反序列化无法填充对象中的元素

试试下面的代码。我做了一些抽查错误，但仍然可能有一些问题。我从一个不同的文件名读取XML，所以你需要回到你原来的文件名。

好的。奇怪。我在不同的开发机器上创建了一个全新的项目，并使用所有干净的XSD->CS和XSD->Sample XML运行了整个过程，这段代码运行得很好。所以我想我删除了这个问题，或者有人可以沿着"重新开始"的路线发布答案。我确定的唯一不同之处是，我将标头标记从XMLSchemaExplorer拖到设计器工作界面，而不是拖到IATA_PASSENGERCONFORMANCEIDENTIFYRQ元素。这产生了一个巨大的分支树，而不是单个节点。这可能会导致问题，但可能会发生其他事情:我怀疑旧项目上的VS2010保留了对早期版本类的引用，或者在备份文件夹中引用了错误的版本。
