            if (openfiledialog1.ShowDialog() == DialogResult.OK)
            {

                string connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + openfiledialog1.FileName;
                const string connectionStringDest = @"server=ahmad-pc\anfd;database = phonebook;Integrated Security = true";
                using (var sourceConnection = new OleDbConnection(connectionString))
                {
                    sourceConnection.Open();

                    var commandSourceData = new OleDbCommand("SELECT * from numberperson", sourceConnection);
                    var reader = commandSourceData.ExecuteReader();

                    using (var destinationConnection = new SqlConnection(connectionStringDest))
                    {
                        destinationConnection.Open();

                        using (var bulkCopy = new SqlBulkCopy(destinationConnection))
                        {


                            bulkCopy.ColumnMappings.Add("name", "nameperson"); //THIS A MAPPING REPLACE IT WITH YOUR NEED

                                Console.WriteLine(ex.Message);
                            }
                            finally
                            {
                                reader.Close();

            }

Answer 1

SQLBulkCopy only does Bulk inserts so any existing data should not be modified.

For MS Access > 2003 you'll need to use Microsoft ACE instead of JET
