在C＃MVC命名空間或結腸反序列化XML節點

Question

我有下面的XML作爲例子：

<?xml version="1.0" encoding="utf-8"?> 
<feed xmlns="http://www.w3.org/2005/Atom" xmlns:api="http://www.sample.com/api"> 
    <entry> 
    <existing>true</existing> 
    <api:object category="user" id="100"> 
     <api:last-name>Smith</api:last-name> 
     <api:first-name>John</api:first-name> 
    </api:object> 
    </entry> 

    <entry> 
    <existing>false</existing> 
    <api:object category="user" id="101"> 
     <api:last-name>Smith</api:last-name> 
     <api:first-name>Bob</api:first-name> 
    </api:object> 
    </entry> 
</feed> 

現在我嘗試反序列化的XML，並能順利拿到價值爲節點< 現有的>。問題是我得到的節點內的數據的空值爲< api：>前綴。我讀過這與名稱空間有關，但我無法使它工作我正在使用C＃MVC。

我的模型如下：

ElementsUsersRoot.cs

 [Serializable] 
     [XmlType(Namespace = "http://www.w3.org/2005/Atom")] 
     [XmlRoot(ElementName = "feed", Namespace = "http://www.w3.org/2005/Atom", IsNullable = false)] 

     public class ElementsUsersRoot 
     { 
      public ElementsUsersRoot() 
      { 
       ElementsUsersDetails = new List<ElementsUsersData>(); 
      } 

      [XmlElement("entry")] 

      public List<ElementsUsersData> ElementsUsersDetails { get; set; } 

ElementsUsersData.cs

[Serializable] 
    [XmlRoot("entry")] 
    public class ElementsUsersData 
    { 


     [XmlElement("existing")] 
     public bool IsExisting { get; set; } 

     [XmlElement("api:object")] 
     public ElementsUsersAttributes UserAttributes { get; set; }  

    } 

ElementsUsersAttributes.cs

0下面

[Serializable] 
    [XmlRoot("api:object", Namespace = "http://www.sample.com/api")] 
    public class ElementsUsersAttributes 
{ 

     [XmlElement("api:first-name")] 
     public string Fname { get; set; } 

     [XmlElement("api:last-name")] 
     public string Lname{ get; set; } 
} 

代碼：

using (var client = new HttpClient()) 
       { 
        var byteArray = Encoding.ASCII.GetBytes(apiAccount + ":" + apiPassword); 
        var header = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray)); 
        client.DefaultRequestHeaders.Authorization = header; 

        var stream = await client.GetStreamAsync(apiEndpoint); 
        var serializer = new XmlSerializer(typeof(ElementsUsersRoot)); 

        ElementsUsersRoot userXmlData = (ElementsUsersRoot)serializer.Deserialize(stream); 
        //Add cache here 
        return userXmlData; 

       }

正如評論所說，api是一個命名空間前綴，它無關的元素的限定名。

我也會注意到[Serializable]屬性與XmlSerializer無關，所以可以去掉，而且這個[XmlRoot]屬性只和根元素有關。

考慮上述所有考慮的，這些類將工作：

[XmlRoot(ElementName = "feed", Namespace = "http://www.w3.org/2005/Atom")] 
public class ElementsUsersRoot 
{ 
    [XmlElement("entry")] 
    public List<ElementsUsersData> ElementsUsersDetails { get; set; } 
} 

public class ElementsUsersData 
{ 
    [XmlElement("existing")] 
    public bool IsExisting { get; set; } 

    [XmlElement("object", Namespace = "http://www.sample.com/api")] 
    public ElementsUsersAttributes UserAttributes { get; set; } 
} 

public class ElementsUsersAttributes 
{ 
    [XmlElement("first-name")] 
    public string Fname { get; set; } 

    [XmlElement("last-name")] 
    public string Lname { get; set; } 
}
