想要使用SOLID“O”重构C＃代码。原则 [英] Want to refactor C# code using SOLID "O" principles

问题描述

want to write this code in simplified way using SOLID principles. Any help would be highly appreciated.Can i implement inheritance to do this.

void CalculateTaxAndRewardPoints()
        {
            if (state == TEXAS)
            {
                rate = TX_RATE;
                amt = baseRate * TX_RATE;
                calc = 2 * basis(amt) + extra(amt) * 1.05;
            }
            else if ((state == OHIO) || (state == MAINE))
            {
                if (state == OHIO)
                    rate = OH_RATE;
                else
                    rate = MN_RATE;
                amt = baseRate * rate;
                calc = 2 * basis(amt) + extra(amt) * 1.05;
                if (state == OHIO)
                    points = 2;
            }
            else
            {
                rate = 1;
                amt = baseRate;
                calc = 2 * basis(amt) + extra(amt) * 1.05;
            }
        }

我的尝试：

What I have tried:

void CalculateTaxAndRewardPoints()
        {
            while (state == TEXAS)
            {
                rate = TX_RATE;
                amt = baseRate * TX_RATE;
                calc = 2 * basis(amt) + extra(amt) * 1.05;
            }
            do while ((state == OHIO) || (state == MAINE))
            {
                while (state == OHIO)
                    rate = OH_RATE;
                else
                    rate = MN_RATE;
                amt = baseRate * rate;
                calc = 2 * basis(amt) + extra(amt) * 1.05;
                do while (state == OHIO)
                    points = 2;
            }
            Do while
            {
                rate = 1;
                amt = baseRate;
                calc = 2 * basis(amt) + extra(amt) * 1.05;
            }
        }
