检查日期时间变量的时间间隔 [英] check Time interval for datetime variable

问题描述

我正在asp.net中开发网站以进行在线预订.在我的网站中，我花费时间进行预订.假设如果有一个选择时间，则其他用户不能在该其他用户时间的30分钟之前或之前预订，这意味着如果我在3:30时预订，则其他用户不能预订该时间，如果他们想预订，则只能选择3:00或4:00时间.

I am developing website in asp.net for online booking.In my website i use time for booking. Suppose if any one select time then other user can not book after or before 30min of that other user time means if i book at 3:30 then other user can not book this time and if they want to book they only select 3:00 or 4:00 time.
Can any one help me to solve this.
