直列化解除エラー： "<book xmlns = ''>は予期していませんでした。 xml文字列からDeSerialize

Question

xmlを複数のクラスオブジェクトにデシリアライズする際に問題が発生しています。私がデシリアライズしようとするとき 私は "期待されていませんでした。私は、この内部例外を取得し、このコードを実行しようとすると、ここで

は私の呼び出し元のコードが

StringReader strReader = new StringReader(xml);   
XmlTextReader reader = new XmlTextReader(strReader); 
reader.ReadToDescendant("book"); 
var temp = DeserializeFromXml<book>(reader.ReadOuterXml()); 

public static T DeserializeFromXml<T>(string xml) 
    { 
     T result; 
     XmlRootAttribute xRoot = new XmlRootAttribute(); 
     XmlSerializer ser = new XmlSerializer(typeof(T)); 
     using (TextReader tr = new StringReader(xml)) 
     { 
      result = (T)ser.Deserialize(tr); 
     } 
     return result; 
    } 

されるXMLは、文字列メッセージ

<?xml version="1.0" encoding="UTF-8"?><books xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > 
<book genre="novel"> 
    <title>The Handmaid's Tale</title> 
    <price>19.95</price> 
    <ISBN>1-861003-78</ISBN> 
    <style>hardcover</style> 
</book> 
<library genre="novel"> 
    <name>Oxford</name> 
    <location>london</location> 
    <ISBN>1-8888888-88</ISBN> 
    <address>12th main, chesmedia</address> 
</library> 

である "予想されなかったの。"

単にあなたBookクラスの属性から名前空間=を脱ぎます。 コードは
