Pull it out on a report. But how?

Hi!

With this code below I can find one record on my "last_name" column. But there is a think I would like to learn that until now I didnt. I want to pull out this data I on a report builder.

I already have the bascis to create and save a report from report builder. Then I want to know how to generate from these codes?

private void btnFind_Click(object sender, EventArgs e)
string searchFor = textBox5.Text;

            int results = 0;
            DataRow[] returnedRows;

            returnedRows = ds1.Tables["Workers"].Select("last_name='" + searchFor + "'");            
            results = returnedRows.Length;

            if (results > 0)
            {
                DataRow dr1;
                dr1 = returnedRows[0];

                MessageBox.Show(dr1[1].ToString() + " " + dr1[2].ToString());
            }
            else
            {
                MessageBox.Show("No such Record");
            }
        }
    }
}
