How to add a delay for a 2 or 3 seconds [closed]

Question

How can I add a delay to a program in C#?

Answer 1

You could use Thread.Sleep() function, e.g.

int milliseconds = 2000;
Thread.Sleep(milliseconds);

that stops the execution of the current thread for 2 seconds.

Anyway, that could not fit your needs... what exactly are you trying to accomplish ?

Answer 2

Use a timer with an interval set to 2–3 seconds.

You have three different options to choose from, depending on which type of application you're writing:

1. System.Timers.Timer
2. System.Windows.Forms.Timer
3. System.Threading.Timer

Don't use Thread.Sleep, as that will completely lock up the thread and prevent it from processing other messages. Assuming a single-threaded application (as most are), your entire application will stop responding, rather than just pausing as you probably intended.

Answer 3

For 2.3 seconds you should do:

System.Threading.Thread.Sleep(2300);

Answer 4

System.Threading.Thread.Sleep(
    (int)System.TimeSpan.FromSeconds(3).TotalMilliseconds);

Or with using statements:

Thread.Sleep((int)TimeSpan.FromSeconds(2).TotalMilliseconds);

I prefer this to 1000 * numSeconds (or simply 3000) because it makes it more obvious what is going on to someone who hasn't used Thread.Sleep before. It better documents your intent.
