推荐答案

无论你做什么都听起来像个坏主意。您可能想重新考虑自己在做什么。例如，当移动到另一个表单时，将信息保存在数据库中，然后在查询字符串中传递一个id。



但是，如果你确实需要知道你来自哪个页面可以使用Request.ServerVariables [HTTP_REFERER]或Request.UrlReferrer。或者你总是可以在查询字符串中添加另一个参数来表示你需要的东西。

First off, whatever you are doing sounds like a bad idea. You may want to rethink what you are doing. For example, when moving to another form, save the information in the database and then pass a single id through in the query string.

However, if you do need to know which page you are coming from you can use Request.ServerVariables["HTTP_REFERER"] or Request.UrlReferrer. Or you could always put another parameter in the querystring to indicate what you need.

你在Querystring上传递参数，那时你也必须提到webform。那么为什么你担心其他形式，你指向特定的网络形式，而重定向时间，然后你有什么疑问？

You are passing parameters over Querystring at that time you have to mentioned the webform also. Then why do you worry about other forms, your pointing the particular webform while redirect time then what's your doubt in that?
