XML反序列化<RSS的xmlns =“”>预计不会

Question

这些另外一个....

我已经通过堆栈溢出许多其他的例子看了看，还没有找到一个解决方案，使这项工作。

错误：

There is an error in XML document (1, 41). 
System.Xml 
    at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle, XmlDeserializationEvents events) 
    at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader) 
    at CatalogInterface_1_1.MainWindow.cmdConvertToGoogle_Click(Object sender, RoutedEventArgs e) in C:\Users\Jamie.Marshall\Documents\Visual Studio 2015\Projects\CatalogInterface_1_1\CatalogInterface_1_1\MainWindow.xaml.cs:line 239 
<rss xmlns=''> was not expected. 

对象类：

public class GCatalog 
{ 
    [XmlType(AnonymousType = true)] 
    [XmlRoot(ElementName = "rss", Namespace = "http://base.google.com/ns/1.0")] 
    public partial class googleRss 
    { 
     [XmlAttribute("Version")] 
     public string Version { get; set; } 
     [XmlElement("channel")] 
     public rssChannel Channel { get; set; } 
    } 
    [XmlType(AnonymousType = true)] 
    public partial class rssChannel

     public string description { get; set; } 
     [XmlElement("Item")] 
     public Page Items { get; set; } 
    } 
    [XmlRoot(ElementName = "rss", Namespace = "http://base.google.com/ns/1.0")] 
    public class Page : List<Item> { } 
    [XmlType("Item")]

     public string link {get; set; } 
     [XmlElement("title", Namespace = "http://base.google.com/ns/1.0")]

     public string price {get; set; } 
     [XmlElement("brand", Namespace = "http://base.google.com/ns/1.0")] 
     public string brand {get; set; } 
     [XmlElement("identifier_exists", Namespace = "http://base.google.com/ns/1.0")] 
     public string identifier_exists {get; set; } 
     [XmlElement("additional_image_link", Namespace = "http://base.google.com/ns/1.0")] 
     public string additional_image_link {get; set; } 
     [XmlElement("google_product_category", Namespace = "http://base.google.com/ns/1.0")] 
     public string google_product_category {get; set; } 
     [XmlElement("product_type", Namespace = "http://base.google.com/ns/1.0")] 
     public string product_type {get; set; } 
     [XmlElement("sale_price", Namespace = "http://base.google.com/ns/1.0")] 
     public string sale_price {get; set; } 
     [XmlElement("sale_price_effective_date", Namespace = "http://base.google.com/ns/1.0")] 
     public string sale_price_effective_date {get; set; } 
    } 
} 

XML头（100％肯定是公形成）：

<?xml version="1.0" encoding="utf-16"?> 
<rss xmlns:g="http://base.google.com/ns/1.0" Version="2.0"> 
    <channel> 
    <title>CatalogFB</title> 
    <link>https://store.playstation.com/#!/en-us</link> 
    <description>All Items in Catalog</description> 
    <Item> 
    .... 

可执行代码：

 FBCatalog.googleRss dataObject = new FBCatalog.googleRss(); 
    using (XmlReader reader = XmlReader.Create(new StringReader(xml.InnerXml))) 
    { 
      var serializer = new XmlSerializer(typeof(FBCatalog.googleRss), "rss"); 
      dataObject = (FBCatalog.googleRss)serializer.Deserialize(reader); 
      GCatalog.Page page = new GCatalog.Page(); 
      counter = 0; 

      foreach (var ITEM in dataObject.Channel.Items) 
      { 
       GCatalog.Item gItem = GCatalog.ConvertToGItem(ITEM); 
       page.Add(gItem); 
      } 
    } 

这件事情正在杀死我，我已经上了好几个小时。

有趣的是，我平时去工具是将我的XML和过去的特殊复制到VS Studio，看看类VS Studio会自动构建反序列化这个。在这种情况下，它与我的代码完全相同。很混乱。

Answer 1

该问题是命名空间之一。 XML中的rss元素位于默认名称空间中，但googleRss上的XmlRoot属性的名称空间为http://base.google.com/ns/1.0。

xmlns:g="..."的名称空间声明将名称空间绑定到前缀g，但这不会在您的问题的XML片段中的任何位置使用。

从XmlRoot属性删除Namespace值：

[XmlRoot(ElementName = "rss")] 
public partial class googleRss 

而且从串行器构造去除rss默认命名空间：

var serializer = new XmlSerializer(typeof(GCatalog.googleRss)); 

的演示中看到this fiddle。

Answer 2

由于utf-16发生错误。只需从StringReader中读取一行即可跳过。

  FBCatalog.googleRss dataObject = new FBCatalog.googleRss(); 
     using (StringReader sReader = new StringReader(xml.InnerXml)) 
     { 
       sReader.ReadLine(); 
       XmlReader reader = XmlReader.Create(sReader); 
       var serializer = new XmlSerializer(typeof(FBCatalog.googleRss), "rss"); 
      dataObject = (FBCatalog.googleRss)serializer.Deserialize(reader); 
      GCatalog.Page page = new GCatalog.Page(); 
      counter = 0; 
      foreach (var ITEM in dataObject.Channel.Items) 
       { 
        GCatalog.Item gItem = GCatalog.ConvertToGItem(ITEM); 
        page.Add(gItem); 
       } 
     }
