c#使用操作员进行计算（净薪酬）（总薪酬）

我不明白是否计算了

netPay=grossPay-（fedtax预扣税+社会保障税预扣税）

。我的计算在程序中正确吗？在

editedTax

中处理此类问题？？如果有人能帮忙，我会很感激的

更多信息：当我在输出中显示

netPay

时，我收到一个运行时错误，无法使用

{0:c2}

netPay

在代码中分配的值与您下面的描述相反。
我没有看到任何语法错误或任何东西

---

你有什么问题？您尝试过的一些方法是什么？

我不确定您到底想要什么，但赋值语句中的简单替换会产生以下公式：

自

然后

意义

netPay = grossPay * (FED_TAX + SS_TAX - 1);

所以这里似乎有点不对劲

---

你确定你不想要吗

netPay = grossPay - (editedTax1 + editedTax2);

而不是

netPay = editedTax1 + editedTax2 - grossPay;

这似乎符合你的要求

netPay = grossPay - (FED_TAX * grossPay + SS_TAX * grossPay);

或

…当然，除非我遗漏了什么

---

编辑：我遗漏了一些东西。你的税收常数是百分之一，但当你用它们进行计算时，你不能除以100。您有两个选择：

在计算中使用值时除以100，如：

editedTax1=（联邦税/100）*grossPay

将常数存储为十进制表示形式，而不是百分比，如：

const double FED_TAX=.0028

---

你在计算中得到负数的原因是因为你的SSU税是7.65。我想你想要的数字是0.0765。

我已经在我的机器上测试了这段代码，它工作正常：

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication5
{
    class Program
    {
        static void Main(string[] args)
        {
            const double FEDERAL_TAX_RATE= 0.28;
            const double SOCIAL_SECURITY_RATE = 0.0765;  // I am assuming the 7.65 was supposed to be 7.65%... therefore it should be 0.0765

            Console.WriteLine("       WEEKLY PAYROLL INFORMATION");
            Console.WriteLine("       --------------------------");
            Console.Write("\n       Please enter the employer's name: ");
            string empName = Console.ReadLine();
            Console.Write("\n       Please enter the number of hours worked this week: ");
            double hrsWorked = Convert.ToDouble(Console.ReadLine());
            Console.Write("\n       Please enter the number of OVERTIME HOURS worked this week: ");
            double ovtWorked = Convert.ToInt32(Console.ReadLine());
            Console.Write("\n       Please enter employee's HOURLY PAY RATE: ");
            double payRate = Convert.ToDouble(Console.ReadLine());
            double grossPay = CalculateGrossPay(hrsWorked, payRate, ovtWorked);
            double federalTaxWithheld = CalculateTax(grossPay, FEDERAL_TAX_RATE);
            double socialSecurityWithheld = CalculateTax(grossPay, SOCIAL_SECURITY_RATE);
            double netPay = CalculateNetPay(grossPay, federalTaxWithheld + socialSecurityWithheld);

            Console.WriteLine("\n\n       The weekly payroll information summary for: " + empName);
            Console.WriteLine("\n       Gross pay:                             {0:C2}    ", grossPay);
            Console.WriteLine("       Federal income taxes witheld:          {0:C2}      ", federalTaxWithheld);
            Console.WriteLine("       Social Security taxes witheld:         {0:C2}    ", socialSecurityWithheld);
            Console.WriteLine("       Net Pay:                               {0:C2}", netPay);

            Console.ReadLine();  // You don't need this line if your running from the command line to begin with
        }

        static double CalculateGrossPay(double HoursWorked, double PayRate, double OvertimeHoursWorked)
        {
            return PayRate * (HoursWorked + 1.5 * OvertimeHoursWorked);
        }

        static double CalculateTax(double GrossPay, double TaxRate) 
        {
            return GrossPay * TaxRate;
        }

        static double CalculateNetPay(double GrossPay, double TaxAmount)
        {
            return GrossPay - TaxAmount;
        }
    }
}

由于这似乎是您的第一门编程课程，我将为您提供一些他们在课堂上可能不会强调的要点：

• 使用描述性变量名。如果您注意到自己在变量名后面加了一个数字，它可能会以一种不同的、更可读的方式完成
• 利用函数，它们将常见任务捆绑在一段代码中，并显著提高可读性
• 您可能希望在此代码中添加一些或验证。例如，如果您意外地将

我知道这在您的编程过程中可能并不重要，但开始时最好使用编码技术，使您的代码更易读、更容易混淆，特别是对于将来可能需要维护代码的人。

您可能希望将editedTax1和editedTax2重命名为federalTax和socialSecurityTax，或者类似的东西。这将使代码更容易阅读。我很好奇为什么这个问题被否决。请解释一下？因为问题没有澄清，只是“这是我的公式，但我懒得把它复制到程序中”@Brent，我试图产生你提到的运行时错误。您在程序中使用了哪些输入？我想要第一个输入，netPay=grossPay-（editedTax1+editedTax2）；但是当我在输出中显示它时，我发现了一个运行时错误，我不能用{0:c2}将负数转换为货币。这两个语句应该给出不同的答案，对吗？特别是在不同的输入上？这两个语句正好相反，除非grossPay为零，否则会给出不同的答案。这与3-2=1和2-3=-1是一样的。其次，我再次查看了您的代码，找到了负数的原因。答案已编辑。我希望在标记为“家庭作业”的帖子上有一个否决票选项。但是你应该赢得家庭作业救世主的徽章，吉姆。很抱歉，如果我没有其他选择来提高我的编程知识的话。@Philoushka:我们都遇到过这样的情况，我们离问题太近了，看不到明显的问题，需要一些帮助。这不像是他让我们为他做任务。我们在我工作的地方遇到过很多次这个问题。。。如果联邦税率为28%，则正确为0.28%。那么，为什么社会保障税是765%？如果是7.65%，那么你想要的数字实际上是0.0765。

netPay = grossPay - (FED_TAX * grossPay + SS_TAX * grossPay);

netPay = grossPay * (1 - (FED_TAX + SS_TAX));
