XML反序列化在C＃中的复杂元素

问题描述

我有一些麻烦与我的XML字符串的反序列化到我的对象。我没有得到任何错误，但值不填充（价值不空他们只是，）。我看着那个有同样的问题的一些问题，但这些问题通常包括人不具有 [XmlRoot] 或 [的XmlElement] 定义。

下面是一个有点我的XML字符串：

 字符串的xmlString = @<结果>< dpv_answer值=Y/><拉链值=95118-4007/>< /结果> 
  

下面是deseralize功能：

  StandardAddress地址=新StandardAddress（）;使用
 
（XmlReader中读取= XmlReader.Create（新StringReader（XML）））
 {
试
 {
地址=（StandardAddress）新的XmlSerializer （typeof运算（StandardAddress））反序列化（阅读器）。 
} 
赶上（InvalidOperationException异常X）
 {
 //字符串传递不是XML，简单地返回defaultXmlClass 
} 
} 
 
返回地址; 
  

下面是一个有点对象声明：

  [XmlRoot（结果）] 
公共类StandardAddress 
 {
 [的XmlElement（的ElementName =dpv_answer）] 
公共字符串dpv_answer {搞定;组; } 
 [的XmlElement（的ElementName =拉链）] 
公共字符串拉链{搞定;组; } 
} 
  

解决方案

dpv_answer 和拉链是复杂的元素不只是一个字符串。请尝试以下操作：

  [XmlRoot（结果）] 
公共类StandardAddress 
 {
 [的XmlElement（的ElementName =dpv_answer）] 
公共dpv_answer dpv_answer {搞定;组; } 
 
 [的XmlElement（的ElementName =拉链）] 
公共拉链拉链{搞定;组; } 
} 
 
公共类dpv_answer 
 {
 [XmlAttribute（值）] 
公共字符串值{获得;组; } 
} 
 
 
公共类拉链
 {
 [XmlAttribute（值）] 
公共字符串值{获得;组; } 
} 
  

I am having some troubles with the deserialization of my xml string to my object. I am not getting any errors but the values aren't populating (the values aren't null they are just ""). I've looked at a few questions that had the same issue but those problems usually consisted of people not having the [XmlRoot] or [XmlElement] defined.

Here is a bit of my xml string:

string xmlString = @"<results><dpv_answer value=""Y"" /><zip value=""95118-4007"" /></results>"

Here is the function to deseralize:

StandardAddress address = new StandardAddress();

using (XmlReader reader = XmlReader.Create(new StringReader(xml)))
{
    try
    {
        address = (StandardAddress)new XmlSerializer(typeof(StandardAddress)).Deserialize(reader);
    }
    catch (InvalidOperationException x)
    {
        // String passed is not XML, simply return defaultXmlClass
    }
}

return address;

Here is a bit of the object declaration:

[XmlRoot("results")]
public class StandardAddress
{
    [XmlElement(ElementName = "dpv_answer")]
    public string dpv_answer { get; set; }
    [XmlElement(ElementName = "zip")]
    public string zip { get; set; }
}

解决方案

dpv_answer and zip are complex elements not just a string. Try the following:

[XmlRoot("results")]
public class StandardAddress
{
    [XmlElement(ElementName = "dpv_answer")]
    public dpv_answer dpv_answer { get; set; }

    [XmlElement(ElementName = "zip")]
    public zip zip { get; set; }
}

public class dpv_answer
{
    [XmlAttribute("value")]
    public string Value { get; set; }
}


public class zip
{
    [XmlAttribute("value")]
    public string Value { get; set; }
}
