与asp.net MVC分页的搜索结果 [英] Paging search results with asp.net MVC

问题描述

我有一种情况，我不能在这里找到解决办法，可以我的搜索。下面是这种情况：

I have a situation that I couldn't find a solution for through my searches on here. Here is the scenario:

我有2必填字段，多个可选的人一个搜索表单。形式职位，以决定哪些字段选择并构建一个列表℃的操作方法;>符合搜索条件的对象。然后，我传递名单＆LT;>为显示视图

I have a search form with 2 required fields and multiple optional ones. The form posts to an action method that determines which fields are selected and builds a List<> of objects that match the search criteria. I then pass that List<> to the view for display.

这个问题我遇到涉及如何分页通常与asp.net的MVC实现。对于过去的项目我已经使用它创建的链接，其中包括查询参数，以及一个页参数的自定义HTML帮手。然后，它使用一个GET请求和。取（）跳过（）格式。

This issue I am running into involves how paging is typically done with asp.net mvc. For past projects I have used a custom Html helper that creates links which include the query parameters as well as a "page" parameter. It then uses a GET request and the .Take().Skip() format.

我已经打了一堵墙在这个项目上，我无法使用搜索条件的GET请求，我不能想出一个办法来保持列表＆LT招。

I've hit a wall on this project as I can't use a GET request for the search criteria and I can't figure out a way to keep the List<> in memory to do the usual "page" parameter trick.

我想过存储列表＆LT;>的会议，但对象和列表可能是非常大的。

I thought about storing the List<> in the session but the objects and the list could be very large.

我认为这是一个普遍的问题，具有先进的搜索形式，但我似乎无法找到一个很好的解决方案。任何帮助将是AP preciated。谢谢！

I would think this is a popular issue with advanced search forms but I can't seem to find a good solution. Any help would be appreciated. Thanks!

推荐答案

如何cacheing搜索结果对象，并给它一个唯一的密钥。那么你将有你的分页链接引用该唯一的（SearchID），并有你的行动看该对象，从缓存中把它和跳过/从那里。

How about cacheing the search result object and giving it a unique key. You would then have your paging links reference that unique (SearchID) and have your action look for that object, pull it from cache and Skip/Take from there.

这不会重建对象为每一个请求，使得网页加载速度更快，并降低对数据库/应用程序的压力。

This will not rebuild the object for every request, making page loading much faster and reducing strain on your database/application.

请注意：请确保缓存的对象上指定到期日

Note: Be sure you specify expiration date on the cached object.
