如何验证日期? [英] How to validate dates?

问题描述

大家好，我在验证两个日期在一起时遇到问题，它们可以正常工作，但是它还允许用户输入小于起始日期"的截止日期"，我该如何比较两个日期以确保到日期"大于从日期".

感谢帮助，非常感谢

推荐答案

尝试使用 ^ ]

否则尝试这样的事情:

Try with DateTime.Compare Method[^]

Or else try something like this:

string s = "2012-10-01";
string t = "2012-10-16";

DateTime theDateA = DateTime.Parse(s);
DateTime theDateB = DateTime.Parse(t);

if (theDateB > theDateA)
{
   // Your code here
}
