推荐答案

您可以把这个应用程序缓存，这样就可以从任何地方访问它。

You can put this in the Application cache so that you can access it from anywhere.

HttpContext.Current.Application["productdetial"] = productdetial;

然后，你可以这样从任何地方访问它。

Then you can access it from anywhere like this

ProductDetails object = (ProductDetails) HttpContext.Current.Application["productdetial"]

如果你想存储和检索这样的字符串比也这是可能的。请注意，如果你需要缓存特定于用户会话，然后使用会话表，而不是应用程序

if you want to store and retrieve this a string than also this is possible. Note that if you need caching specific to user session then use "Session" table instead of "Application"

有是缓存的OutputCache的另一种类型的可在控制器操作如下被应用。为300秒的持续时间，这将提供缓存输出到客户端。

There is another type of cache OutputCache that can be applied on controller action as shown below. For duration of 300 seconds this will provide the cached output to the client.

[OutputCache(Duration=300, VaryByParam="none")]
 public ActionResult GetProductDetails()
 {
      //Fetch the data once and it will be cached for 300 seconds       
            return View(data);
 }

看起来你需要上述2之一还有其他类型的缓存也喜欢甜甜圈缓存和甜甜圈洞的缓存，如果你只想要查看的某些部分会被缓存，均适用。在甜甜圈洞缓存可以包括上述缓存动作转换成另一种观点作为行动。

Looks like you need one of the above 2. There are other types of caching also like donut caching and donut hole caching which are applicable if you want only some portion of the view to be cached. In donut hole caching you can include the above cached action into another view as a action.
