XML反序列化<RSS的xmlns =「」>預計不會

Question

這些另外一個....

我已經通過堆棧溢出許多其他的例子看了看，還沒有找到一個解決方案，使這項工作。

錯誤：

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. 

對象類：

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 title { get; set; } 
     public string link { get; set; } 
     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 class Item 
    { 
     #region private properties 
     private props..... 
     #endregion 

     #region public propterties 
     [XmlElement("id", Namespace = "http://base.google.com/ns/1.0")] 
     public string id {get; set; } 
     [XmlElement("availabilityid", Namespace = "http://base.google.com/ns/1.0")] 
     public string availability {get; set; } 
     [XmlElement("condition", Namespace = "http://base.google.com/ns/1.0")] 
     public string condition {get; set; } 
     [XmlElement("description", Namespace = "http://base.google.com/ns/1.0")] 
     public string description {get; set; } 
     [XmlElement("image_link", Namespace = "http://base.google.com/ns/1.0")] 
     public string image_link {get; set; } 
     [XmlElement("link", Namespace = "http://base.google.com/ns/1.0")] 
     public string link {get; set; } 
     [XmlElement("title", Namespace = "http://base.google.com/ns/1.0")] 
     public string title {get; set; } 
     [XmlElement("price", 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頭（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> 
    .... 

可執行代碼：

 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); 
      } 
    } 

這件事情正在殺死我，我已經上了好幾個小時。

有趣的是，我平時去工具是將我的XML和過去的特殊複製到VS Studio，看看類VS Studio會自動構建反序列化這個。在這種情況下，它與我的代碼完全相同。很混亂。

Answer 1

該問題是命名空間之一。 XML中的rss元素位於默認名稱空間中，但googleRss上的XmlRoot屬性的名稱空間爲http://base.google.com/ns/1.0。

xmlns:g="..."的名稱空間聲明將名稱空間綁定到前綴g，但這不會在您的問題的XML片段中的任何位置使用。

從XmlRoot屬性刪除Namespace值：

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

而且從串行器構造去除rss默認命名空間：

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

的演示中看到this fiddle。

Answer 2

由於utf-16發生錯誤。只需從StringReader中讀取一行即可跳過。

  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); 
       } 
     }
