推荐答案

会话用于TempData存储. TempData是会话状态的一种非常有限的形式，它将仅持续到特定用户的下一个请求为止. (在MVC 2+中进行编辑，一直持续到下一次读取为止.)TempData的目的是存储数据，然后进行重定向，并使所存储的数据可用于您刚刚重定向到的操作.

将Session用于TempData存储意味着已处理Session的任何分布式缓存系统都将适用于TempData.在TempData可以使用时避免直接使用Session有很多好处.一种是您不必自己清理会话；另一种是您无需自己清理会话. TempData将过期"到

Session is used for the TempData store. TempData is a highly limited form of session state which will last only until the next request from a certain user. (Edit In MVC 2+, it lasts until it is next read.) The purpose of TempData is to store data, then do a redirect, and have the stored data be available to the action to which you just redirected.

Using Session for the TempData store means that any distributed caching system which already handles Session will work for TempData. Avoiding using Session directly when TempData will do has a couple of advantages. One is that you don''t have to clean up the Session yourself; TempData will "expire" on its own.
