Question

我们最近在课堂上报道了“如果陈述等......”，我遇到了这个问题。（为我可怜的英语道歉）

这就是问题：

创建一个应用程序，让用户输入秒数并按以下方式工作：
一分钟内有60秒。如果用户输入的秒数大于或等于60，程序应显示分钟数在那么多秒钟。
一小时有3,600秒。如果输入的秒数如果用户大于或等于3,600，程序应显示该数字这几秒钟的小时数。
一天有86,400秒。如果用户输入的秒数大于或等于86,400，程序应显示的数量那么多秒钟。

这是我的错误答案：

    private void button1_Click(object sender, EventArgs e)
    {       
            //Declaring Variables
            int totalSeconds;
            int hours;
            int minutes;
            int minutesRemainder;
            int hoursRemainderMinutes;
            int hoursRemainderSeconds;

            // Parsing and calculations

            totalSeconds = int.Parse(textBox1.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 >= 84600)
            {
                MessageBox.Show(hours.ToString() + " hours, " + hoursRemainderMinutes.ToString() + " minutes, " + hoursRemainderSeconds.ToString() + " seconds");


        }
    }
}

}

运行时，我的程序不会计算任何内容。我究竟做错了什么？

Answer 1

您应该使用TimeSpan.FromSeconds method。

它将为您提供TimeSpan结构实例，您可以访问：

TotalDays
TotalHours
TotalMinutes

性质。

修改

他们在评论中说，你想要在不使用任何库的情况下实现这一目标。那么方法（就你的目标而言）：

int totalSeconds = ....;/// int totalMinutes = totalSeconds / 60; int totalHours = totalMinutes / 60; int totalDays = totalHours / 24; if (totalDays > 0){ //show days } else if (totalHours > 0){ //show hours } else if (totalMinutes > 0){ //show minutes } else { //show seconds }

Answer 2

确定。假设您不想使用TimeSpan。你的代码非常接近工作。你的问题是你的最后一个“else if”语句应该用if语句反转：

if (totalSeconds >= 86400)
{
    Console.WriteLine(days.ToString() " days," + hours.ToString() + " hours, " + hoursRemainderMinutes.ToString() + " minutes, " + hoursRemainderSeconds.ToString() + " seconds");
}
else if (totalSeconds >= 3600)
{
    Console.WriteLine(hours.ToString() + " hours, " + hoursRemainderMinutes.ToString() + " minutes, " + hoursRemainderSeconds.ToString() + " seconds");
}
else if (totalSeconds >= 60)
{
    Console.WriteLine(minutes.ToString() + " minutes, " + minutesRemainder.ToString() + " seconds");
}
else 
{
    Console.WriteLine(totalSeconds.ToString());
}

这样就可以了。

Answer 3

以下是如何计算所有值并确定输出中需要哪些值

int seconds = totalSeconds % 60;
int totalMinutes = totalSeconds / 60;
int minutes = totalMinutes % 60;
int totalHours = totalMinutes / 60;
int hours = totalHours % 24;
int totalDays = totalHours / 24;

if (totalDays > 0)
{
    Console.Write(totalDays + " Days ");
}
if (totalHours > 0)
{
    Console.Write(hours + " Hours ");
}
if (totalMinutes > 0)
{
    Console.Write(minutes + " Minutes ");
}

Console.WriteLine(seconds + " Seconds");

或使用StringBuilder，以便您可以在MessageBox

中显示它

int seconds = totalSeconds % 60;
int totalMinutes = totalSeconds / 60;
int minutes = totalMinutes % 60;
int totalHours = totalMinutes / 60;
int hours = totalHours % 24;
int totalDays = totalHours / 24;
StringBuilder builder = new StringBuilder;

if (totalDays > 0)
{
    builder.Append(totalDays + " Days ");
}
if (totalHours > 0)
{
    builder.Append(hours + " Hours ");
}
if (totalMinutes > 0)
{
    builder.Append(minutes + " Minutes ");
}

builder.Append(seconds + " Seconds");
MessageBox.Show(builder.ToString());

Answer 4

TimeSpan是最简单的方法。

        int Input = 32453; //Amount of seconds 
        TimeSpan ts = new TimeSpan(0, 0, Input); //3 constructor arguments are (Hours, Minutes, Seconds)
        if (ts.Days > 0)
        {
            Console.WriteLine(ts.Days + " Day(s)");
        }
        else if (ts.Hours > 0)
        {
            Console.WriteLine(ts.Hours + " Hour(s)");
        }
        else if (ts.Minutes > 0)
        {
            Console.WriteLine(ts.Minutes + " Minute(s)");
        }
        else
        {
            Console.WriteLine(ts.Seconds + " Second(s)");
        }
        Console.Read();

将秒转换为分钟，小时和天
