How can I paste selected data into another Excel sheet using OLEDB?

I have 2 Excel sheets. My requirement is, I have to copy all the data from one Excel sheet to another. Below is code snippet for the same, below code is copying and pasting all the data from one sheet to another in Excel, but its not pasting the data from A1 range.

I want the selected data to be pasted in another Excel sheet starting from 1st row. Also, I want to delete and insert fresh data every time the button is clicked, instead of appending into the same. Please help.

                        adapterdest.InsertCommand = insertCommand;


                        if (connectiondest.State == ConnectionState.Closed)
                        {
                            connectiondest.Open();
                        }
                        if (Job.Tables.Count > 0 && Job.Tables[0].Rows.Count > 0)
                        {

                                insertCommand.CommandText = "Insert into [Job_updated$] values ('" + JobCode + "', '" + JobName + "', '" + StartDate + "', '" + EndDate + "') ";
                                //insertCommand.CommandText = "UPDATE [Job_updated$E1:E1] SET F1='MyNewCol';";
                                insertCommand.ExecuteNonQuery();
                            insertCommand.Dispose();
                        }
                        connectiondest.Close();
                        dataGridView1.DataSource = Job.Tables[0]开发者_开发技巧.DefaultView;
                    }
                }

            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }

        }

    }
}

but its not pasting the data from A1 range because first row is considered to be the headers for the table (sheet) either create them manually or use getRange to do that.

// Create an array for the headers and add it to cells A1:C1.
object[] objHeaders = {"Order ID", "Amount", "Tax"};
m_objRange = m_objSheet.get_Range("A1", "C1");
m_objRange.Value = objHeaders;

in order to insert new data each time perform a delete command before inserting oleDb does not sopport the delete command

Excel.Range ran = (Excel.Range)sheet.Rows[5, Type.Missing];
ran.Select();
ran.Delete(Excel.XlDirection.xlUp);
