问题描述
我要创建一些Excel表格，并将其发送给用户的页面ASP.net。问题是，有时我得到的，因为要求的运行速度比executionTimeout长（每默认110秒）。
I'll have an ASP.net page that creates some Excel Sheets and sends them to the user. The problem is, sometimes I get Http timeouts, presumably because the Request runs longer than executionTimeout (110 seconds per default).
我只是想知道我的选择是，以prevent这一点，不想要一般增加executionTimeout在的web.config ？
I just wonder what my options are to prevent this, without wanting to generally increase the executionTimeout in web.config?
在PHP中，存在它可以在函数中使用以延长其使用寿命，但我没有看到在C＃这样的事情/ ASP.net？
In PHP, set_time_limit exists which can be used in a function to extend its life, but I did not see anything like that in C#/ASP.net?
你是如何处理在ASP.net长期运行的功能？
How do you handle long-running functions in ASP.net?
推荐答案
如果你想增加执行超时您可以设置此一个请求
If you want to increase the execution timeout for this one request you can set
HttpContext.Current.Server.ScriptTimeout但你仍然可以在客户端定时的问题出来了，你不能可靠地直接从服务器解决。要解决这个问题，你可以实现一个处理页面（如罗布建议）这回发，直到响应准备。或者你可能想看看AJAX做类似的事情。
But you still may have the problem of the client timing out which you can't reliably solve directly from the server. To get around that you could implement a "processing" page (like Rob suggests) that posts back until the response is ready. Or you might want to look into AJAX to do something similar.
