{“ 没想到}反序列化Twitter XML

(adsbygoogle = window.adsbygoogle || []).push({}); 如何解决{“ 没想到}反序列化Twitter XML？

可以使用XmlRoot属性装饰您的根实体，该属性将在编译时使用。

[XmlRoot(Namespace = 'www.contoso.com', ElementName = 'MyGroupName', DataType = 'string', IsNullable=true)]

或在运行时取消序列化时指定root属性。

XmlRootAttribute xRoot = new XmlRootAttribute();xRoot.ElementName = 'user';// xRoot.Namespace = 'http://www.cpandl.com';xRoot.IsNullable = true;XmlSerializer xs = new XmlSerializer(typeof(User),xRoot);解决方法

我正在通过OAuth从Twitter提取XML。

我正在向http://twitter.com/account/verify_credentials.xml发送请求，该请求返回以下XML：

<?xml version='1.0' encoding='UTF-8'?><user> <id>16434938</id> <name>Lloyd Sparkes</name> <screen_name>lloydsparkes</screen_name> <location>Hockley,Essex,UK</location> <description>Student</description> <profile_image_url>http://a3.twimg.com/profile_images/351849613/twitterProfilePhoto_normal.jpg</profile_image_url> <url>http://www.lloydsparkes.co.uk</url> <protected>false</protected> <followers_count>115</followers_count> <profile_background_color>9fdaf4</profile_background_color> <profile_text_color>000000</profile_text_color> <profile_link_color>220f7b</profile_link_color> <profile_sidebar_fill_color>FFF7CC</profile_sidebar_fill_color> <profile_sidebar_border_color>F2E195</profile_sidebar_border_color> <friends_count>87</friends_count> <created_at>Wed Sep 24 14:26:09 +0000 2008</created_at> <favourites_count>0</favourites_count> <utc_offset>0</utc_offset> <time_zone>London</time_zone> <profile_background_image_url>http://s.twimg.com/a/1255366924/images/themes/theme12/bg.gif</profile_background_image_url> <profile_background_tile>false</profile_background_tile> <statuses_count>1965</statuses_count> <notifications>false</notifications> <geo_enabled>false</geo_enabled> <verified>false</verified> <following>false</following> <status> <created_at>Mon Oct 12 19:23:47 +0000 2009</created_at> <id>4815268670</id> <text>&#187; @alexmuller your kidding? it should all be &quot;black tie&quot; dress code</text> <source>&lt;a href=&quot;http://code.google.com/p/wittytwitter/&quot; rel=&quot;nofollow&quot;&gt;Witty&lt;/a&gt;</source> <truncated>false</truncated> <in_reply_to_status_id>4815131457</in_reply_to_status_id> <in_reply_to_user_id>8645442</in_reply_to_user_id> <favorited>false</favorited> <in_reply_to_screen_name>alexmuller</in_reply_to_screen_name> <geo/> </status></user>

我正在使用以下代码反序列化：

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); }

我的User课程有以下内容：

[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，当反序列化以上XML时，应用程序将引发以下情况：

$ exception {“ XML文档（2，2）中存在错误。”} System.Exception {System.InvalidOperationException}

InnerException {“ <用户xmlns =”>不是预期的。“} System.Exception {System.InvalidOperationException}

现在，我进行了搜索，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，但是我没有序列化它，所以我不能。

我也有一些用于接收状态的代码，效果很好。

那么有人可以向我解释为什么会发生错误吗？以及可能的解决方案？

提前致谢。
