C＃LINQ轉換查詢字典

Question

A C＃中的查詢轉換字典：

public class myClass 
{ 
    public int my_id; 
    public Dictionary<string, Dictionary<string, string[]>> myDict; 
} 

Dictionary<string, myClass> dataDict; 

Dictionary<int, Dictionary<string, myClass>> query = (from happen in dataDict 
        group happen by happen.Value.my_id into g 
        select g).ToDictionary(??); 

我不知道我應該放什麼（??）。

Answer 1

試試這個：

var query = (from happen in dataDict 
      group happen by happen.Value.my_id into g select g) 
      .ToDictionary(g => g.Key, g => g.ToDictionary(x => x.Key, x => x.Value));
