使用LINQ读取分隔文件

using System;
using System.IO;
using System.Linq;

class Program
{
    static void Main(string[] args)
    {
        var filePath = @"C:\data.csv";
        var separator = ',';

        var lines = File.ReadAllLines(filePath);
        var headers = lines.First().Split(separator);

        var data = lines.Skip(1)
            .Select(line => line.Split(separator))
            .Select(items => headers.Zip(items, (header, item) => new { header, item }))
            .Select(items => items.ToDictionary(x => x.header, x => x.item));

        foreach (var item in data)
        {
            Console.WriteLine(item);
        }
    }
}
