查询词典的词典？ [英] Query a Dictionary of Dictionaries?

问题描述

请你能告诉我如何查询词典的词典，和/或清单字典？

Please can you advise me on how to query a Dictionary of Dictionaries, and/or a Dictionary of List?

private Dictionary<string, Dictionary<DateTime, double>> masterDict= new Dictionary<string, Dictionary<DateTime, double>>();

Private Dictionary<string, List<DateTime>> masterList= new Dictionary<string, List<DateTime>>();

我知道，如果我这样做，我得到包含在masterDict的词典列表，但我不知道如何让那些字典的值。

I know if I do the following, I get a list of the dictionaries contained in masterDict, but I'm not sure how to get at the values of those dictionaries.

 foreach (var kvp in masterDictMethod())
        {
            Console.WriteLine("Key = {0}, Value = {1}",
                kvp.Key, kvp.Value);
        }

感谢您寻找;）

Thanks for looking ;)

推荐答案

在你的foreach kvp.Value 是每个masterDict入口即词典＆LT;日期时间，双＆GT;

In you foreach kvp.Value is the inner dictionary of every masterDict entry i.e. Dictionary<DateTime, double>

所以，也只是foreach的， kvp.Value ，你会得到的内在价值。

So, just foreach also over kvp.Value and you will get the inner values.

例如。

foreach (var kvp1 in masterDictMethod())
{
   Console.WriteLine("Key = {0}, Inner Dict:", kvp1.Key);
   foreach (var kvp2 in kvp1.Value)
   {
      Console.WriteLine("Date = {0}, Double = {1}", kvp2.Key, kvp2.Value);
   }
}
