推荐答案

PreviousPage仅在跨页回发后才有效.除此之外，ASP.NET不知道最后一页是什么，怎么可能?您了解ASP.NET和Internet的工作原理吗?他们是无国籍的.每个请求都是唯一的，而不是链的一部分.您可以通过以下方式创建链:在会话中存储最后一页的名称，并在再次存储之前对其进行检查(检查事件和页面加载，将其存储在页面预呈现中是一种很好的模式).但是，首先要问自己为什么要知道，整个设计是否有问题?

PreviousPage only works after a cross page postback. Beyond that, ASP.NET can''t know what the last page was, how could it ? Do you understand how ASP.NET and the internet works ? They are stateless. Each request is unique and not part of a chain. You can CREATE a chain, by storing the name of the last page in the session, and checking it before you store it again ( check in events and page load, store in page prerender is a good pattern ). But, ask yourself first why you need to know, is there something wrong with your design as a whole ?

您尝试过Page.PreviousPage吗?
