我正在尝试生成C#,它会像这样创建一个XML片段。
<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>
我在考虑使用这样的东西:
[XmlArray( "device_list" ), XmlArrayItem("item")]
public ListItem[] device_list { get; set; }
作为属性,使用此类声明:
public class ListItem {
[XmlAttribute]
public string type { get; set; }
[XmlText]
public string Value { get; set; }
}
这给了我内部序列化,但我不知道如何将type="list"
属性应用于上面的device_list
。
我正在考虑(但不确定如何编写语法)我需要做的事情:
public class DeviceList {
[XmlAttribute]
public string type { get; set; }
[XmlArray]
public ListItem[] .... This is where I get lost
}
根据Dave的回复进行了更新
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; }
}
目前的用法是:
[XmlArray( "device_list" ), XmlArrayItem("item")]
public DeviceList device_list { get; set; }
类型,同时在代码中声明如此:
device_list = new DeviceList{type = "list"}
device_list.Add( new ListItem { type = "MAC", Value = "1234566" } );
device_list.Add( new ListItem { type = "MAC", Value = "1234566" } );
未在序列化中显示类型。这是序列化的结果:
<device_list>
<item type="MAC">1234566</item>
<item type="MAC">1234566</item>
</device_list>
显然我仍然缺少一些东西......

使用上面Dave的部分回答,我发现最好在声明类中使用这个属性:(注意缺少属性)
public DeviceList device_list { get; set; }
然后像这样更新DeviceList类:
[XmlType("device_list")]
[Serializable]
public class DeviceList {
[XmlAttribute]
public string type { get; set; }
[XmlElement( "item" )]
public ListItem[] items { get; set; }
}
并保留原始的ListItem类
public class ListItem {
[XmlAttribute]
public string type { get; set; }
[XmlText]
public string Value { get; set; }
}
我的序列化符合预期:
<device_list type="list">
<item type="MAC">1234567</item>
<item type="MAC">123456890</item>
</device_list>

不使用ListItem[]
,而是从List<T>
派生一个名为DeviceList的新类:
public class DeviceList : List<ListItem>
{
[XmlElement(ElementName = "type")]
public string ListType {get;set;}
}
然后,在包含类中使用该类来序列化XML。类型值可以作为父节点的元素包含在内,具体取决于您配置序列化的方式。我不记得确切的语法,但我认为类属性默认添加为节点元素。
包含类:
public class SerializeMyStuff
{
public SeriazlieMyStuff()
{
ListOfDevices = new DeviceList();
ListOfDevices.ListType = "list";
}
[XmlArray( "device_list" ), XmlArrayItem("item")]
public DeviceList ListOfDevices {get;set;}
}

您还可以通过在容器类中实现[IXmlSerializable][1]
来实现所需的行为:
使用以下代码,我得到以下标记:
<?xml version="1.0"?>
<DeviceList type="list">
<Item xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" type="MAC">11:22:33:44:55:66:77:88</Item>
<Item xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" type="MAC">11:22:33:44:55:66:77:89</Item>
<Item xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" type="MAC">11:22:33:44:55:66:77:8A</Item>
</DeviceList>
代码:
public class Item
{
[XmlAttribute("type")]
public string Type { get; set; }
[XmlText]
public string Value { get; set; }
}
public class DeviceList : IXmlSerializable
{
public string Type { get; set; }
public List<Item> Items { get; set; }
public System.Xml.Schema.XmlSchema GetSchema()
{
return null;
}
public void ReadXml(System.Xml.XmlReader reader)
{
reader.MoveToContent();
}
public void WriteXml(System.Xml.XmlWriter writer)
{
writer.WriteAttributeString("type", Type);
XmlSerializer serializer = new XmlSerializer(typeof(Item));
foreach (var item in Items)
{
serializer.Serialize(writer, item);
}
}
}
我在main方法中使用以下代码:
var dlist = new DeviceList
{
Type = "list",
Items = new List<Item>
{
new Item {Type = "MAC", Value = "11:22:33:44:55:66:77:88"},
new Item {Type = "MAC", Value = "11:22:33:44:55:66:77:89"},
new Item {Type = "MAC", Value = "11:22:33:44:55:66:77:8A"},
}
};
using(FileStream stream = new FileStream(@"D:\jcoletest.xml", FileMode.Create, FileAccess.Write))
{
new XmlSerializer(typeof (DeviceList)).Serialize(stream, dlist);
}
