C# 站点地图图像元素

我有一个在c#中构建xml站点地图的类，我在mvc控制器中使用它来生成站点地图：

public class Location
    {
        public enum eChangeFrequency
        {
            always,
            hourly,
            daily,
            weekly,
            monthly,
            yearly,
            never
        }

        [XmlElement("loc")]
        public string Url { get; set; }

        [XmlElement("changefreq")]
        public eChangeFrequency? ChangeFrequency { get; set; }
        public bool ShouldSerializeChangeFrequency() { return ChangeFrequency.HasValue; }

        [XmlElement("lastmod")]
        public DateTime? LastModified { get; set; }
        public bool ShouldSerializeLastModified() { return LastModified.HasValue; }

        [XmlElement("priority")]
        public double? Priority { get; set; }
        public bool ShouldSerializePriority() { return Priority.HasValue; }

        [XmlElement("image")]
        public Image Image { get; set; }
    }

    [XmlType("image")]
    public class Image
    {
        [XmlElement(ElementName = "loc")]
        public string UrlLocation { get; set; }

        [XmlElement(ElementName = "caption")]
        public string Caption { get; set; }

        [XmlElement(ElementName = "title")]
        public string Title { get; set; }

    }

这是我使用时的输出：

<url>
  <loc>http://...</loc>
  <priority>0.5</priority>
    <image>
      <loc>http://...</loc>
    </image>
</url>

http://...
0.5
http://...

但我想要正确的格式，比如：

<url>
  <loc>http://...</loc>
  <priority>0.5</priority>
  <image:image>
    <image:loc>http://...</image:loc>
  </image:image>
</url>

[XmlType("image")]
    public class Image
    {
        [XmlElement(ElementName = "loc")]
        public string UrlLocation { get; set; }

        [XmlElement(ElementName = "caption")]
        public string Caption { get; set; }

        [XmlElement(ElementName = "title")]
        public string Title { get; set; }

        [XmlNamespaceDeclarations]
        public XmlSerializerNamespaces NameSpace
        {
            get
            {
                XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
                ns.Add("image", "http://www.google.com/schemas/sitemap-image/1.1");
                return ns;
            }
            set { NameSpace = value; }
        }

    }

我想将此前缀添加到图像元素， 感谢您的帮助

阅读本页
有很好的例子。
您应该在映像类中添加XmlSerializerNamespaces类型属性，并且应该添加字符串前缀和字符串命名空间值

我读了这个

用法必须如下所示

Image mySelect = new Image();
        mySelect.Caption = "Caption";
        mySelect.Title = "Title";
        mySelect.UrlLocation = "www";

        XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
        ns.Add("image", "http://flibble");
        XmlSerializer ser = new XmlSerializer(typeof(Image));

        ser.Serialize(Console.Out, mySelect,ns);

我这样加上：

<url>
  <loc>http://...</loc>
  <priority>0.5</priority>
  <image:image>
    <image:loc>http://...</image:loc>
  </image:image>
</url>

[XmlType("image")]
    public class Image
    {
        [XmlElement(ElementName = "loc")]
        public string UrlLocation { get; set; }

        [XmlElement(ElementName = "caption")]
        public string Caption { get; set; }

        [XmlElement(ElementName = "title")]
        public string Title { get; set; }

        [XmlNamespaceDeclarations]
        public XmlSerializerNamespaces NameSpace
        {
            get
            {
                XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
                ns.Add("image", "http://www.google.com/schemas/sitemap-image/1.1");
                return ns;
            }
            set { NameSpace = value; }
        }

    }

这就是输出：

<url>
  <loc>http://...</loc>
  <priority>0.5</priority>
    <image xmlns:image="http://www.google.com/schemas/sitemap-image/1.1">
      <loc>http://...</loc>
    </image>
</url>

http://...
0.5

非常感谢，您能为此类编写此属性的正确格式吗？
