直接写貌似不行，怎么写好呢？

[以专业开发人员为伍]

什么叫做“转”？你的集合中的对象原本就是 Dictionary<,>的，那么直接写这类代码

var lst = (from x in List select (Dictionary<string,.....>)x).ToList();

就可以了。 在编程中，不应该滥用 object 这个关键字。应该强类型，面向明确的业务接口（父类）编程设计。尽可能地用具体化接口（父类）编程，这才真正懂得抽象化设计的人。

list.Select(x => x.ToDirectiory(y => x.xxx, y => y.yyy)).ToList()

迫不得已啊，游戏客户端与服务端接口对接设计成这样的，因为有不同的类型数据传入，所以统一设计成了object
