </MyComponent>
                  <MyComponent>
                     <ComponentID>CMP_003</ComponentID>
                     <Name>Blergle</Name>
                  </MyComponent>  
         </SubComponents>
      </MyComponent>
   </Components>
 </Thing>

<Thing>
  <ID>TH_001<ID>
  <Name>My Test Thing</Name>
  <Components>
        <MyComponent>
            <ComponentID>CMP_001</ComponentID>
            <Name>Foo</Name>
        </MyComponent>        
        <MyComponent>
            <ComponentID>CMP_002</ComponentID>
            <Name>Bar</Name>
            <Subcomponents>
                <MyComponent ID="CMP_001" />
            </Subcomponents>
        </MyComponent>
        <MyComponent>
            <ComponentID>CMP_003</ComponentID>
            <Name>Blergle</Name>
        </MyComponent>   
        <MyComponent>
           <ID>CMP_004</ID>
           <Name>MasterComponent</Name>
          <SubComponents>
                 <MyComponent ID="CMP_002" />
                 <MyComponent ID="CMP_003" />
          </SubComponents>
      </MyComponent>
   </Components>
 </Thing>

当我将

Thing

类型的对象序列化为XML时，我得到如下结果：

[Serializable]
public class Thing
{
    private String name;
    private List<MyComponent> components;
    //...
}

[Serializable]
public class MyComponent
{
    private String name;
    private List<MyComponent> subcomponents;
    private String componentID;
    //...
}

<Thing>
  <ID>TH_001<ID>
  <Name>My Test Thing</Name>
  <Components>
     <MyComponent>
        <ComponentID>CMP_001</ComponentID>
            <Name>Foo</Name>
        </MyComponent>        
        <MyComponent>
            <ComponentID>CMP_002</ComponentID>
            <Name>Bar</Name>
            <Subcomponents>
                <MyComponent>
                    <ComponentID>CMP_001</ComponentID>
                     <Name>Foo</Name>
                <MyComponent>
            </Subcomponents>
        </MyComponent>
        <MyComponent>
            <ComponentID>CMP_003</ComponentID>
            <Name>Blergle</Name>
        </MyComponent>   
        <MyComponent>
           <ID>CMP_004</ID>
           <Name>MasterComponent</Name>
          <SubComponents>
                 <MyComponent>
                   <ComponentID>CMP_002</ComponentID>
                   <Name>Bar</Name>
                   <Subcomponents>
                      <MyComponent>
                         <ComponentID>CMP_001</ComponentID>
                         <Name>Foo</Name>
                      <MyComponent>
                    </Subcomponents>
                  </MyComponent>
                  <MyComponent>
                     <ComponentID>CMP_003</ComponentID>
                     <Name>Blergle</Name>
                  </MyComponent>  
         </SubComponents>
      </MyComponent>
   </Components>
 </Thing>

<Thing>
  <ID>TH_001<ID>
  <Name>My Test Thing</Name>
  <Components>
        <MyComponent>
            <ComponentID>CMP_001</ComponentID>
            <Name>Foo</Name>
        </MyComponent>        
        <MyComponent>
            <ComponentID>CMP_002</ComponentID>
            <Name>Bar</Name>
            <Subcomponents>
                <MyComponent ID="CMP_001" />
            </Subcomponents>
        </MyComponent>
        <MyComponent>
            <ComponentID>CMP_003</ComponentID>
            <Name>Blergle</Name>
        </MyComponent>   
        <MyComponent>
           <ID>CMP_004</ID>
           <Name>MasterComponent</Name>
          <SubComponents>
                 <MyComponent ID="CMP_002" />
                 <MyComponent ID="CMP_003" />
          </SubComponents>
      </MyComponent>
   </Components>
 </Thing>

在这种情况下，一个组件只完全定义一次，然后由ID引用。我不太确定如何最好地解决这个问题，或者是否有更好的方法。

请查看。它们提供了一系列控制输出的选项。例如，如果要将类属性序列化为属性，只需添加一个XmlAttribute：

[XmlAttribute(AttributeName="id")]
private String componentID;

以后您打算如何使用这个序列化的XML？我不太清楚为什么冗余会成为一个问题…@Baldrick:我正计划将XML转换为HTML，我查看了它的第一个版本，并认为“哦，这会很混乱，为什么我不能通过某种标识符引用现有组件？”。。。我想我应该尝试对第一个XML示例执行转换，但我的直觉反应是“啊！”。过几天我不太累的时候我应该再试一次。
