问题描述

int Month = DateTime.Now.Month - 1;

for (int i = Month; i <= 11; i++)
{
   Month++;
   using (DataTableAdapters.AttendanceRegisterTableAdapter Reg = new RRHFOEM04.DataTableAdapters.AttendanceRegisterTableAdapter())
   {
      Reg.AttendanceRegister_Insert(txtStudentID.Text, Convert.ToString(DateTime.Now.Hour + ":" + DateTime.Now.Minute), Convert.ToString(Month), "2014", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "");

以上代码仅插入当前年份...但我想插入下一个从当月起24个月

Above code are insert only current year month... but i want to insert next 24 month from current month

推荐答案

尝试：

Try:

DateTime now = DateTime.Now;
int Month = now.Month - 1;
DateTime twoYearsAhead = now.AddMonths(24);
...

然后保存该值。



（最好只在需要时读取当前时间一次它会导致间歇性的奇怪错误，如果日期或时间在提取之间发生变化则非常难以追踪，例如在每分钟结束时发生。

Then save that value.

(It's a good idea to only read the current time once when you need it, or it can cause intermittent odd errors which are very difficult to track down if the date or time changes between fetches, as happens at the end of each minute for example.
