How to add a delay for a 2 or 3 seconds

Question

How can I add a delay to a program in C

User · Answer

For 2 3 seconds you should do   System Threading Thread Sleep 2300

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

You could use Thread Sleep   function  e g   int milliseconds   2000  Thread Sleep milliseconds     that completely stops the execution of the current thread for 2 seconds   Probably the most appropriate scenario for Thread Sleep is when you want to delay the operations in another thread  different from the main  e g      MAIN THREAD        --------------------------------------------------------- gt    UI  CONSOLE ETC                                                                                                                    OTHER THREAD            ----- ADD A DELAY  Thread Sleep  ------ gt    For other scenarios  e g  starting operations after some time etc   check Cody s answer

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    System Timers Timer System Windows Forms Timer System Threading Timer   Don t use Thread Sleep if your application need to process any inputs on that thread at the same time  WinForms  WPF   as Sleep 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 delaying an operation as you probably intended  Note that it may be fine to use Sleep in pure console application as there are no  events  to handle or on separate thread  also Task Delay is better option    In addition to timers and Sleep you can use Task Delay which is asynchronous version of Sleep that does not block thread from processing events  if used properly - don t turn it into infinite sleep with  Wait        public async void ClickHandler                  whatever you need to do before delay goes here                 await Task Delay 2000             whatever you need to do after delay       The same await Task Delay 2000  can be used in a Main method of a console application if you use C  7 1  Async main on MSDN blogs    Note  delaying operation with Sleep has benefit of avoiding race conditions that comes from potentially starting multiple operations with timers Delay  Unfortunately freezing UI-based application is not acceptable so you need to think about what will happen if you start multiple delays  i e  if it is triggered by a button click  - consider disabling such button  or canceling the timer task or making sure delayed operation can be done multiple times safely
