问题描述
我有这个程序，我需要它使用我声明的价格乘以客户需要的房间数量乘以他们需要房间的天数.我已经将所有房间价格声明为表单级别变量，并且我需要的所有计算都在计算"区域内(基本上是一个按钮).
当前唯一可以正确计算的房间是标准双人间的大小.我不知道为什么该程序为其他三个房间返回$ 0.任何帮助表示赞赏！
对于其他三个房间，
I have this program and I need it to use the prices I''ve declared multiplied by the number of rooms a customer needs multiplied by the amount of days they need the room(s). I''ve declared all the room prices as form level variables and all the calculations I need are in the region Calculations (basically one button).
Currently the only room that is being calculated correctly is the Standard Double room size. I cannot figure out why the program is returning $0 for the other three rooms. Any help is appreciated!

我看不到代码中实际计算预订房间总费用的任何地方.您将多个未初始化的变量加在一起，然后乘以看起来总为零的天数.您的计算需要计算出客房费用乘以每次预订的天数乘以成人数量(如果适用)的天数.
I don''t see anywhere in your code where you are actually calculating the total cost of the room that is booked. You add a number of uninitialised variables together and multiply by the number of days which looks to provide a total of zero. Your calculation needs to compute the room cost times the number of days times the number of adults (if applicable) for each booking.
如果您跳过启动房价计算的复选框， :
(这些)
If you skip the checkboxes that initiate the calculations of the room rates:
(these)
private void chkStandard_CheckedChanged(object sender, EventArgs e)
{
StandardRate = StandardDoubleRate * numStandard.Value;
}
而是将这些计算结果放入有效的btncalc函数中.
所以btnCalc应该像这样开始:
and instead put these calculations in the btncalc function it works.
so btnCalc should start like this:
public void btnCalc_Click(object sender, EventArgs e)
{
//clears list for neatness each time the room rate is calculated
lstOutput.Items.Clear();
long Days;
decimal CostDays;
StandardRate = StandardDoubleRate * numStandard.Value;
DeLuxeRate = DeLuxeDoubleRate * numDeLuxe.Value;
DoubleRate = LuxuryDoubleRate * numDouble.Value;
KingRate = LuxuryKingRate * numKing.Value;
(除了成为:)的一天)
日期计算应如下所示:
DateOut.Date.Subtract(DateIn.Date).Days
此外，将费率和增值税硬编码到程序中不是一个好习惯. (每次更改速率时，都必须在程序中进行更改并重新编译...)
这些应该来自外部来源-(文件/数据库等)
(well apart from being a day of :) )
the date calculation should look like this:
DateOut.Date.Subtract(DateIn.Date).Days
Furthermore it''s not good practice to have rates + vat hardcoded into the program. (Every time the rate changes you have to change it in the program and recompile...)
These should come from an external source -(file/database etc)
