本文主要是介绍系统小闹钟V1.0 C#程序小例，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
因为发现自己经常计划好了做些什么事儿，到点儿了有时候经常忘，于是自己用C#写了一个系统闹钟程序。
目前是V1.0版本 后期还会继续优化。。
程序实例可在本网资源中下载http://download.csdn.net/detail/tskyfree/4239406
软件名称：Clock v1.0
软件功能：设定闹钟
具体详解：
左侧显示系统当前日期
显示系统当前时间：图形化表盘+数字化显示
区间模式：
设定任务名称
设定任务起止时间
显示当前任务状态
填写合理时间并设定，任务中可随时终止或退出程序
计时模式：
设定任务名称
设定距任务执行的倒计时时间
显示当前任务状态
填写合理时间并设定，任务中可随时终止或退出程序
窗体最小化后不显示在任务栏中，在右下侧托盘区显示小图标，点击小图标可还原 窗体
任务计时到达终止条件时：自动弹出提示，窗体置顶
支持快捷键操作 Alt+相应快捷键
