Datetime Q

[Techno]

Just a quickie

I am trying to see how long it takes to do something

the way I am checking to see if the time elapsed is less then a second is this, but it never seems to exit the loop:

while (DateTime.Now.Millisecond < 1000)
{
   this.lstMsgs.Items.Add(DateTime.Now.Millisecond.ToString());
}
this.lstMsgs.Items.Add("1 sec up");

it never seems to exit the loop.

any ideas?

umm you're not understanding this correctly
DateTime.Now returns the current time, so you're basically saying while the current time's milliseconds is less than 1000 repeat the loop.
I would just use the system tickcount (the value is in milliseconds... usually means the number of milliseconds since the system was rebooted)

int startTick = Environment.TickCount;
do
{
//stuff here
}while (Environment.TickCount - startTick <1000)


you could also use a TimeSpan object, or try using DateTime's Subtract() method, but I think what I just said above is fairly efficient.

oh yeh, of course ...
