Background worker - report progress with string array

Question

I need to return multiple STRING values from my backgroundworker in each loop, so I tried to use ReportProgress second parameter as string array. Example of code:

I've solved a similar issue by adding a new ProgressChanged event listener to your background worker and block passing to the next loop if ProgressChanged not fired:

bool progressed;

backgroundWorker1.ProgressChanged += new ProgressChangedEventHandler(bw_ProgressChanged);
string[] workerResult = new string[2];
for (int i = 0; i < 2; ++i) {
    progressed=true;

    workerResult[0] = "this string";
    workerResult[1] = "some other string";
    backgroundWorker1.ReportProgress(i, workerResult);
    while (progressed)
    {
       //you can add a thread sleep 
    }
}


void bw_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
     progressed = false;
}
