假设我有两种字典：
Dictionary<A, List<C>> Dictionary<B, List<C>> 我想将第二个合并到第一个中。就像是：
Dictionary<A, Dictionary<B, List<C>>。在Linq中最好的方法是什么？
感谢您的帮助！

EDIT1： 考虑以下示例： `
public enum GameCategory
{
FPS,
RPG,
STRATEGY
}
public class Game
{
// The format is: "CountryName,CompanyName,TeamName,GameName"
public string Name { get; set; }
public DateTime InitialReleaseDate { get; set; }
public GameCategory Category { get; set; }
}
public class GameManager
{
// CodeName is coming from Name once Substring applied.
// This dictionary is just all the games grouped by this CodeName
// eg if we have Game1 with name: "USA:Test:MyTeam:GoodGame" & Game2 with: "USA:Test:AnotherTeam:AnotherGame"
// The codeName for both is: "USA:Test" so they are in the same list of dict1
Dictionary<string, List<Game>> _gameByCodeName;
// It is just a grouped by GameCategory
Dictionary<GameCategory, List<Game>> _gameByCategory;
// Expected output
// The goal is just to have the two granularity in one data structure
// In the above example it will be all the games that have the same CodeName and are in the same category
Dictionary<string, Dictionary<GameCategory, List<Game>>>
}
