Question

我做错了什么？我试图让我的程序从csv文件读取数据，但我一直得到这个未处理的异常，是因为我如何编写txt文件？例外？

首先，我尝试将数据显示为控制台中的列表，但这也没有发生。我似乎无法在这里做到这一点，甚至可以从我的txt文件中读取它。

namespace PracticeProgram

public class Program
{
    public static bool W2 { get; private set; }

    public static void Main(string[] args)
    {            
        List<Person> myContacts = new List<Person>();

        // Loop to collect developers data
        for (int i = 0; i < 4; i++)

         {
            Console.WriteLine("Welcome developer, enter your name to continue");
            string name = Console.ReadLine();
            Console.WriteLine("Hello, " + name);

            Console.WriteLine("enter your address");
            string address = Console.ReadLine();
            Console.WriteLine(address);

            Console.WriteLine("enter your monthly income");
            double GrossMonthlyPay = 5000;
            Console.WriteLine(GrossMonthlyPay);
            Console.ReadLine();

            Console.WriteLine("your tax deduction is set at 7%");
            double taxes = (0.07);
            Console.WriteLine(taxes);
            Console.ReadLine();

            Console.WriteLine("your monthly tax deduction is ");
            Console.WriteLine(taxes = GrossMonthlyPay * taxes);
            Console.ReadLine();

            Console.WriteLine("Based on your monthly income your Annual gross pay is ");
            double AnnualGrossPay = GrossMonthlyPay * 12;
            Console.WriteLine(AnnualGrossPay);
            Console.ReadLine();

            Console.WriteLine("Your annual taxes are ");
            double AnnualTaxes = AnnualGrossPay * 0.07;
            Console.WriteLine(AnnualTaxes);
            Console.ReadLine();

            Console.WriteLine("Select 1 for W2, select 2 for 1099");
            bool A = W2;
            Console.WriteLine();
            Console.ReadLine();

    internal void SerializeToCSV(string v)

}

this is the error
