Question

I couldn’t find a solution for this yet…hope someone can help me.

I have a backgroundworker that runs until it is cancelled by the user (it reads data from a socket and writes it into a file).

Now I want to split the output file after a certain period of time, e.g. every 2 mins create a new file.

For this to happen I’d like to use a timer, something like

private void bckWrkSocket_DoWork(object sender, DoWorkEventArgs e)
{
//create timer and set its interval to e.Argument
//start timer

while(true)
{
    if(timer.finished == true)
    {
    //close old file and create new
    //restart timer
    }
 ...
}
}

Any suggestions / ideas?

edit: Stopwatch did the trick. Here’s my solution
Here’s my solution:

private void bckWrkSocket_DoWork(object sender, DoWorkEventArgs e)
{
long targettime = (long) e.Argument;
Stopwatch watch = new Stopwatch();
if (targettime > 0)
            watch.Start();
while(true)
{
    if ((targettime > 0) && (watch.ElapsedMilliseconds >= targettime))
    {
    ...
    watch.Reset();
    watch.Start();
    }
}

Use a Stopwatch and check within the while loop the Elapsed property. That way you prevent from concurrent writing and closing the same file.
