Question

我估计我可以这样做：

Dictionary<string, <Dictionary<int, int>> targetChapterAdjustments = new Dictionary<string, <Dictionary<int, int>>();

（创建一个将Dictionary作为其“定义”成员的词典。）

但是到底能走多远 - 有限制或实际限制吗？

我可以使用这样的词典：

Dictionary<string, <Dictionary<int, Dictionary<string, <Dictionary<int, Dictionary<bool, <Dictionary<float, Dictionary<string, <Dictionary<int>>>>>>>>>>>>

...例如？

我很想/不喜欢看这样一个班级的创作。

好的，LineBacker跟我说话了;我试过了，但是这个：

Dictionary<string, <Dictionary<int, Dictionary<string, <Dictionary<int, Dictionary<bool, <Dictionary<float, Dictionary<string, <Dictionary<int>>>>>>>>>>>> funWithDictionaries = 
    new Dictionary<string, <Dictionary<int, Dictionary<string, <Dictionary<int, Dictionary<bool, <Dictionary<float, Dictionary<string, <Dictionary<int>>>>>>>>>>>>();

...因多个语法错误而失败。

此代码编译。足够你的情况？

Answer 1

C＃或CLR没有强制执行任意限制。您最终会遇到的限制是系统内存，但这适用于创建任何对象，而不仅仅是嵌套结构。

泛型的设计是合理的，无论您提供什么类型参数（假设它们是有效类型），它都将起作用。这意味着任何具体类型都可以替换TKey的{{1}}和TValue部分。我相信预编译器实际上在幕后创建了一个类，具体类型替换了它们相应的Type参数，所以你所做的只是增加它必须做的工作。如果你要构建一个证明，你会发现这种做法对于任何数量的嵌套来说都是合理的（理论上它可能是无限的，当然你在实践中也做不到这一点。）

Answer 2

如果您只是询问资源限制，我认为@ evanmcdonall的答案是正确的，但是如果您关心代码设计，您应该避免使用许多嵌套字典，因为它们违反了许多OOP的良好实践，如抽象和OCP。

字典嵌入其他词典的次数是否有实际限制？
