DataTime.Now.Ticks 的值表示自 0001 年 1 月 1 日午夜 12:00:00 以来所经历的以 100 纳秒为间隔的间隔数，可用于较精确的计时。
 
 
 
1秒=1000豪秒 1毫秒=1000微秒 1微秒=1000毫微秒（纳秒）
 
 
 
例如，需要在网页上显示该页面的运行时间，则只需在在页面加载时记录该值，在页面结束时再使用此值与先前的值相减，即得出页面的运行时间。如：

比如 SQL 语句：
 
Update [table] Set [CreateDate]=@CreateDate Where ...
 
其参数使用：New OleDbParameter("@CreateDate", Now)
 
当执行 SQL 语句向 Access 数据库中更新时会报错。而相同的语句使用 SQLParameter 向 SQLServer 中更新时没问题。
 
换一种方法，改为：

今天写了个小程序，用于将数据库内容导出到文本文件中，各字段之间用制表符分隔。
 
导出后用 Excel 打开时提示错误“SYLK： 文件格式无效”，确定后依然能正常打开，不知是何原因。
 
到 MSDN 查找后才知道，所谓 SYLK 文件也是文本文件，不过文件的前两个字符是大写的字母“ID”，正好我所导出的文件前两个字符正是大写的“ID”，所以会出现此提示。之所以还能正常打开，是 Excel 试图转换失败后又将其按普通文本文件再打开。
