XML文档（1,2）中存在错误，System.InvalidOperationException：未被预期
从API发送的XML

我正在使用包含AuthorizationData的主体向API发出POST请求。 API应该返回xml以反序列化为firstresponse。 我收到了xml（通过打印到控制台确认），但我收到There is an error in the XML Document(1,2)并且不希望 。 我在这里先向您的帮助表示感谢。
它似乎在抱怨一个意想不到的根元素，并且在你的问题的其他地方存在一些混乱。
在问题标题中，您有
在示例XML响应中，您有
在C＃中你有[XmlRoot(ElementName="AuthorizationResult")]
在您的问题的最后，您提到
这是主题的一些微妙变化。
假设XML样本响应是正确的，您应该更改C＃以期望根元素为
[XmlRoot(ElementName="AuthenticationResult")] public class AuthenticationResult { ...
