我如何给一个数组的属性在C＃中序列化过程中？ [英] How do I give an array an attribute during serialization in C#?

问题描述

我试图生成一个用于创建XML这样的片段C＃

I'm trying to generate C# that creates a fragment of XML like this.

<device_list type="list">
    <item type="MAC">11:22:33:44:55:66:77:88</item>
    <item type="MAC">11:22:33:44:55:66:77:89</item>
    <item type="MAC">11:22:33:44:55:66:77:8A</item>
</device_list>

我在考虑使用像这样的：

I was thinking of using something like this:

[XmlArray( "device_list" ), XmlArrayItem("item")]
public ListItem[] device_list { get; set; }

作为属性，与此类声明：

as the property, with this class declaration:

public class ListItem {
    [XmlAttribute]
    public string type { get; set; }

    [XmlText]
    public string Value { get; set; }
}

这给了我内在的序列化，但我不知道该怎么适用 TYPE =列表属性添加到 device_list 上方。

我在考虑（但不知道怎么写的语法），我需要做一个：

I'm thinking (but not sure of how to write the syntax) that I need to do a:

public class DeviceList {
    [XmlAttribute]
    public string type { get; set; }

    [XmlArray]
    public ListItem[] .... This is where I get lost
}

更新基于Dave的回答

Updated based on Dave's responses

public class DeviceList : List<ListItem> {
    [XmlAttribute]
    public string type { get; set; }
}

public class ListItem {
    [XmlAttribute]
    public string type { get; set; }

    [XmlText]
    public string Value { get; set; }
}

和用法目前：

[XmlArray( "device_list" ), XmlArrayItem("item")]
public DeviceList device_list { get; set; }

和类型，而在这样的代码因此被宣称：

And the type, while being declared in the code like thus:

device_list = new DeviceList{type = "list"}
device_list.Add( new ListItem { type = "MAC", Value = "1234566" } );
device_list.Add( new ListItem { type = "MAC", Value = "1234566" } );

没有显示在序列化的类型。这是序列化的结果是：

Isn't showing the type on serialization. This is the result of the serialization:

<device_list>
  <item type="MAC">1234566</item>
  <item type="MAC">1234566</item>
</device_list>

因此很明显，我还是失去了一些东西...

So apparently I'm still missing something...

推荐答案

使用Dave的答案的一部分上面，我发现，这是最好的使用属性在这样的声明类：（注意缺少的属性）

Using part of Dave's answer above, I found that it was best to use the property in the declaring class like this: (note the lack of attributes)

public DeviceList device_list { get; set; }

，然后更新DEVICELIST类是这样的：

and then update the DeviceList class like this:

[XmlType("device_list")]
[Serializable]
public class DeviceList {
    [XmlAttribute]
    public string type { get; set; }

    [XmlElement( "item" )]
    public ListItem[] items { get; set; }
}

和保持原有的ListItem类

and keep the original ListItem class

public class ListItem {
    [XmlAttribute]
    public string type { get; set; }

    [XmlText]
    public string Value { get; set; }
}

和我的序列化是预料之中的：

and my serialization is as expected:

<device_list type="list">
  <item type="MAC">1234567</item>
  <item type="MAC">123456890</item>
</device_list>
