C# 如何从元素属性、XML序列化中获取值

我想从vimeo xml中获取一个属性。。下面是xml文档的结构

<?xml version="1.0" encoding="UTF-8" ?> 
- <rsp generated_in="0.6533" stat="ok">
- <videos on_this_page="15" page="1" perpage="15" total="329">

我想问题就在这里

      [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">

[xmlementAttribute（“所有者”）]
公共字符串用户名
{
获取{return\u username；}
设置{u username=value；}
}
- 

如何从所有者处获取属性

这里是例外细节

我得到一个异常，XML文档中有一个错误（1， 1005).

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

捕获到System.InvalidOperationException

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; }

}

您正在用“所有者”的XmlElementAttribute注释用户名 这意味着应该将owner元素反序列化为字符串属性username

如果您想获取用户名，首先必须将所有者反序列化到某个对象中

例如，您可以按照创建VimeoSearchResponse的相同方式添加所有者类

public class Owner
{
    private string _owner;

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

你有例外吗？是否分配了错误的值？@IAbstract，我编辑了我的问题。。我想，它找不到所有者元素..你有例外吗？是否分配了错误的值？@IAbstract，我编辑了我的问题。。我想，它找不到所有者元素..Thanx，我也这么想，但我不知道如何使它成为SearchResponseVideo SwrapperVideo类的属性？@HarunAbi-没问题。。很高兴能帮上忙。Thanx，我也这么想，但我不知道如何使它成为SearchResponseVideo类的属性？@HarunAbi-没问题。。很乐意帮忙。
