推荐答案

你究竟如何验证这一点真的取决于你：我们没有想法如何存储信息，或者需要在何处，甚至何时验证。



但是......解决这个问题非常简单：

假设您今天正在使用：

Exactly how you will validate this is really down to you: we have no idea how you are storing the info, or what needs verifying where, or even when.

But... working it out is pretty easy:
Assume you are working with today:

Dim today As DateTime = DateTime.Now.[Date]
Dim start As New DateTime(today.Year, today.Month, 1)
Dim [end] As DateTime = start.AddMonths(1).AddDays(-1)
Dim renew As DateTime = [end].AddYears(1)

你尝试了什么？你被困在哪里？你的代码在哪里？

What did you try? Where are you stuck? Where is your code?
