Question

我一直在研究一个我想进行简单计算的问题。我对C＃很陌生，但我正在努力学习。

基本上，在给出四种不同的输入数据的情况下，我可以节省多少钱：所需收入，税率，估计收益率和每期收入。

我使用一组单选按钮来选择每个时间段的收入，基本上是每日，每周，每月，每年的收入。因此，单选按钮选择如何将收入列为值，但我不确定如何将此部分的变量放入计算部分。我将提供一个代码段。

任何帮助将不胜感激，谢谢。

   private void radioButton2_CheckedChanged(object sender, EventArgs e)
    {
        // Local variables
        decimal income;
        // Get the income, tax rate and rate of return.
        income = decimal.Parse(incomeDesiredTextBox.Text);

        // Determine pay period
        if (true)
        {
            if (incomePerDayRadioButton.Checked)
            {
                decimal newIncome = income / 365;
                return;
            }
            else if (incomePerMonthRadioButton.Checked)
            {
                decimal newIncome = income / 24;
                return;
            }
            else if (incomePerWeekRadioButton.Checked)
            {
                decimal newIncome = income / 52;
                return;
            }
            else if (incomePerYearRadioButton.Checked)
            {
                decimal newIncome = income / 1;
                return;
            }
        }
    }

    private void calculateButton_Click(object sender, EventArgs e)
    {
        // Local variables
        decimal income;
        decimal newIncome;
        decimal taxRate;
        decimal rateOfReturn;

        // Get the income, tax rate and rate of return.
        income = decimal.Parse(incomeDesiredTextBox.Text);
        taxRate = decimal.Parse(totalTaxesTextBox.Text);
        rateOfReturn = decimal.Parse(rateOfReturnTextBox.Text);


        //change rate of return to decimal format
        var rateOfReturnPercentage = rateOfReturn / 100;

        // Calculate Nest Egg.
        decimal taxedIncome = newIncome * taxRate;



    }

Answer 1

你应该创建一个计算新收入的单独方法。

public decimal CalculateNewIncome()
{
        decimal income;
        // Get the income, tax rate and rate of return.
        income = decimal.Parse(incomeDesiredTextBox.Text);

        if (incomePerDayRadioButton.Checked)
        {
            return income / 365;
        }
        else if (incomePerMonthRadioButton.Checked)
        {
            return income / 24; // should be 30 ?
        }
        else if (incomePerWeekRadioButton.Checked)
        {
            return income / 52;
        }
        else if (incomePerYearRadioButton.Checked)
        {
            return income;
        }
}

然后你可以做计算

private void calculateButton_Click(object sender, EventArgs e)
{
    // Local variables
    decimal income;
    decimal newIncome = CalculateNewIncome();
    decimal taxRate;
    decimal rateOfReturn;

    // Get the income, tax rate and rate of return.
    income = decimal.Parse(incomeDesiredTextBox.Text);
    taxRate = decimal.Parse(totalTaxesTextBox.Text);
    rateOfReturn = decimal.Parse(rateOfReturnTextBox.Text);


    //change rate of return to decimal format
    var rateOfReturnPercentage = rateOfReturn / 100;

    // Calculate Nest Egg.
    decimal taxedIncome = newIncome * taxRate;

    // display it
}

C＃，在表单中实现单选按钮来计算Nest Egg
