用C＃替代嵌套有序词典？

问题描述

我正在开发的程序遇到问题。该程序的基本本质是浏览选举数据文件并通过嵌套对象进行组织。例如，每个单独的“政治种族”都是一个对象，每个“政治种族”对象都有一个“候选人”和“县结果”对象的列表，等等。

我当前的问题与前面提到的“县结果”对象有关。我应该遍历文件，并记录候选人的姓名和他们为每个县获得的票数。目前，我正在使用嵌套的有序词典来实现此目的，但是似乎很笨拙，并且在访问它们时遇到了问题。到目前为止，这是我的代码（listOrdicRows是将选举的文本文件读入有序列表）：

public CountyResults(List<OrderedDictionary> listOrdicRows,String raceCode)
{
    foreach (OrderedDictionary row in listOrdicRows)
    {
        bool duplicate = false;
        foreach (County indivCounty in CountyList)
        {
            if (indivCounty.countyName == row["county_name"].ToString() && raceCode == row["race_code"].ToString())
            {
                duplicate = true;
                break;                            
            }
        }
        if (!duplicate && raceCode == row["race_code"].ToString())
        {
            CountyList.Add(new County(row["county_code"].ToString(),row["county_name"].ToString(),row["precincts"].ToString(),row["precincts_reporting"].ToString()));
        }
    }
    populateCountyDict(listOrdicRows);          
}

public void populateCountyDict(List<OrderedDictionary> listOrdicRows) //Dynamically populates County Dictionary
{
    foreach (County x in CountyList)
    {
        String CountyName = x.countyName;
        List<OrderedDictionary> candidatesWithVotes = null;
        foreach (OrderedDictionary row in listOrdicRows)
        {
            if (CountyName == row["county_name"].ToString())
            {
                OrderedDictionary tempDictionary = new OrderedDictionary();
                tempDictionary.Add(row["candidate_name"],row["total_votes"]);
                candidatesWithVotes.Add(tempDictionary);
            }
        }
        countyDict.Add(CountyName,candidatesWithVotes);
    }
}

任何帮助将不胜感激，因为我被困住了。有人问文件是什么样子，这是几行

解决方法

Linq可以使其变得简单易读。

我已经创建了一个仅几列的示例文件

接下来是代码

   public class ElectionInfo
    {
        public string Race { get; set; }
        public string County { get; set; }
        public string FName { get; set; }
        public int VoteCnt { get; set; }
    }

    static void Main(string[] args)
    {
        Dictionary<string,List<ElectionInfo>> dict1 = File.ReadAllLines(@"C:\x1\TextFile2.txt")
        .Select(record => record.Split(','))
        .Select(cell => new ElectionInfo() { Race = cell[0],County = cell[1],FName = cell[2],VoteCnt = int.Parse(cell[3]) })
        .GroupBy(x => x.Race)
        .ToDictionary(t => t.Key,t => t.ToList<ElectionInfo>())
        ;
