如何将两个LIst结合到字典

问题描述

我有两个列表Lst1< string>和Lst2< string>

I have two lists Lst1<string> and Lst2<string>

Lst1                                         Lst2

auto - 1q                                    n122
auto - 2q                                    n341
auto - 3q                                    n461

bus- 1q                                      n132
bus- 2q                                      n441
bus- 3q                                      n761

我想成为:

I want that''s become :

auto
    n122
    n341
    n461

bus
    n132
    n441
    n761

如何使用

How make it with

Dictionary<string, List<string>> axxx = new Dictionary<string, List<string>>();

推荐答案

void Main()
{
    List<string> list1 = new List<string>(){"auto - 1","auto - 2","auto - 3","bus - 4","bus - 5","bus - 6"};
    List<string> list2 = new List<string>(){"n122","n341","n461","n132","n441","n761"};
    Dictionary<string, List<string>> refDic = new Dictionary<string, List<string>>();
    foreach(string item in list1){
        string[] keyInd=item.Split(new char[]{'-'});
        int ind = int.Parse(keyInd[1].Trim())-1;
        string refValue = ind < list2.Count ?
                list2[ind] : string.Empty;
        List<string> refValues;
        if (!refDic.TryGetValue(keyInd[0].Trim(),out refValues)){
            refValues = new List<string>();
            refDic.Add(keyInd[0].Trim(),refValues);}
        refValues.Add(refValue);
    }
}
//The contents of refDic will look like
//Key - auto
//Value - List<string> of
//n122
//n341
//n461
//
//Key - bus
//Value - List<string> of
//n132
//n441
//n761
