推荐答案

看看

Have a look at DateTime.Parse Method[^]. You can use that for your input.

使用 DateTime.TryParse [ ^ ]以避免不必要的操作例外.

Use DateTime.TryParse[^] to avoid unnecessary exception.

这比拔牙还差！
花大量时间一些了解 DateTime [ ^ ]结构，以及用它.除了简单的字符串相等性之外，您不能在存储为字符串的日期上使用比较运算符，即使那样您也会得到错误的答案.

This is worse than pulling teeth!
Spend some a lot of time learning about the DateTime[^] structure, and use it. You cannot use comparison operators on dates stored as strings, apart from simple string equality, and even then you can get the wrong answer.
