C＃：秒到几分钟到几小时的转换？ [英] C# : Seconds to Minutes to Hours conversion?

问题描述

好了第一关，我敢肯定，我不希望使用时间跨度为这项任务;而一个公式一系列显示秒，分，并在消息框中小时，当用户输入的文本框中的秒数。

这里就是我卡住。我们应该检查我们的答案的例子：7565秒为2小时，6分，5秒。然而，我的代码最终计算作为2个小时，6分钟，和6秒。这也使这个问题的答案时，最初数量为7560秒。我很困惑！！它是一个条件的情况下，在该消息框显示，只有当用户在60秒进入秒，如果只分钟+秒用户输入秒60和3600之间，和小时±分钟±秒如果输入超过3600秒。这里是我到目前为止，我会很感激任何见解，为什么我的计算是关闭的：）

感谢您的答案！但7565不是一个常数;用户可以输入任何秒金额，但我的教授用7565为例来检查，如果我们在正确的轨道上。

 私人无效calculateButton1_Click（对象发件人，EventArgs五）
 {
 INT totalSeconds，小时，分钟，minutesRemainder，hoursRemainderMinutes，hoursRemainderSeconds; 
 totalSeconds = int.Parse（secondsTextBox1.Text）; 
 =分钟totalSeconds / 60; 
 minutesRemainder = totalSeconds％60; 
小时数=分钟/ 60; 
 hoursRemainderMinutes =分钟％60; 
 hoursRemainderSeconds = hoursRemainderMinutes％60; 
 
如果（totalSeconds&下; 60）
 {
 MessageBox.Show（totalSeconds.ToString（））; 
} 
 
如果其他人（totalSeconds< 3600）
 {
 
 MessageBox.Show（minutes.ToString（）+分钟+ minutesRemainder的ToString（）+秒）; 
} 
 
如果其他人（totalSeconds> 3600）
 {
 MessageBox.Show（hours.ToString（）+小时+ hoursRemainderMinutes.ToString（）+ 分，+ hoursRemainderSeconds.ToString（）+秒）; 
} 
 
} 
  

解决方案

尝试使用的模块的算术

  INT totalSeconds = 7565; 
 
 INT小时= totalSeconds / 3600; 
 INT分钟=（totalSeconds％3600）/ 60; 
 INT秒=（totalSeconds 60％）; 
  

...

 如果（时间大于0）
 MessageBox.Show（的String.Format（{0}小时{1}分钟，{2}秒，时，分，秒））; 
否则如果（分钟大于0）
 MessageBox.Show（的String.Format（{0}分钟，{1}秒，分，秒））; 
，否则
 MessageBox.Show（的String.Format（{0}秒秒））; 
  

Okay first off, I'm pretty sure I'm not expected to use TimeSpan for this assignment; rather a formula series which shows the seconds, minutes, and hours in a message box when the user enters the number of seconds in the text box.

Here's where I'm stuck. We're supposed to check our answers with the example: 7565 seconds is 2 hours, 6 minutes, and 5 seconds. However, my code ends up calculating it as 2 hours, 6 minutes, and 6 seconds. It also keeps that answer when the initial number is 7560 seconds. I'm so confused!! It's a conditional scenario, in which the message box shows only the seconds if the user enters under 60 seconds, only minutes + seconds if the user enters between 60 and 3600 seconds, and hours + minutes + seconds if over 3600 seconds is entered. Here is what I have so far, and I'd appreciate any insight as to why my calculation is off :)

Thanks for the answers! But the 7565 isn't a constant; the user can enter any amount of seconds but my professor used 7565 as an example to check if we're on the right track.

private void calculateButton1_Click(object sender, EventArgs e)
    {
        int totalSeconds, hours, minutes, minutesRemainder, hoursRemainderMinutes, hoursRemainderSeconds;
        totalSeconds = int.Parse(secondsTextBox1.Text);
        minutes = totalSeconds / 60;
        minutesRemainder = totalSeconds % 60;
        hours = minutes / 60;
        hoursRemainderMinutes = minutes % 60;
        hoursRemainderSeconds = hoursRemainderMinutes % 60;

        if (totalSeconds < 60)
        {
            MessageBox.Show(totalSeconds.ToString());
        }

        else if (totalSeconds < 3600)
        {

            MessageBox.Show(minutes.ToString() + " minutes, " + minutesRemainder.ToString() + " seconds");
        }

        else if (totalSeconds>3600)
        {
            MessageBox.Show(hours.ToString() + " hours, " + hoursRemainderMinutes.ToString() + " minutes, " + hoursRemainderSeconds.ToString() + " seconds");
        }

    }

解决方案

Try using modular arithmetics

int totalSeconds = 7565;

int hours = totalSeconds / 3600;
int minutes = (totalSeconds % 3600) / 60;
int seconds = (totalSeconds % 60);

...

if (hours > 0)
  MessageBox.Show(String.Format("{0} hours, {1} minutes, {2} seconds", hours, minutes, seconds));
else if (minutes > 0)
  MessageBox.Show(String.Format("{0} minutes, {1} seconds", minutes, seconds));
else
  MessageBox.Show(String.Format("{0} seconds", seconds));
