How to play a sound with the count down

Question

2.50/5 (2 votes)

See more:

I have a windows form application that allows me to see count down. I would like to play a warning sound in a specific time. For example at 11:06 am.

C#

var curTime = DateTime.Now.TimeOfDay;
var soundTime= new TimeSpan(11, 06, 0);

......

 if(curTime==soundTime)
{
   SoundPlayer simpleSound = new SoundPlayer(@"c:\Windows\Media\Windows Logon Sound.wav");
   simpleSound.Play();
}

Basically when the count down clock reaches the specific time, I wanted to play that sound file however it doesn't work.

"Doesn't work" ... doesn't go into your code at all or it does get there but the sound doesn't play?

It does get there however the sound file doesn't play. I create a separate file for testing the sound file and it worked. However when the time is arrived, it doesn't play the sound.

It is probably because curTime will also have milliseconds, so your test if(curTime==soundTime) would be unlikely to be true (Chances of hitting the exact 0 milliseconds is slim!). Try if(curTime>=soundTime) instead (and remember to reset the timer or loop or whatever you are using to count down)

That works. I should have thought before I post. Thank you!

This works for me

C#

var soundTime= new TimeSpan(11, 06, 0);
DateTime start = new DateTime(2009, 12, 9, 10, 0, 0); //10 o'clock
DateTime end = new DateTime(2015, 12, 10, 12, 0, 0); //12 o'clock
DateTime curTime = DateTime.Now;
if ((curTime > start) && (curTime < end))

 
 //if(curTime==soundTime)
            {
                System.Media.SoundPlayer player = new System.Media.SoundPlayer(@"c:\Windows\Media\Windows Logon Sound.wav");
                player.Play();
            }

I am assuming than your code is running in a timer (actually I am sure)

C#

var soundTime = new TimeSpan(11, 06, 0);

var curDate = DateTime.Now;
if (soundTime.Equals(new TimeSpan(curDate.Hour, curDate.Minute, curDate.Second)))
{
   SoundPlayer simpleSound = new SoundPlayer(@"c:\Windows\Media\Windows Logon Sound.wav");
   simpleSound.Play();
}

If your code block is in timer tick event, if(curTime >= soundTime) will fire continuously and will fail.

See my (quoted) comment "and remember to reset the timer or loop or whatever you are using to count down". I actually used my test code in a Timer tick event and it worked ok - as long as I stopped the timer or changed the soundTime (to past or far future) [Edit - "past" d'oh. I didn't try that - for obvious reasons!]

Right, I did not see your comment :)

That's ok ... I'm clearly not seeing straight myself at the moment :-)

OP has confirmed that my suggestion in a comment works

So the OPs code becomes

C#

var curTime = DateTime.Now.TimeOfDay;
var soundTime= new TimeSpan(11, 06, 0);


......

 if(curTime >= soundTime)
            {
                SoundPlayer simpleSound = new SoundPlayer(@"c:\Windows\Media\Windows Logon Sound.wav");
                simpleSound.Play();
            }
