try

string str = "select usr_nm from user_details";
           OleDbCommand cmd = new OleDbCommand(str, con);
           OleDbDataAdapter da = new OleDbDataAdapter(cmd);
           DataTable dt = new DataTable();
           da.Fill(dt);
           if(dt.Rows.Count >=3)
           {
                Label1.Text = dt.Rows[0][0].ToString();
               Label2.Text = dt.Rows[1][0].ToString();
               Label3.Text = dt.Rows[2][0].ToString();
           }
