公历（阳历）和农历（阴历）相互转换，公历转农历代码是从网上当的，我做了农历转公历的代码并写了示例程序。其实网上也有很多有关公历转农历的控件，但作为一个程序员就是不太习惯于使用别人的控件，因为那样将不便调试和差错。-calendar (Gregorian calendar) and the Chinese (lunar calendar) 2008, the Lunar calendar code is transferred from the Internet when, I did a Lunar calendar to write the code and the sample program. In fact, the Internet has many of the Lunar calendar to the controls, But as a programmer is not accustomed to the use of other people's control, as that would inconvenience debugging and error.
