The following code adds the numbers from 1 to 100 and returns the sum. What I'm trying to do is run the calculations in a backgroundworker and return a value. The problem with this is that returnValue is returned before DoWork completes. How can I have it wait for my background worker to complete before returning a value? (I can't seem to put the return in my DoWork...)
double returnValue = 0;
var b = new BackgroundWorker();
b.DoWork += new DoWorkEventHandler(
delegate(object sender, DoWorkEventArgs e) {
for(int i=0;i<100;i++){
returnValue += (i+1);
}
}
);
b.RunWorkerAsync();
return returnValue;
Addendum: Would it be better to send a message pump on the same thread instead of running this on a background worker?
Also, this is just example code, my actual code takes more than a minute to complete.
