report progress backgroundworker from different class c#

Question

In my .NET C# project I have used a \"BackgroundWorker\" to call a method in a different class. The following is the source-code of my main form

public parti         


        

Answer 1

I've just had this same issue (my long running process is a database restore), and solved it in a similar way by raising an event in the other class, but then had my subscriber to that event just act as a wrapper to backgroundWorker1.ReportProgress().

private void DBRestoreProgressHandler(DataAccess da, DataAccess.DatabaseRestoreEventArgs e)
    {
        backgroundWorker1.ReportProgress(e.RestoreProgress);
    }

private void backgroundWorker1_ReportProgress(object sender, ProgressChangedEventArgs e)
    {
        someLabel.Text = e.ProgressPercentage.ToString();
    }

This saved having to use:

base.Invoke((Action)delegate

Which I think can then cause problems if the form closes unexpectedly?
