c# - 将十进制值转换为小时和分钟；还从另一个中减去两个小时/分钟值

Question

我在 ASP.Net 页面上有两个十进制文本框:

Balance: 200.00 (200 Hrs and 00 Minutes)
TextBox1 = 75.30 (75 Hrs and 30 Minutes)
(After entering the value in TextBox1; the function should calculate the difference between Balance - TextBox1)
TextBox2:  (based on 60 min per hour) = 124.30 (124 Hrs and 30 minutes)

Answer 1

使用 TimeSpan要计算这两个值之间的差异，您必须分别输入小时和分钟。一般来说，我会避免将时间跨度表示为十进制值，更常见的是您将冒号视为分隔符，即 4:30。

//parse hours and minutes from textbox input

TimeSpan t1 = new TimeSpan(hours1, minutes1, 0);
TimeSpan t2 = new TimeSpan(hours2, minutes2, 0);

int deltaHours = (t1 - t2).Hours;
int deltaMinutes = (t1 - t2).Minutes;
