C# 我需要帮助为这个问题创建一个循环

我很难为这个问题创建循环

计算所得税时，应用程序需要累加从所有前一个税级到下一个税级的所有税款 收入的括号如表所示。 另外，您必须使用循环来解决此问题

这就是我目前所拥有的

        int[] upper = { 9525, 38700, 82500, 157500, 200000, 500000, };
        int[] rate = { 10, 12, 22, 24, 32, 35, 37 };
        double tax;
        Write("Please enter your income >> ");
        double income = Convert.ToInt32(ReadLine());

        for (int i = 0; i < upper.Length; i++)
        {
            if (income <= upper[i])
            {
                tax = income * rate[i];

            }

        }

任何帮助都将不胜感激

这个小代码有太多问题

你写的税太多了，而你想把所有税的价值加起来，形成一个所得税

您的条件收入以下是一个独立的静态函数，用于计算所需的结果。虽然这可能不会对练习产生影响，但一般来说，不建议使用浮点数进行货币计算，因为处理大量数据时可能会失去精度；可以转换为最低单位美分或其他任何单位，并使用整数或长数，或者使用小数，如下所示

public static decimal IncomeTax(decimal income)
{
    // Only positive income can be taxed
    if (income <= 0M) return 0M;

    // Initialize bracket limits and rate percentages
    int[] brackets = { 0, 9525, 38700, 82500, 157500,
                       200000, 500000, int.MaxValue };
    int[] rates = { 10, 12, 22, 24, 32, 35, 37 };

    // Start with zero tax
    decimal tax = 0M;

    // Loop over tax rates and corresponding brackets
    for (int i = 0; i < rates.Length; i++)
    {
        // Calculate amount of current bracket
        int currBracket = brackets[i + 1] - brackets[i];

        // If income is below lower bound, exit loop
        if (income < brackets[i]) break;

        // If income is between lower and upper bound,
        if (income < brackets[i + 1])
        {
            // adjust bracket length accordingly
            currBracket = income - brackets[i];
        }

        // Add tax for current bracket to accumulated tax
        tax += (rates[i] / 100M) * currBracket;
    }

    // Return result
    return tax;
}

这看起来像学校的项目！！在这种情况下，您不需要其他人粘贴您的代码，但不要将代码作为图片包含在内。将代码添加到问题中。另外，你的问题也要具体，不要在一篇文章中提出多个问题。这只会给出最后一个税如果你想把所有的税加起来，那么每次都要加上以前的税。你的帮助肯定把我推向了正确的方向。非常感谢你！
