在其他詞典中可以嵌入詞典的次數有實際限制嗎？

Question

我認為我可以這樣做：

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

（創建一個以Dictionary為“ Definition”成員的Dictionary）。

但是，這能走多遠？有沒有設定的極限，還是實際的極限？

我可以有一個像這樣的字典：

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

...例如？

我希望/討厭看到這樣一個班級的樣子。

更新

好吧，LineBacker讓我參與其中； 我嘗試了，但是：

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>>>>>>>>>>>>();

...由於多個語法錯誤而失敗。

這段代碼會編譯。 夠您的情況了嗎？

var dict = new Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<str

Answer 1

C＃或CLR沒有強制實施任何限制。 您最終會遇到的限制是系統內存，但這將適用於創建任何對象，而不僅僅是嵌套結構。

泛型的設計是合理的，並且無論您提供什么Type參數（假設它們是有效類型）都可以使用。 意味着任何具體類型都可以替換Dictionary<TKey, TValue>的TKey和TValue部分。 我相信預編譯器實際上是在幕后創建一個類，用具體的類型替換其對應的Type參數，因此您要做的只是增加它必須做的工作。 如果要構造一個證明，您會發現對於任何數量的嵌套來說，這種做法都是正確的（理論上，它可以是無限的，當然，您不能在實踐中這樣做）。

Answer 2

如果您只是詢問資源限制，我認為@evanmcdonall的答案是正確的答案，但是如果您關心代碼設計，則應避免使用許多嵌套的字典，因為它們違反了許多OOP的好習慣，例如抽象和OCP。
