C# 实现IEnumerator的类上的序列化

我已经写了一个程序，它将序列化和反序列化，它做得很好（我计划在子类上实现它，一旦我得到正确的工作在一个）。然而，当我决定使用

Foreach

迭代结果时，我遇到了麻烦

在这不起作用之后，我发现必须实现

IEnumerator

和

IEnumerable

接口，并将所需的方法添加到我的类中。所以我有，这确实允许我循环我的收藏

当我尝试将这两件事结合起来时，问题就开始了

序列化时，我最初遇到以下错误：

内部：

{“TheResonlyRules.Army的类型不是预期的。请使用XmlInclude或SoapInclude属性指定静态未知的类型。”}

我将

[xmlclude（typeof（Employee））]

添加到我的类中以防止此异常，但现在前两个根元素被称为

，而不是

。我不知道如何将它们更改回

[XmlRoot（“任意”）]

，因为某些原因没有效果

反序列化时，我收到此错误

{“XML文档（0，0）中存在错误”。}

内部：

{“缺少根元素”。}

我已经搜索过了，但似乎这个错误可以通过多种不同的方式产生。我还没有找到任何适用于我的代码的解决方案（据我所知）

我非常感谢您提供一些关于我遇到的这些问题的原因或解决方案的信息
