本文所述是一个小巧且功能简单的C#闹钟程序代码AlarmClock，程序涉及到了AxInterop.MSMask.dll与Interop.MSMask.dll两个控件，对编写时间闹钟或许有点参考价值。
完整实例代码如下：
using System; using System.Drawing; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data; namespace AlarmClock { /// <summary> /// Form1 的摘要说明。 /// </summary> public class Form1 : System.Windows.Forms.Form { private System.Windows.Forms.MonthCalendar monthCalendar1;

} } base.Dispose( disposing ); } #region Windows 窗体设计器生成的代码 /// <summary> /// 设计器支持所需的方法 - 不要使用代码编辑器修改 /// 此方法的内容。 /// </summary> private void InitializeComponent() { this.components = new System.ComponentModel.Container();
