反序列化字符串列表

我試圖將XML反序列化爲C＃對象。我已經嘗試了很多方案，但不能爲我的生活獲取反序列化來獲取choices。請參見下面的代碼...反序列化字符串列表

的XML ...

@"<?xml version=""1.0"" encoding=""UTF-8""?> 
<survey> 
    <question> 
     <type>multiple-choice</type> 
     <text>Question 1</text> 
     <choices> 
      <choice>Answer A</choice> 
      <choice>Answer B</choice> 
      <choice>Answer C</choice> 
     </choices> 
    </question> 
    <question> 
     <type>multiple-choice</type> 
     <text>Question 2</text> 
     <choices> 
      <choice>Answer a</choice> 
      <choice>Answer b</choice> 
     </choices> 
    </question> 
</survey>

我的C＃模型...

[XmlType("question")] 
public struct Question 
{ 
    public String type; 
    public String text; 
    public Choices choices; 
}; 

public class Choices : List<String> { }; 

[XmlType("survey")] 
public class Survey 
{ 
    [XmlElement(ElementName = "question")] 
    public Question[] Questions; 
};

Deserialisation ...

using System.Xml.Serialization; 

Survey survey; 
XmlSerializer serializer = new XmlSerializer(typeof(Survey)); 
survey = (Survey)serializer.Deserialize(reader);

結果顯示爲JSON ...

{"Questions":[ 
{"type":"multiple-choice","text":"Question 1","choices":[]}, 
{"type":"multiple-choice","text":"Question 2","choices":[]} 
]}

我猜應該是'公開名單選擇;'而不是'公共選擇的選擇;'（看我的答案）。另外，「選擇」類不應該是「列表」的孩子。 –

@MarkusSafar，謝謝，是的，我已經嘗試過以及'public String []選擇;'但是它不能讓它工作，這在工作中遇到問題時很奇怪。但是，當我添加托馬斯的回答 – spiderplant0

上choices添加這些屬性：

[XmlArray] 
[XmlArrayItem("choice")] 
public Choices choices;

它不應該是public List<string> choices;而不是public Choices choices;？因爲你做了Question（使用數組）。

我可以太遠超出了這個問題的範圍，但VS2013有一個很酷的功能：Edit-->Paste Special--> Paste XML As Classes

/// <remarks/> 
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)] 
[System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = false)] 
public partial class survey 
{ 

    private surveyQuestion[] questionField; 

    /// <remarks/> 
    [System.Xml.Serialization.XmlElementAttribute("question")] 
    public surveyQuestion[] question 
    { 
    get 
    { 
     return this.questionField; 
    } 
    set 
    { 
     this.questionField = value; 
    } 
    } 
} 

/// <remarks/> 
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)] 
public partial class surveyQuestion 
{ 

    private string typeField; 

    private string textField; 

    private string[] choicesField; 

    /// <remarks/> 
    public string type 
    { 
    get 
    { 
     return this.typeField; 
    } 
    set 
    { 
     this.typeField = value; 
    } 
    } 

    /// <remarks/> 
    public string text 
    { 
    get 
    { 
     return this.textField; 
    } 
    set 
    { 
     this.textField = value; 
    } 
    } 

    /// <remarks/> 
    [System.Xml.Serialization.XmlArrayItemAttribute("choice", IsNullable = false)] 
    public string[] choices 
    { 
    get 
    { 
     return this.choicesField; 
    } 
    set 
    { 
     this.choicesField = value; 
    } 
    } 
}

中描述的屬性時，它會起作用。謝謝你，很高興知道。 – spiderplant0
