C# does not have "click events". What context is your code running in? – Uwe Keim Feb 19 '18 at 16:08

At first i checked Thread.Sleep method but many people say it is not good cause it makes the whole programm crash for 3 seconds and you cant do anything else. Then i checked Windows.Forms.Timers but i cant fifure out a way to do the thing i want – Marios P Feb 19 '18 at 16:09

Use `await Task.Delay`. – SLaks Feb 19 '18 at 16:11

Thread.Sleep will hang the UI if you are mistakenly doing all your calculations on it.. – BugFinder Feb 19 '18 at 16:11

This won't freeze your UI:
async void button1_Click(object sender, EventArgs e)
{
await Task.Delay(TimeSpan.FromSeconds(3));
do something;
}

You can pause your current thread using Thread.Sleep :
using System.Threading;
TimeSpan interval = new TimeSpan(0, 0, 0, 3); // 3 seconds
Thread.Sleep(interval);

True, doing that on the UI Thread would cause the UI to freeze for 3 seconds. – Georg Patscheider Feb 19 '18 at 16:12

I would use the Thread.Sleep() function. Parameter is given in miliseconds ´
private void button1_Click(object sender, EventArgs e)
{
System.Threading.Thread.Sleep(5000);
//following code
}
If you don't want to freeze the UI. You can use this stackoverflow answer
