c# - Check connection time out, preferable check using long elapsedTicks or DateTime elapsedTime? -

tcp server send data buffer , mainform receive data buffer , processing

i have parameter check time on lastdatareceive (from tcp) on buffer.

i have paramter check time on datareceivenow (from buffer) on mainform.

now, want calculate elasped time, if lastdatareceive (from tcp) - datareceivenow (from buffer) > 60 seconds, prompt messagebox.show(" connection time out ");

i have 2 method on doing it, don't know 1 gives best result or both same?

1st method: elasped time using datetime format , check condition of 1 second

private void checkconnectiontimeout() {     if (datetime.now.subtract(receiver.lastdatareceivedtime).totalseconds > 60)     {         messagebox.show("connection out");     }     else     {         // ever     } } 

2nd method: elasped time calculating elapsedticks

private void checkconnectiontimeout() {     long datatimeout = (long)timespan.fromticks(receiver.lastdatatick - datareceiveticknow).totalseconds;      datetime dt = new datetime(datatimeout);      if (dt.second > 60)     {         messagebox.show("connection out");     }     else     {           // ever                } } 

neither of recommended, , can dangerous.

instead, use stopwatch class measure elapsed duration. reference documentation here.
