[英]Sitemap image element
我在C#中有一個用於構建xml網站地圖的類,我在mvc控制器中使用它來生成網站地圖:
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; }
}
這是輸出,當我使用它時:
<url>
<loc>http://...</loc>
<priority>0.5</priority>
<image>
<loc>http://...</loc>
</image>
</url>
但是我想要正確的格式,像這樣:
<url>
<loc>http://...</loc>
<priority>0.5</priority>
<image:image>
<image:loc>http://...</image:loc>
</image:image>
</url>
我想將此前綴添加到圖像元素,謝謝您的幫助
閱讀此頁面https://msdn.microsoft.com/tr-tr/library/system.xml.serialization.xmlnamespacedeclarationsattribute(v=vs.110).aspx
有一個很好的例子。
您應該在Image類中添加XmlSerializerNamespaces type屬性,並且應該添加字符串前綴和字符串名稱空間值。
我閱讀了此XML序列化和名稱空間前綴 。
[XmlType("image", Namespace = "http://flibble")]
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; }
}
用法必須如下。
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);
我這樣添加它:
[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; }
}
}
這是輸出:
<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>
