如何在ChildAction删除的OutputCache？ [英] How to remove OutputCache on ChildAction?

问题描述

我想利用在.net MVC 3甜甜圈缓存功能对于我的主页，在我家的控制器，我有：

I am trying to take advantage of the donut caching features in .Net MVC 3. For my Home page, in my home controller, I have:

public ActionResult Index()
{
    return View();
}

[ChildActionOnly]
[OutputCache(Duration=3600)]
public ActionResult IndexMain()
{
    return PartialView(ViewModelRepository.GetIndexViewModel());
}

我我的看法，我有：

I my view, I have:

<% Html.RenderAction("IndexMain");%>

这一切工作正常。然而，当数据发生变化，我运行：

This all works fine. However, when the data changes, I run:

var urlToRemove = Url.Action("IndexMain", "Home");
Response.RemoveOutputCacheItem(urlToRemove);

该RemoveOutputCacheItem执行没有错误，但ChildAction缓存不会失效。有没有一种方法以编程方式从ChildAction删除缓存项？

The RemoveOutputCacheItem executes without an error, but the ChildAction cache is not invalidated. Is there a way to programmatically remove a cache item from a ChildAction?
