Is there a way to specify the minimum and maximum value of progressbar while using it through backgroundprocess?

C#

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
     {

         int[] arr = new int[21];
         for (int i = 1; i <= 20; i++)
         {
             arr[i] = i;
             Thread.Sleep(100);
             int m = (int)((1* 100)/arr.Length);
             backgroundWorker1.ReportProgress(i*m);
         }
     }

I'm using the above code and it does not do the job.. The progress bar never reaches 100% as I'm just typecasting. I want to set the maximum value of progress bar to (arr.length) so that there's no need to typecast. Please help.

I have seen this.. Is it enough if I mention
<pre>progressbar1.Maximum = arr.Length;</pre>
in the backgroundprocess1_DoWork()?

Why are dealing that way with the array indices? I would have writeen it this way:

C#

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
     {
         int[] arr = new int[20];
         double d = 100.0 / arr.Length;
         for (int i = 0; i < arr.Length; i++)
         {
             arr[i] = (i+1);
             Thread.Sleep(100);
             int p = (int) Math.Round((i+1)* d);
             backgroundWorker1.ReportProgress(p);
         }
     }
