Detailed C # console Countdown

People who used to chat with each other a few years ago wrote a countdown to the form to calculate off-hours and vacation time:)

It's just a mockery of my job-free, hahaha.

The countdown of the form is quite without technical content, mainly not cool enough to reflect the identity of our programmers.

Then what's cool? Must be the console!

The screen of the hacker crackling and rolling screen of the TV show how cool!

So, we studied how to time on the control table.

Baidu to the old MSDN post, all the answers are the use of threads. Then use the thread.

The main timing method is to use Thread.Sleep (1000); method to make the main thread stop for one second.

It then loops through the thread call pass method, thread thread = new Thread (delegate () {GetTime (dt);});

This method calculates the time difference and then outputs the times.

This will complete a bug (than the heart, the intention to create a bug), although the calculation of time, then output, is basically not much time,

But hundreds of times thousands of times will result in two times less than a second output time, but for the final result is not a major hindrance.

(after knowledge, no thread call method should also be possible, mainly thread.sleep (1000);)

Start ();            Thread.Sleep (1000);        } console.readline (); }//Output timing remaining time static void GetTime (DatetIME dt) {//Get start time DateTime Dtnow = Convert.todatetime (DateTime.Now);            TimeSpan ts = Dt-dtnow;            Console.foregroundcolor = Consolecolor.green;            Console.setcursorposition (8, 5);            Console.WriteLine (TS); if (TS.                TotalSeconds <= 1) {console.setcursorposition (0, 9);                Console.WriteLine ("Timing completed");            Isend = true; }        }    }}

Console.foregroundcolor = Consolecolor.green; Change the color of the output character to green.

Console.setcursorposition (8, 5); Is the statement that changes the position of the cursor, which represents the 8th character of the 5th line of the cursor, at which time the output is output here.

The result of the output is still the original detailed time format, but a little modification will be more beautiful, and here are some output statements about time.
