我想从所有者元素中获取用户名属性。这是序列化代码。

  [XmlTypeAttribute(AnonymousType = true)]
    [XmlRootAttribute(Namespace = "", IsNullable = false, ElementName = "rsp")]
    public partial class VimeoSearchResponse
    {
        private SearchResponseVideosWrapper _videos;
        private string _generated_in;
        private string _stat;

        [XmlElementAttribute("videos", Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
        public SearchResponseVideosWrapper videos
        {
            get { return _videos; }
            set { _videos = value; }
        }
        [XmlAttributeAttribute()]
        public string generated_in
        {
            get { return _generated_in; }
            set { _generated_in = value; }
        }
        [XmlAttributeAttribute()]
        public string stat
        {
            get { return _stat; }
            set { _stat = value; }
        }
    }

    [SerializableAttribute]
    [XmlTypeAttribute(AnonymousType = true)]
    public partial class SearchResponseVideosWrapper
    {
        private SearchResponseVideosWrapperVideo[] _video;
        private string _on_this_page;
        private string _page;
        private string _perpage;
        private string _total;

        [XmlElementAttribute("video", Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
        public SearchResponseVideosWrapperVideo[] video
        {
            get { return _video; }
            set { _video = value; }
        }


        [XmlAttributeAttribute()]
        public string on_this_page
        {
            get { return _on_this_page; }
            set { _on_this_page = value; }
        }
        [XmlAttributeAttribute()]
        public string page
        {
            get { return _page; }
            set { _page = value; }
        }
        [XmlAttributeAttribute()]
        public string perpage
        {
            get { return _perpage; }
            set { _perpage = value; }
        }
        [XmlAttributeAttribute()]
        public string total
        {
            get { return _total; }
            set { _total = value; }
        }
    }

    [SerializableAttribute]
    [XmlTypeAttribute(AnonymousType = true)]
    public partial class SearchResponseVideosWrapperVideo
    {
        private string _title;
        private string _id;
        private string _username;

        [XmlElement()]
        public string title
        {
            get { return _title; }
            set { _title = value; }
        }

        [XmlAttributeAttribute()]
        public string id
        {
            get { return _id; }
            set { _id = value; }
        }

        [XmlElementAttribute("owner")]
        public string username 
        {
            get { return _username; }
            set { _username = value; }
        }        
}

我认为问题就在这里

      [XmlElementAttribute("owner")]
        public string username 
        {
            get { return _username; }
            set { _username = value; }
        }

- <owner display_name="Ertan D." id="1387509" is_plus="0" is_pro="0" is_staff="0" profileurl="http://vimeo.com/user1387509" realname="Ertan D." username="user1387509" videosurl="http://vimeo.com/user1387509/videos">

我怎样才能从所有者那里获得属性..

这是异常详细信息

我收到一个异常，即 XML 文档中存在错误 (1, 1005)。

{“非预期的节点类型元素。ReadElementString 方法只能对内容简单或为空的元素调用。第 1 行，位置 1005。”}

System.InvalidOperationException 被捕获

你需要一个“所有者”类。您还可以考虑在“所有者”类中添加带有集合的“肖像”类。

public class owner
{
    [XmlAttributeAttribute]
    public string username { get; set; }
}



[SerializableAttribute] 
[XmlTypeAttribute(AnonymousType = true)] 
public partial class SearchResponseVideosWrapperVideo 
{ 
    private string _title; 
    private string _id; 
    private string _username; 

    [XmlElement()] 
    public string title 
    { 
        get { return _title; } 
        set { _title = value; } 
    } 

    [XmlAttributeAttribute()] 
    public string id 
    { 
        get { return _id; } 
        set { _id = value; } 
    } 

    [XmlElementAttribute("owner")] 
    public owner owner { get; set; }

}

您正在使用“所有者”的 XmlElementAttribute 注释用户名。这意味着所有者元素应反序列化为字符串属性用户名。

如果要获取用户名，首先必须将所有者反序列化为某个对象。

例如，您可以使用与创建 VimeoSearchResponse 相同的方式添加 Owner 类。

public class Owner
{
    private string _owner;

    [XmlAttribute]
    public string username 
    {
       get { return _owner; } 
       set { _owner = value; }
    }
}
