How to programmatically clear outputcache for controller action method

How to clear cache in specified controller?

I try to use several approaches:

Response.RemoveOutputCacheItem();
Response.Cache.SetExpires(DateTime.Now);

There is no any effect, it not work. 🙁
May be exists any way to get all keys in controller cache and remove they explicitly?
And in which overridden method i should perform clear cache? and how to do that?

Does any ideas?

try this:

put this on your Model:

public class NoCache : ActionFilterAttribute
{
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
        filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false);
        filterContext.HttpContext.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
        filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
        filterContext.HttpContext.Response.Cache.SetNoStore();

        base.OnResultExecuting(filterContext);
    }
}

and on your specific controller:
e.g:

[NoCache]
[Authorize]
public ActionResult Home()
 {
     ////////...
}
