What is the best way to implement C#'s BackgroundWorker in Delphi?

Question

I use C#'s BackgroundWorker object frequently to start a thread and perform a task. What's the easiest way to accomplish the same thing in Delphi?

Here's some code in C#:

private void button1_Click(object sender, EventArgs e)
{
  BackgroundWorker bg = new BackgroundWorker();
  bg.DoWork += new DoWorkEventHandler(bg_DoWork);
  bg.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bg_RunWorkerCompleted);
  test_number++;
  object[] arguments = { "test", test_number };
  bg.RunWorkerAsync(arguments);
}

void bg_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
      // done.
}

void bg_DoWork(object sender, DoWorkEventArgs e)
{
     // do actual work here
}

Answer 1

Look into OmniThreadLibrary by Primoz Gabrijelcic, or into AsyncCalls by Andreas Hausladen, which should both give you similar functionality.

Answer 2

for your solution this is: delphi-components/backgroundworker this component like c# backgroundworker's event, property etc.
