I want to create a excel spreadsheet directly from a SSIS script task which is being pulled from a stored procedure. I'm able to create single sheet workbook with one stored procedure but I'd like to add another another sheet to the same workbook but from a different stored procedure.  I'm taking this from an example from techbrothersIT

using System;
using System.Data;
using Microsoft.SqlServer.Dts.Runtime;
using System.Windows.Forms;
using System.IO;
using System.Data.OleDb;
using System.Data.SqlClient;

	public partial class ScriptMain : Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase

        public void Main()
        {
            string datetime = DateTime.Now.ToString("yyyy_MM_dd_HHmmss");
            try
            {
                //Declare Variables
                string ExcelFileName = Dts.Variables["User::ExcelFileName"].Value.ToString();
                string FolderPath = Dts.Variables["User::FolderPath"].Value.ToString();
                string StoredProcedureName = Dts.Variables["User::StoredProcedureName"].Value.ToString();
                string StoredProcedureName2 = Dts.Variables["User::StoredProcedureName2"].Value.ToString();
                string SheetName = Dts.Variables["User::SheetName"].Value.ToString();
                string SheetName2 = Dts.Variables["User::SheetName2"].Value.ToString();

                ExcelFileName = ExcelFileName + "_" + datetime;

                // Assumes that connection is a valid SqlConnection object.
                string queryString =
                  "EXEC  " + StoredProcedureName;

                TableColumns = TableColumns.Remove(TableColumns.Length - 2);
