[英]How do I XML deserialize an array of arrays in c#?
I am trying to deserialize an object of credit card bins for brand validation on a form, but can't get it done properly. 我正在尝试反序列化信用卡箱的对象以在表单上进行品牌验证,但无法正确完成。 Either the inside object doesn't deserialize, or the main list of brands comes null.
内部对象不反序列化,或者主要品牌列表为空。 Can anyone give me a hand or two?
任何人都可以给我一两手牌吗?
My XML is like this: 我的XML是这样的:
<?xml version="1.0" encoding="utf-8"?>
<Brands>
<Brand type="visa">
<Bins>
<Bin enabled="true" value="123" />
<Bin enabled="true" value="456" />
<Bin enabled="true" value="789" />
</Bins>
</Brand>
<Brand type="master">
<Bins>
<Bin enabled="true" value="987" />
<Bin enabled="true" value="654" />
<Bin enabled="true" value="321" />
</Bins>
</Brand>
</Brands>
and my latest code(which brings brandsCollection null ) is: 而我的最新代码(其中brandsCollection为null )是:
[XmlRoot("Brands")]
public class CreditCardBrand
{
[XmlArray("Brands"), XmlArrayItem("Brand")]
public CreditCardBrandCollection[] brandsCollection { get; set; }
}
public class CreditCardBrandCollection
{
[XmlElement("Bins")]
public CreditCardBrandBins[] binsCollection { get; set; }
[XmlAttribute("type")]
public CreditCardBrands brand { get; set; }
}
public class CreditCardBrandBins
{
[XmlAttribute("value")]
public string bin { get; set; }
[XmlAttribute("enabled")]
public bool enabled { get; set; }
}
I want to deserialize this xml into an array of Brands, each brand having a property name(type) and an array of bins(only the enabled ones) associated to them, so I can put it in memory at my system on startup. 我想将这个xml反序列化为一个Brands数组,每个品牌都有一个属性名称(类型)和一个与它们相关联的bin(只有已启用的)数组,因此我可以在启动时将它放在我的系统的内存中。
It is actually very easy. 这实际上很容易。 You are just confusing — or, better to say, duplicating — the root element declaration and the way you attribute the
brandsCollection
array. 您只是混淆 - 或者更好地说,重复 - 根元素声明以及您对
brandsCollection
数组的归属方式。 You have to change the declaration as follows: 您必须按如下方式更改声明:
[XmlRoot("Brands")]
public class CreditCardBrand
{
[XmlElement("Brand")]
public CreditCardBrandCollection[] brandsCollection { get; set; }
}
Here [XmlElement]
causes each element of the array to be represented by a single <Brand>
tag. 这里
[XmlElement]
导致数组的每个元素由单个<Brand>
标记表示。 In you original code you described an XML which would have to look like this: 在原始代码中,您描述了一个XML,它必须如下所示:
<Brands>
<Brands> <!-- duplicate Brands element here -->
<Brand type="…">…</Brand>
<Brand type="…">…</Brand>
<Brand type="…">…</Brand>
…
</Brands>
</Brands>
If you want to use Linq2Xml 如果你想使用Linq2Xml
XDocument xDoc = XDocument.Parse(xml); //or XDocument.Load(filename)
List<CreditCardBrand> brands =
xDoc.Descendants("Brand")
.Select(br => new CreditCardBrand()
{
Type = br.Attribute("type").Value,
Bins = br.Descendants("Bin")
.Select(b => new CreditCardBin(){
Enabled = (bool)b.Attribute("enabled"),
Value = b.Attribute("value").Value,
}).Where(b => b.Enabled == true)
.ToList()
})
.ToList();
-- -
public class CreditCardBrand
{
public string Type { get; set; }
public List<CreditCardBin> Bins { get; set; }
}
public class CreditCardBin
{
public string Value { get; set; }
public bool Enabled { get; set; }
}
