Question

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>

通过这个电话：

[...]
    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：

                this.titleField = value;
            }
        }
    }
}

但它引发了错误There is an error in XML document (2, 2)。我现在已经找了一个小时的解决方案了，但是没有多大帮助。

我甚至尝试过一些不应做的事情：

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

然而，这确实可以防止错误发生。但是因为它只实现了将XMLGateResponse.XGResponse实例完全为空（每个元素/属性都为空），所以它并不是真正的改进。

我知道这个问题There is an error in XML document (2, 2)已经讨论了很多，但我真的找不到适合我的解决方案。

Answer 1

如果您尝试反序列化为错误类型，则可能会出现相同的错误例如，如果你打电话

Deserialize<object>(myXml)

或

Deserialize<Failure>(myXml)

我知道回答Q是不好的做法1）答案已经提供，2）答案并不是提问者要求的答案;但是我认为这可能会节省一些时间让其他人在这里找到问题的方式并不像提问者那样。

Answer 2

XGResponse使用XmlRootAttribute进行修饰，指定默认的namspace名称，但文档不会。

删除此命名空间声明或将xmlns="http://tempuri.org/XMLGateResponse"添加到xml的根元素

C＃XML文档中存在错误（2,2）
