C# 我得到的错误是；System.ArgumentException:'；路径中的非法字符。'&引用；在反序列化XML时

我正在尝试使用XML反序列化将来自API的大型XML响应解析为C#对象，但在System.ArgumentException中出错：“路径中的非法字符”

我试过的代码如下

// XML Response from API is stored in xml variable
string xml = Response.Content;
XmlSerializer deserializer = new XmlSerializer(typeof(AmazonEnvelope));
TextReader reader = new StreamReader(xml);
object obj = deserializer.Deserialize(reader);
AmazonEnvelope XmlData = (AmazonEnvelope)obj;
reader.Close();

基于XML响应的类下面创建这些类以便进行反序列化
