Append a table from the rows returned by a SQL Statement

A SQL statement returns rows and columns.  This works well.

I need to append a table from the returned rows.

Currently I am using SQLDataReader to read column values into a dataset.
Then I am parsing the dataset one row at a time and building an array.

Then I am parsing the array one row at a time and appending the values to a table.

What do I need to do to Append a table from the rows returned by a SQL Statement.
The appended table can be a table that has been cleared. Then all rows might be appended in a single statement instead of building and parsing a dataset.  

//SQL statement returns rows and columns.
  SqlCommand cmdShowGrid = new SqlCommand("usp_getExceptions", conStockSelect);
            cmdShowGrid.Connection = conStockSelect;
            cmdShowGrid.CommandType = System.Data.CommandType.StoredProcedure;
            cmdShowGrid.CommandTimeout = 1200;
            cmdShowGrid.CommandText = "usp_getExceptions";
            cmdShowGrid.Parameters.Clear();
            // cmdShowGrid.Parameters.AddWithValue("@MarketID", SqlDbType.Int).Value = 2;
            cmdShowGrid.Parameters.AddWithValue("@CurrFromDate", SqlDbType.Date).Value = dteSampleBCStart;
            cmdShowGrid.Parameters.AddWithValue("@CurrToDate", SqlDbType.Date).Value = dteSampleABStart;
            cmdShowGrid.Parameters.AddWithValue("@PrevFromDate", SqlDbType.Date).Value = dteSampleABEnd;
            cmdShowGrid.Parameters.AddWithValue("@PrevToDate", SqlDbType.Date).Value = dteSampleBCEnd;
            cmdShowGrid.Parameters.AddWithValue("@Min5DayAvg", SqlDbType.Decimal).Value = 1.00;
            cmdShowGrid.Parameters.AddWithValue("@Max5DayAvg", SqlDbType.Decimal).Value = 100.00;
            cmdShowGrid.Parameters.AddWithValue("@Curr5Prev8Min", SqlDbType.Decimal).Value = 1.05;
            cmdShowGrid.Parameters.AddWithValue("@Curr5Prev8Max", SqlDbType.Decimal).Value = lstMaxCurr5Prev8.SelectedValue; //Decimal.Add(decIncreases, decIncreasesPlus);
 
//using SQLDataReader to read column values into a dataset.
          SqlDataAdapter adpExceptions = new SqlDataAdapter(cmdShowGrid);
            DataSet dstExceptions = new DataSet();
            adpExceptions.Fill(dstExceptions, "Exceptions");

            SqlDataReader rdrStockHist;

            rdrStockHist = cmdShowGrid.ExecuteReader();

            double[,] dblArrException = new double[2000, 8];  // Numerical parameter values
            string[,] strArrException = new string[2000, 2];  // String parameter values

//Parsing the dataset one row at a time and building an array.
          if (rdrStockHist.HasRows)   // Build the array
            {
                while (rdrStockHist.Read())
                {
                    // Read the col values into arrays
                    dblArrException[intRow, 0] = Convert.ToDouble(rdrStockHist["SymbolID"]);
                    dblArrException[intRow, 1] = Convert.ToDouble(rdrStockHist["Curr5DayAvg"]);
                    dblArrException[intRow, 2] = Convert.ToDouble(rdrStockHist["Prev8DayAvg"]);
                    //dblArrException[intRow, 3] = Convert.ToDouble(rdrStockHist["PctChg"]);
                    //dblArrException[intRow,4]  = Convert.ToDouble(rdrStockHist["MarketID"]);
                    //dblArrException[intRow, 5] = 0;  Convert.ToDouble(rdrStockHist["PctUp"]);

                    //strArrException[intRow,0]  = rdrStockHist["SymbolName"].ToString();
                    //strArrException[intRow,1]  = rdrStockHist["SiteURL"].ToString();

                    intRow++;
                }
            }  // End (rdrSymbols.Read())

            rdrStockHist.Close(); // closing SqlDataReader
