具有取决于他们的收入和报税身份

Question

在文本文件中欠下的人麻烦diplaying税我无法弄清楚如何做我使用的文本文件里这个税收欠款计算。当我运行程序时，它会显示每个人的收入和申请状态，但所欠的税款不会显示。

class Program 
{ 
    static void Main(string[] args) 
    { 

     Customers.CustomerTax(DataIO.TextFileToString(@"C:\Users\Matt\Desktop\tax.txt")); 

     foreach (Customers item in Customers._taxList) 

     { 

      Console.WriteLine(item.ToString()); 

      FilingStatus fs = (FilingStatus)Enum.Parse(typeof(FilingStatus), "Single"); 
     } 
    } 
} 

这里就是我做我的计算

class Customers 
{ 

    String _marriage; 
    double _income; 
    double _taxOwed; 
    private FilingStatus _filingstatus; 

    public static List<Customers> _taxList = new List<Customers>(); 



    public Customers(String marriage, int income) 
    { 
     Income = income; 
     Marriage = marriage; 

    } 

    public String Marriage 
    { 
     get { return _marriage; } 
     set 
     { 

      _marriage = value; 

     } 
    } 



    public double Income 
    { 
     get { return _income; } 
     set 
     { 
      if (value <= 0) 
      { 
       throw new ArgumentException(String.Format("{0} must be > 0", value)); 
      } 
      _income = value; 

     } 
    } 

    public double CalculateTax() 
    { 
     double taxOwed = 0.0; 

     if (_filingstatus == FilingStatus.Single) 
     { 
      if (Income <= TaxCalculations.Single10) 
      { 
       taxOwed = .1 * Income; 
      } 

      else if (Income <= TaxCalculations.Single15) 
      { 
       taxOwed = .15 * Income; 
      } 
      else if (Income <= TaxCalculations.Single25)

      } 
      else if (Income <= TaxCalculations.Single35) 
      { 
       taxOwed = .35 * Income; 
      } 
      else Console.WriteLine("Derp"); 
     } 
     else if (_filingstatus == FilingStatus.MarriedJoint)

    public static void CustomerTax(String s) 
    { 

     String[] customersArr = s.Split('\n'); 

     foreach (string item in customersArr) 
     { 
      if (item.Equals("")) continue; 

      String[] customer = item.Split(','); 
      Customers p = new Customers(customer[1], int.Parse(customer[0])); 
      _taxList.Add(p); 


     } 
    } 
     public override string ToString() 
     { 
      return String.Format("Income: {0} Marriage Status: {1} Tax Owed: {2}", _income, _marriage, _taxOwed); 

     } 
    } 
} 

的StreamReader，数据IO

class DataIO 
{ 
    public static String TextFileToString(String path) 
    { 
     String output = ""; 
     String record = ""; 
     using (StreamReader sr = new StreamReader(path)) 
     { 

      while ((record = sr.ReadLine()) != null) 
      { 
       output += record + "\n"; 
      } 
     } 
     return output; 
    } 
}

或许这与你的ToString函数有问题吗？

public override string ToString() 
{ 
    return String.Format("Income: {0} Marriage Status: {1} Tax Owed:", _income, _marriage, _taxOwed); 
} 

应该是这样的： 添加您的括号在格式字符串中的第三个参数？

public override string ToString() 
{ 
    return String.Format("Income: {0} Marriage Status: {1} Tax Owed: {2}", _income, _marriage, _taxOwed); 
}
