{"<user xmlns= " >不是预期的。反序列化Twitter XML

我通过OAuth从Twitter导入XML。

我正在做一个请求http://twitter.com/account/verify_credentials.xml，它返回以下XML:

<?xml version="1.0" encoding="UTF-8"?>

  </status>
</user>

我使用下面的代码来反序列化:

    public User VerifyCredentials()
    {
        string url = "http://twitter.com/account/verify_credentials.xml";
        string xml = _oauth.oAuthWebRequestAsString(oAuthTwitter.Method.GET, url, null);

        XmlSerializer xs = new XmlSerializer(typeof(User),"");

        MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(xml));

        return (User)xs.Deserialize(ms);
    }

我有以下为我的用户类:

 [System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public partial class User
{

    [XmlElement(ElementName = "id")]       
    public long Id { get; set; }

    [XmlElement(ElementName = "name")] 
    public string Name { get; set; }

    [XmlElement(ElementName = "screen_name")]       
    public string ScreenName { get; set; }

    [XmlElement(ElementName = "location")]       
    public string Location { get; set; }

    [XmlElement(ElementName = "description")]      
    public string Description { get; set; }

    [XmlElement(ElementName = "profile_image_url")]      
    public string ProfileImageUrl { get; set; }

    [XmlElement(ElementName = "url")]       
    public string Url { get; set; }

    [XmlElement(ElementName = "protected")]      
    public bool Protected { get; set; }

    [XmlElement(ElementName = "followers_count")]      
    public int FollowerCount { get; set; }

    [XmlElement(ElementName = "profile_background_color")]       
    public string ProfileBackgroundColor { get; set; }

    [XmlElement(ElementName = "profile_text_color")]       
    public string ProfileTextColor { get; set; }

    [XmlElement(ElementName = "profile_link_color")]       
    public string ProfileLinkColor { get; set; }

    [XmlElement(ElementName = "profile_sidebar_fill_color")]       
    public string ProfileSidebarFillColor { get; set; }

    [XmlElement(ElementName = "profile_sidebar_border_color")]      
    public string ProfileSidebarBorderColor { get; set; }

    [XmlElement(ElementName = "friends_count")]     
    public int FriendsCount { get; set; }

    [XmlElement(ElementName = "created_at")]     
    public string CreatedAt { get; set; }

    [XmlElement(ElementName = "favourties_count")]      
    public int FavouritesCount { get; set; }

    [XmlElement(ElementName = "utc_offset")]      
    public int UtcOffset { get; set; }

    [XmlElement(ElementName = "time_zone")]       
    public string Timezone { get; set; }

    [XmlElement(ElementName = "profile_background_image_url")]        
    public string ProfileBackgroundImageUrl { get; set; }

    [XmlElement(ElementName = "profile_background_tile")]        
    public bool ProfileBackgroundTile { get; set; }

    [XmlElement(ElementName = "statuese_count")]        
    public int StatusesCount { get; set; }

    [XmlElement(ElementName = "notifications")]       
    public string Notifications { get; set; }

    [XmlElement(ElementName = "geo_enabled")]       
    public bool GeoEnabled { get; set; }

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

    [XmlElement(ElementName = "following")]
    public string Following { get; set; }

    [XmlElement(ElementName = "status", IsNullable=true)]
    public Status CurrentStatus { get; set; }

}

但是当它反序列化上面的XML时，应用程序抛出如下:

$exception {" XML文档(2,2)中存在错误。"}系统。异常{系统。InvalidOperationException}

InnerException {"<user xmlns= " >不是预期的。"}系统。异常{系统。InvalidOperationException}

现在我已经四处搜索，我能找到的最佳解决方案是在序列化内容时向序列化器添加空白名称空间，但我没有序列化它，所以我不能。

我还有一些用于接收状态的代码，这些代码工作得很好。

有人能解释一下为什么会出现错误吗?以及一个可能的解决方案?

更简单的方法是在类的顶部添加以下注释:

[Serializable, XmlRoot("user")]
public partial class User
{
}

其他回答

XmlSerializer xs = new XmlSerializer(typeof(User), new XmlRootAttribute("yourRootName"));

对我来说唯一有效的方法就是用大卫瓦伦丁的密码。使用根属性。在Person类中没有帮助。

我有这个简单的Xml:

<?xml version="1.0"?>
<personList>
 <Person>
  <FirstName>AAAA</FirstName>
  <LastName>BBB</LastName>
 </Person>
 <Person>
  <FirstName>CCC</FirstName>
  <LastName>DDD</LastName>
 </Person>
</personList>

c#类:

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

从Main方法反序列化c#代码:

XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "personList";
xRoot.IsNullable = true;
using (StreamReader reader = new StreamReader(xmlFilePath))
{
List<Person> result = (List<Person>)(new XmlSerializer(typeof(List<Person>), xRoot)).Deserialize(reader);
 int numOfPersons = result.Count;
}

错误信息是如此模糊，对于我来说，我有这样的代码:

var streamReader = new StreamReader(response.GetResponseStream());
var xmlSerializer = new XmlSerializer(typeof(aResponse));
theResponse = (bResponse) xmlSerializer.Deserialize(streamReader);

注意xmlSerializer是用aResponse实例化的，但在反序列化时，我意外地将它强制转换为bresonance。

以上这些对我都不起作用，但这是: 检查类的Root元素的名称是否与XML中区分大小写的名称完全相同。

我的问题是我的一个元素有xmlns属性:

<?xml version="1.0" encoding="utf-8"?>
<RETS ReplyCode="0">
    <RETS-RESPONSE xmlns="blahblah">
        ...
    </RETS-RESPONSE>
</RETS>

无论我尝试什么，xmlns属性似乎破坏了序列化器，所以我从xml文件中删除了xmlns="…"的任何痕迹:

<?xml version="1.0" encoding="utf-8"?>
<RETS ReplyCode="0">
    <RETS-RESPONSE>
        ...
    </RETS-RESPONSE>
</RETS>

瞧!一切工作。

我现在解析xml文件，在反序列化之前删除这个属性。不确定为什么这样工作，也许我的情况不同，因为包含xmlns属性的元素不是根元素。
