C# Progress Bar: how to wrap its use around specific object method

I'm having a heck of a time trying to figure this out. Currently I have my code working properly without using a progress bar for a particular object method. How do I use the BackgroundWorker and ProgressBar to display the progress of a particular method in my code within the form it's a part of?

Simply...how do I use the section "// Your background task goes here" to represent the progress of the method to my users.

currently:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        Shown += new EventHandler(Form1_Shown);

        backgroundWorker1.WorkerReportsProgress = true;
        backgroundWorker1.DoWork += new DoWorkEventHandler(backgroundWorker1_DoWork);
        backgroundWorker1.ProgressChanged += new ProgressChangedEventHandler(backgroundWorker1_ProgressChanged);
    }

    void Form1_Shown(object sender, EventArgs e)
    {
        backgroundWorker1.RunWorkerAsync();
    }

    void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
    {
        // Your background task goes here
        for (int i = 0; i <= 100; i++)
        {
            // Report progress to 'UI' thread
            backgroundWorker1.ReportProgress(i);
            // Simulate long task
            System.Threading.Thread.Sleep(100);
        }
    }

    void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
    {
        progressBar1.Value = e.ProgressPercentage;
    }

}//END Form1 class
