如何获取在c＃从嵌套的字典数据 [英] how to fetch data from nested Dictionary in c#

问题描述

我需要从嵌套词典在C＃中获取数据。我的解释是这样的：

I need to fetch data from nested Dictionary IN C#. My Dictionary is like this:

static Dictionary<string, Dictionary<ulong, string>> allOffset = 
  new Dictionary<string, Dictionary<ulong, string>>();

我要取满字典的所有键/值，表示像这样：

I need to fetch all keys/values of the full dictionary, represented like so:

string->>ulong, string

先谢谢了。

推荐答案

迭代外字典，每次迭代嵌套成员字典，即

Iterate over the outer dictionary, each time iterating members of the nested dictionary, i.e.

（未经测试的代码）

foreach(var key1 in dc.Keys)
{
    Console.WriteLine(key1);
    var value1 = dc[key1];
    foreach(var key2 in value1.Keys)
    {
        Console.WriteLine("    {0}, {1}", key2, value1[key2]);
    }
}
