将xml序列化为c#对象答案

【问题标题】：Serialize xml to c# object将xml序列化为c#对象
【发布时间】：2019-10-18 11:34:33
【问题描述】：

我在尝试将我的 XML 序列化为 C# 对象时遇到了一些问题。我收到多个“System.InvalidOperationException”。

错误：

InvalidOperationException：反映属性“MPFAvailability”时出现错误。
InvalidOperationException：反映类型“TalkTalkAPI.Models.AvailabilityDetails”时出现错误。
InvalidOperationException：反映属性“AvailabilityContent”时出现错误。
InvalidOperationException：反映类型“TalkTalkAPI.Models.AvailabilityContent”的错误。

我查看了内部异常，但不存在更多细节。我确信这与我的对象的设置方式有关。

        Availability result;

        // Deserialises xlm into an object 

        XmlSerializer serializer = new XmlSerializer(typeof(Availability));
        using (TextReader reader = new StringReader(formatedXml))
        {
            result = (Availability)serializer.Deserialize(reader);
        }

        return result;

【问题讨论】：

最简单的可能是构造一个对象，然后将其序列化为 XML 并查看与示例 xml 的差异。
也许你需要所有类的 [Serializable] 属性

标签： c# xml soap

【解决方案1】：

这个 XML 名称出现了两次：

[XmlElement("EstimatedThroughputSpeedAnnexA")]

我发现它有这个内部异常：

InvalidOperationException: The XML element 'EstimatedThroughputSpeedAnnexA' from namespace '' is already present in the current scope. Use XML attributes to specify another XML name or namespace for the element.

（如果您不需要，最好不要使用 XmlElement 属性！）
