Is this a correct way of assigning commands to a transaction in ado.net?

Connection.Open()
Command.Transaction = Connection.BeginTransaction()
Try
 Command.CommandText = "DELETE FROM table1 WHERE ID = @id "
 Command.Parameters.Add("@id", sID)
 Command.ExecuteNonQuery()

 Command.CommandText = "INSERT INTO table2( blah) VALUES( @blah )"
 Command.Parameters.Add("@blah", 111).DbType = DbType.Int64
 Command.ExecuteNonQuery()

 Command.Transaction.Commit()

Catch ex As Exception
 Command.Transaction.Rollback()
 Throw New Exception( ex.Message, ex)
Finally
 Command.Parameters.Clear()
 Connection.Close()
 Connection.Dispose()
 Command.Dispose()
End Try

Or do i need to create two different command instances one for each DML string and then seperately assign them to the Transaction?

Thanks
