C# countdown timer

Question

I\'m trying to make a countdown using C# and show the time in format:

hour:minutes:seconds

I\'ve tried this:

 var minutes          


        

Answer 1

Your code sets up the variables then goes to sleep for 3 minutes so the if-statement isn't executed until it leaves the sleep state. Either set up a new thread to update the UI or do something like this...

while (DateTime.now < end) {
  label1.Text = "...";
  Thread.Sleep(#); //Pick a second, or 5 or whatever
}

label1.Text = "Done!";

With a 2nd thread you can still do stuff in your program while it works. "Done!" will appear once it finishes.
