c# - 从带有图像的 XSD 站点地图生成 C# 类

Question

有人可以帮我从 XSD(站点地图带有图像)生成 C# 类吗？

   <image:image>
     <image:loc>http://example.com/photo.jpg</image:loc>

这是我用 xsd.exe 工具生成的类:

但我有前缀“image:”的问题，我不知道如何将这个前缀添加到序列化的 xml。如果我通过添加分号修改元素名称，那么它会转义 'image_x003A_image'

Answer 1

我也用过xsd.exe工具，也遇到了同样的问题。我是这样解决的:

在 urlset 类中，添加以下 [XmlNamespaceDeclarations] 属性并创建一个添加“image”xml 命名空间的构造函数:

    [XmlNamespaceDeclarations]
    public XmlSerializerNamespaces xmlns = new XmlSerializerNamespaces();


  public urlset()
    {
        xmlns.Add("image", "http://www.google.com/schemas/sitemap-image/1.1");
    }

在我的例子中，我只需要一个图像，所以我在 tUrl

中的图像属性中添加了以下属性

        [XmlElement(Namespace = "http://www.google.com/schemas/sitemap-image/1.1")]
    public image image
    {
        get
        {
            return this.imageField;
        }
        set
        {
            this.imageField = value;
        }
    }

然后将“图像:”前缀添加到我所有的图像元素。您应该能够为您的图像列表执行类似的操作，以将其与您在上面创建的命名空间相关联。
