C# XML 文档 (2， 2) 中存在错误

我正在尝试反序列化以下XML：

<?xml version="1.0" encoding="UTF-8"?>
<XGResponse><Failure code="400">
    Message id &apos;1&apos; was already submitted.
</Failure></XGResponse>

通过此电话：

[...]
    var x = SerializationHelper.Deserialize<XMLGateResponse.XGResponse>(nResp);
[...]        
public static T Deserialize<T>(string xml)
{
    using (var str = new StringReader(xml))
    {
        var xmlSerializer = new XmlSerializer(typeof(T));
        return (T)xmlSerializer.Deserialize(str);
    }
}

获取相应类的实例：

        }
    }
}

但它提出了错误There is an error in XML document (2, 2).
我已经寻找了大约一个小时的解决方案，但它没有多大帮助。

我什至尝试了一个不应该做任何事情的轻微更改：

public static T Deserialize<T>(string xml)
{
    [...]
        var xmlSerializer = new XmlSerializer(typeof(T), new XmlRootAttribute(typeof(T).Name));
    [...]
}

但是，这确实可以防止错误发生。但是由于它只能向我返回一个完全空的XMLGateResponse.XGResponse实例(每个元素/属性都是空的(，因此这并不是真正的改进。

我知道这种问题There is an error in XML document (2, 2)已经讨论了很多，但我真的没有找到适合我的解决方案。
