c#中的XML序列化.Net，序列化所有类属性

本文关键字：序列化 属性 Net 中的 XML | 更新日期: 2023-09-27 18:07:30

我要序列化这个类:

[Serializable]
[XmlRoot(ElementName = "Rates")]
public class CbrRate : IRate
{
    public CbrRate()
    {
    }
    public CbrRate(DateTime date, ICurrency currency, decimal rate)
    {
        Currency = currency;
        Date = date;
        Rate = rate;
    }
    [XmlIgnore]
    public string SrcName
    {
        get { return "CBR"; }
    }
    [XmlElement(ElementName = "RequestDate")]
    public DateTime Date { get; set; }
    [XmlIgnore]
    public ICurrency Currency { get; set; }
    [XmlElement(ElementName = "Direction")]
    public string Direction
    {
        get { return "RUR=>" + CodeChar.Trim(); }
    }
    [XmlElement(ElementName = "RateValue")]
    public decimal Rate { get; set; }
    [XmlElement(ElementName = "RateBase")]
    public decimal BaseRate
    {
        get { return Math.Round(Rate/Nominal, 4); }
    }
    [XmlElement(ElementName = "RateCross")]
    public decimal CrossRate
    {
        get { return Math.Round(1.00M/BaseRate, 4); }
    }
    [XmlElement(ElementName = "CodeNum")]
    public int CodeNum
    {
        get { return Currency.CodeNumIso; }
    }
    [XmlElement(ElementName = "CodeISO")]
    public string CodeChar
    {
        get { return Currency.CodeCharIso; }
    }
    [XmlElement(ElementName = "CurrencyName")]
    public string Name
    {
        get { return Currency.Name; }
    }
    [XmlElement(ElementName = "Nominal")]
    public decimal Nominal
    {
        get { return Currency.Nominal; }
    }
}

public static XDocument Serialize<T>(this T source)
{
    var target = new XDocument();
    var s = new XmlSerializer(typeof (T));
    using (var writer = target.CreateWriter())
    {
        s.Serialize(writer, source);
        writer.Close();
    }
    return target;
}

但是，我有:

<?xml version="1.0" encoding="utf-16"?>
<ArrayOfCbrRate xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <CbrRate>
    <RequestDate>2011-09-05T18:49:55.1195696+04:00</RequestDate>
    <RateValue>31.0539</RateValue>
  </CbrRate>
...

如何创建正确的xml，像这样:

<ArrayOfRates>    
<Rates>
       <RequestDate></RequestDate>
       <Direction></Direction>
       <RateValue></RateValue>
       <RateBase></RateBase>
    ...

c#中的XML序列化.Net，序列化所有类属性

首先，. net XmlSerializer将只序列化读/写属性(或字段)。这就是为什么只有RequestDate和RateValue被序列化。

为了实现您提到的XML结构，您需要创建一个包装器类，如Roel所说。

因此，假设您正在序列化List<CbrRate >，您将需要为列表创建一个包装器类，以便按照您的需要对其进行序列化。像这样:

[XmlRoot("root")]
public class ListOfRates 
{
    [XmlArray("ArrayOfRates")]
    [XmlArrayItem("Rate")]
    public List<CbrRate> Rates { get; set; }
}

将生成您想要的XML。或者你可以稍微改变一下属性但是如果你不想有根目录:

[XmlRoot("ArrayOfRates")]
public class ListOfRates 
{
    [XmlArrayItem("Rate")]
    public List<CbrRate> Rates { get; set; }
}

两个属性XmlArray和XmlArrayItem是这里的关键。如果您没有为xml元素提供名称，它将默认为属性名称。
