You have an SQL query that takes one minute to execute. You use the following code segment to execute the SQL query asynchronously. IAsyncResult ar = cmd.BeginExecuteReader( ); You need to execute a method named DoWork( ) that takes one second to run while the SQL query is executing.DoWork( ) must run as many times as possible while the SQL query is executing. Which code segment should you use?()

The music sounded(). I enjoyed every minute of it.
SMED(single minute exchange of die,单分钟快速换模)是精益生产的重要技术,要区分内部换型调整作业和外部换型调整作业。为了缩短换型调整时间,操作人员必须在设备运行时完成所有的“外部换型调整作业”,一旦设备停止下来则应集中全力于“内部换型调整作业”。并尽可能的把“内部换型调整作业”转变为“外部换型调整作业”,缩短这两种作业的时间,以保证迅速完成完成换型调整作业。以下可配合用于SMED的方法有:()
有一个Time类,包含数据成员minute(分)和sec(秒),模拟秒表,每次走一秒,满60秒进一分钟,此时秒又从0开始算。要求输出分和秒的值。初值自拟。
