Question

我是c＃的新手，我正在尝试打印收据，但我的代码无效。这是我的问题：

计算价格乘以用户提供的数量
计算上述金额 - 12％税收显示增值税接受款项
计算一旦输入单价后所有出现的变化

这是我目前的计算部分代码

bool test = false;
do
{
    try
    {
        Console.SetCursorPosition(2, 12);
        Console.Write(" ");

        Console.SetCursorPosition(2, 12);
        Num = Convert.ToInt32(Console.ReadLine());
        test = false;
    }
    catch
    {
        test = true;
    }
} while (test);

Console.SetCursorPosition(18, 12);
Console.ForegroundColor = ConsoleColor.Yellow;
telNumber = Console.ReadLine();

//Peso

bool Ptest = false;
do
{
    try
    {
        Console.SetCursorPosition(47, 12);
        Console.Write(" ");
        Console.SetCursorPosition(47, 12);
        Amount = Convert.ToInt32(Console.ReadLine());
        Console.SetCursorPosition(65, 12);
        Amount = Amount * 2 ;

        Console.WriteLine("P " + Amount.ToString("0.00"));

        Console.SetCursorPosition(65, 15);
        Console.ForegroundColor = ConsoleColor.Green;
        Console.WriteLine("P " + Amount.ToString("0.00"));

        Console.SetCursorPosition(65, 17);
        Console.ForegroundColor = ConsoleColor.Green;
        Console.WriteLine("P " + Amount.ToString("0.00"));

        Ptest = false;
    }
    catch
    {
       Ptest = true;
    }
} while (Ptest);

//Amount

Console.ReadLine();

它必须看起来像这样，我已完成格式但我遇到上述问题时遇到问题，请帮忙

使用小数而不是整数32.

       bool test = false;
        do
        {
            try
            {
                Console.SetCursorPosition(2, 12);
                Console.Write(" ");

                Console.SetCursorPosition(2, 12);
                Num = Convert.ToDecimal(Console.ReadLine());
                test = false;
            }
            catch
            {
                test = true;
            }
        } while (test);

        Console.SetCursorPosition(18, 12);
        Console.ForegroundColor = ConsoleColor.Yellow;
        telNumber = Console.ReadLine();

        bool Ptest = false;
        do
        {
            try
            {
                Console.SetCursorPosition(47, 12);
                Console.Write(" ");
                Console.SetCursorPosition(47, 12);
                Amount = Convert.ToDecimal(Console.ReadLine());
                Console.SetCursorPosition(65, 12);
                Amount = Amount * 2;

                Console.WriteLine("P " + Amount.ToString("0.00"));

                Console.SetCursorPosition(65, 15);
                Console.ForegroundColor = ConsoleColor.Green;
                Console.WriteLine("P " + Amount.ToString("0.00"));

                Console.SetCursorPosition(65, 17);
                Console.ForegroundColor = ConsoleColor.Green;
                Console.WriteLine("P " + Amount.ToString("0.00"));

                Ptest = false;
            }
            catch
            {
                Ptest = true;
            }
        } while (Ptest);

        //Amount

        Console.ReadLine();
