如何找到第三个星期五在一个月C＃？
有这么一个特定的事件只会发生在一个条件的第一个和第三 *的周三的*每月。我试图做到这一点像下面，
There's a condition that a specific event will occur only on first and third *Wednesday* of every month. I am trying to achieve this like below,
DateTime nextMeeting = DateTime.Today.AddDays(14);
int daysUntilWed = ((int)DayOfWeek.Wednesday - (int)nextMeeting.DayOfWeek + 7) % 7;
DateTime nextWednesday = nextMeeting.AddDays(daysUntilWed);
但我没有得到期望的结果。我肯定，我错过了一个逻辑或有ASP.NET中的任何方法，通过它我能做到这一点？
详细资料：我想通过点击一个按钮，将设置标签，以显示下周三（以先到为准）
But I am not getting the desired result. I am sure, I am missing out on a logic or is there any method in ASP.NET through which I can do that? More Detail: I am trying to display the next Wednesday (whichever is first) by clicking on a button which will set the label.
答
试试这个：
var FirstDay = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1);
//first wednesday
while (FirstDat.DayOfWeek != DayOfWeek.Wednesday)
FirstDay = FirstDate.AddDays(1);
//3rd wednesday
var ThirdWed = FirstDay.AddDays(14);
