我通过OAuth从Twitter导入XML。
我正在对http://twitter.com/account/verify_credentials.xml做一个请求,它返回以下XML:
<?xml version="1.0" encoding="UTF-8"?>

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);
}
我的User
类有以下内容:
[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; }
}
但是当它反序列化上面的XML时,应用程序抛出如下:
$exception {"有一个错误在XML文档(2,2)."}系统。异常{系统。InvalidOperationException}
InnerException {"<user xmlns= " >是没有预料到的。”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?
