Question

I want to call the background worker synchronously. I want execution of the code to end when backgroundworker has completed its execution.
My code for BackgroundWorker is here :

{
    BackgroundWorker worker = new BackgroundWorker();
    worker.DoWork += DoWork;
    worker.RunWorkerCompleted += RunWorkerCompleted;
    ...
    worker.RunWorkerAsync();
    //wait for execution to end 
}

One way of doing it will be to check the status again n again until its execution is completed but is there any other good way of doing it ?

If you don’t want your code to execute asynchronously, don’t put it in a BackgroundWorker…

{ 
    DoWork();
} 

However, if there is some obscure reason why you absolutely need to have the code in the BackgroundWorker, you can use the following:

ManualResetEvent mre = new ManualResetEvent(false);
BackgroundWorker worker = new BackgroundWorker(); 
worker.DoWork += DoWork; 
worker.RunWorkerCompleted += (s, e) => 
                             {
                                 RunWorkerCompleted(s, e); 
                                 mre.Set();
                             };
// ... 
worker.RunWorkerAsync();
mre.WaitOne();
