First create TimeSpan and then format it to whatever format you want:
首先创建 TimeSpan，然后将其格式化为您想要的任何格式：
TimeSpan span = TimeSpan.FromMinutes(minutes);
string label = span.ToString(@"hh\:mm\:ss");

Create a new TimeSpan:
创建一个新的TimeSpan：
var pauseDuration = TimeSpan.FromMinutes(minutes);
You now have the convenient properties Hours, Minutes, and Seconds. I should think that they are self-explanatory.
您现在有方便的特性Hours，Minutes和Seconds。我应该认为它们是不言自明的。

This is something that should give you someplace to start. The Timer is set for 1000ms. It is using the same ideas as the other answers but fleshed out a bit more.
这应该给你一个开始的地方。定时器设置为 1000 毫秒。它使用与其他答案相同的想法，但更加充实。
public partial class Form1 : Form
{
TimeSpan duration;
public Form1()
{
InitializeComponent();
}
private void timer1_Tick(object sender, EventArgs e)
{
duration = duration.Subtract(TimeSpan.FromSeconds(1)); //Subtract a second and reassign
if (duration.Seconds < 0)
{
timer1.Stop();
return;
}
lblHours.Text = duration.Hours.ToString();
lblMinutes.Text = duration.Minutes.ToString();
lblSeconds.Text = duration.Seconds.ToString();
}
private void button1_Click(object sender, EventArgs e)
{
if(!(string.IsNullOrEmpty(textBox1.Text)))
{
int minutes;
bool result = int.TryParse(textBox1.Text, out minutes);
if (result)
{
duration = TimeSpan.FromMinutes(minutes);
timer1.Start();
}
}
}
}
