I have a SSIS package in which I've added a Script Task. In the Script Task I've given a oledb connection manager and acquired a data table from the database and the query is just working fine. Now I have to put the data table into an excel file. This is the primary solution I need to arrive at.
There are two scenarios though

Scenario 1 : Creating an excel file template WITHOUT HEADERS and put the data into that excel file (DataTable has headers too) including DataTable's headers

Scenario 2 : Dynamically creating an excel file and put the data into it (I'm searching an answer for this scenario for a long time).

Please guide me through to find a solution :)

Below is my code which I've implemented in my Script Task :

public void Main()
        {
            DataTable DtUsers = new DataTable();           
            ConnectionManager ConnManager;
            OleDbConnection ConnOledb;
            OleDbDataReader dataReader;
            string SqlString = "MYQUERY";
            try
            {
                Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSConnectionManagerDatabaseParameters100 ConnParams;
                ConnManager = Dts.Connections["OledbConnectionUnit"];
                ConnParams = (Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSConnectionManagerDatabaseParameters100)ConnManager.InnerObject;
                ConnOledb = (OleDbConnection)ConnParams.GetConnectionForSchema();
                OleDbCommand CommOledb = new OleDbCommand();
                OleDbDataAdapter DaUsers = new OleDbDataAdapter();                
                try
                {
                    CommOledb.CommandText = SqlString.ToString();
                    CommOledb.CommandType = CommandType.Text;
                    CommOledb.Connection = ConnOledb;
                    dataReader=CommOledb.ExecuteReader();
                    DtUsers.Load(dataReader);
                    foreach (DataRow DrRows in DtUsers.Rows)
                    {
                        DrRows["Column_Name"].ToString();
                    }              
                }
                catch (Exception ex)
                {
                    throw ex;
                }
                Dts.TaskResult = (int)ScriptResults.Success;
            }
            catch(Exception ex)
            {
                throw ex;
            }
        }
        
        
    }



Thanks in advance

Hurrrrraaaaaaayyyyyyyyyy!!!!!!!!!!!!

I solved it myself . I created excel file dynamically :D I've used VB to do it. I got the solution. I've created headers toooooooooo :D . Everything is getting created dynamically.

Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Runtime

    Enum ScriptResults
        Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success
        Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
    End Enum

    Public Sub Main()

        Dim ConnOledb As OleDb.OleDbConnection

        cmConnMgr = Dts.Connections("OLEDBConn")
        cmParams = CType(cmConnMgr.InnerObject, Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSConnectionManagerDatabaseParameters100)
        ConnOledb = CType(cmParams.GetConnectionForSchema(), OleDb.OleDbConnection)




        Dim strSQL As System.Text.StringBuilder = New System.Text.StringBuilder
        Dim drReader As OleDb.OleDbDataReader
        Dim cmdCommand As New OleDb.OleDbCommand
        Dim dtDetails As New System.Data.DataTable

        strSQL.Append("SELECT first_name,email FROM xxxx where user_id <=2000")

        Try
            cmdCommand.CommandText = strSQL.ToString
            cmdCommand.CommandType = CommandType.Text
            cmdCommand.Connection = ConnOledb

            drReader = Nothing
            drReader = cmdCommand.ExecuteReader()
            If drReader.HasRows Then
                dtDetails.Load(drReader)
            End If
            drReader.Close()

        Catch ex As Exception
            drReader = Nothing
        End Try

        MsgBox(dtDetails.Columns.Count)
        MsgBox(dtDetails.Rows.Count)



        Dim excel As New Microsoft.Office.Interop.Excel.ApplicationClass()
        Dim Format As XlFileFormat = XlFileFormat.xlExcel8

        With excel
            .SheetsInNewWorkbook = 1
            .Workbooks.Add()
            .Worksheets(1).Select()

            'Create Column Header
            Dim i As Integer = 1
            For col = 0 To dtDetails.Columns.Count() - 1
                .Cells(1, i).value = dtDetails.Columns(col).ColumnName.ToString
                .Cells(1, i).EntireRow.Font.Bold = True

                i += 1
            Next
            i = 2


            Dim k As Integer = 1

                For row = 0 To dtDetails.Rows.Count() - 1
                    .Cells(i, k).Value = dtDetails.Rows(row).Item(col).ToString
                    i += 1
                Next

                k += 1

            Next

            .ActiveCell.Worksheet.SaveAs("C:\testing.xls", Format)
            .Workbooks.Close()

        End With

        excel.Quit()
        System.Runtime.InteropServices.Marshal.ReleaseComObject(excel)
        excel = Nothing

        Dts.TaskResult = ScriptResults.Success
