来自Goodreads API的Xml反序列化错误（System.InvalidOperationException）

Question

我正在使用goodreads api构建一个应用程序。我运行了以下URI： 的 https://www.goodreads.com/book/title.xml?key=Mykey&title=pride%20and%20prejudice

并获得了Xml文档：

<GoodreadsResponse>
<Request>
<authentication>true</authentication>
<key>
<![CDATA[ MyKey ]]>
</key>
<method>
<![CDATA[ book_title ]]>
</method>
</Request>
<book>
.....
</book>
</GoodreadsResponse>

然后我复制了文档并做了一个特殊的粘贴（粘贴为xml类）来生成模型。

我为模型编写了一个服务类，如下所示：

   public class RecommendationService
{
    public static async Task<Models.RecommendationItem.GoodreadsResponse> GetRecommendationInfo(string title)
    {
        string uri = $"https://www.goodreads.com/book/title.xml?key=my key&title={title}";
        var bookItem = new Models.RecommendationItem.GoodreadsResponse();

        using (var client = new WebClient())
        {
            HttpWebRequest request = WebRequest.Create(uri) as HttpWebRequest;

            XmlSerializer serializer = new XmlSerializer(typeof(Models.RecommendationItem.GoodreadsResponse));
            WebResponse response = request.GetResponse();
            bookItem = (Models.RecommendationItem.GoodreadsResponse)serializer.Deserialize(response.GetResponseStream());
            bookItem.book.title = bookItem.book.title ?? "FAIL";

        }
        return bookItem;
    }

当我为标题运行时，这段代码就像一个魅力一样骄傲和偏见＆＃34;但是当我竞选标题＆＃34; fire and ice＆＃34;时，我得到错误（带有堆栈跟踪）：

我做错了什么？ 有没有办法可以解决这个问题？
