passing the result of a stored procedure to a datatable

I am running  a stored procedure and will like to pass the result to a datatable. How can I achieve this please. The code below here  is giving me errors.

Thanks.


private DataTable GetSelectCare()
        {
            DataTable dtselectCare = null;
            try
            {
                dtselectCare = new DataTable();
                occom.CommandText = "DispSelectCare";
                occom.CommandType = CommandType.StoredProcedure;
                dtselectCare = occom.ExecuteNonQuery();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);

            }
            return dtselectCare;
        }
