Timer Example

This post is for C# Timer.

Red box is my added item.

I added 2-buttons, 2-texts and 1 timer.

Start timer as click to button '시작'.

Finish timer as click to button '종료'.

First, make global variable 'timerCount'.

1	int timerCount = 0;

And button listener.

1 2 3 4 5 6 7 8 9 10

private void button1_Click(object sender, EventArgs e) { timer1.Start(); } private void button2_Click(object sender, EventArgs e) { timer1.Stop(); timerCount = 0; timerText.Text = "00:00:00"; }

Line 1~4 : button '시작' 

Line 6~11 : button '종료'

Start timer as click button '시작'

Finish timer ans initialize variable as click button '종료'

Below code is timer tick.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

private void timer_display(object sender, EventArgs e) { timerCount++; int sec = 0, min = 0, hour = 0; if (timerCount < 60) { sec = timerCount; } else if (timerCount < 3600) { min = timerCount / 60; sec = timerCount % 60; } else { hour = timerCount / 3600; min = (timerCount % 3600) / 60; sec = ((timerCount % 3600) % 60); } timerText.Text = hour.ToString("00")+":"+min.ToString("00")+":"+sec.ToString("00"); }

This code is increase variable and display text and calculate.

Line 20 : ToString() is  to string transfer method. 

Timer set using property window.

You just change Interval.

unit is millisecond. 

Icon spark is set for callback function.

Run~

Click to button '시작'.

Run to timer and display timer text.
