try {

catch (SQLException ex) {
    // Basically, without saying too much, you're screwed. Royally and totally.

我一直很喜欢Paul DiLascia在他的文件头中写的:

// If this code works, it was written by Paul DiLascia. If not, I don't know
// who wrote it

DataRow[] foundrows = FilterCalendarEntriesBecauseDotNETIsFuckedUp(tbtemp,CalDate);

不是注释，而是一个有趣的函数名
