如何序列化XML到asp.net网页API所需的格式 [英] How to serialize xml into desired format in asp.net web api

问题描述

我正在asp.net的MVC 4个Web API。我有一个类一样，

I am working on asp.net mvc 4 web api. I have a class like,

public class Quiz
{
public int QuizId{get; set;}
public string title{get; set;}
...
...
}

和我现在想找回quizs的列表中，这样写道：我喜欢，

and now i am trying to retrieve list of quizs so i wrote like,

public List<Quiz> GetQuizs()
{
return repository.ListQuizs();
}

我需要XML响应，所以我必须在webapi.config文件进行配置一样，

i need xml response so i have made configuration in webapi.config file like,

config.Formatters.XmlFormatter.UseXmlSerializer = true;

和我得到的回应一样，

<ArrayOfQuiz xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Quiz>
<QuizId>4</QuizId>
<title>Master Minds</title>
</Quiz>
<Quiz>
<QuizId>5</QuizId>
<title>Master Minds</title>
</Quiz>
</ArrayOfQuiz>

但我希望像

<Quizs>
<Quiz>
<QuizId>4</QuizId>
<title>Master Minds</title>
</Quiz>
<Quiz>
<QuizId>5</QuizId>
<title>Master Minds</title>
</Quiz>
</Quiz>

我试图像，

public class quizs:List<Quiz>{}
public class Quiz
{
//properties here
}

但我无法quizs列表加载到quizs类。请指导我。

but i am unable to load list of quizs into quizs class. please guide me.

推荐答案

是否有任何理由为什么你在DataContract serialiszer使用XmlSerializer？

Is there any reason why you are using the XmlSerializer over the DataContract serialiszer?

如果没有你可以达到你想要的东西，像这样：

If not you can achieve what you want like so:

1. 删除config.Formatters.XmlFormatter.UseXmlSerializer = TRUE;从你的配置


2. 添加一个引用到System.Runtime.Serialisation


3. 声明你的类和控制器

code

[DataContract(Namespace = "")]
public class Quiz
{
    [DataMember]
    public int QuizId { get; set; }
    [DataMember(Name = "title")]
    public string Title { get; set; }
}

[CollectionDataContract(Name = "Quizs", Namespace = "")]
public class QuizCollection : List<Quiz>
{
}

public class QuizsController : ApiController
{
    public QuizCollection Get()
    {
        return new QuizCollection
                       {
                           new Quiz {QuizId = 4, Title = "Master Minds"},
                           new Quiz {QuizId = 5, Title = "Another Title"}
                       };
    }
}

最后使用HTML头接受：应用程序/ XML致电您的服务

Finally call your service using the html header "accept : application/xml"

和你的结果应该是这样的：

And your result should be like:

<Quizs xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
    <Quiz>
        <QuizId>4</QuizId>
        <title>Master Minds</title>
        </Quiz>
    <Quiz>
        <QuizId>5</QuizId>
        <title>Another Title</title>
    </Quiz>
</Quizs>

关于你的命名空间NB。他们是如何设置到命名空间=属性中删除它们。你要蒋张关系删除的xmlns：I =htt​​p://www.w3.org/2001/XMLSchema-instance它需要有让XML处理空值。

Regarding your namespaces NB. how they are set to namespace = "" in attributes to remove them. You are going to strugle to remove xmlns:i="http://www.w3.org/2001/XMLSchema-instance" it needs to be there to allow the XML to handle null values.
