Question

在Mono MVC5中，下面的控制器代码用于返回自定义错误页面：

    public ActionResult Details(string id, string product)
    {
       ....
        if (productNotFound) {
            // http://www.eidias.com/blog/2014/7/2/mvc-custom-error-pages
            Response.Clear();
            Response.TrySkipIisCustomErrors = true;
            Response.Write(product + " product not exists");
            Response.StatusCode = (int)HttpStatusCode.NotFound;
            Response.End();
            return null;
        }

这会导致可能在Application_Error中捕获的ThreadAbortException。看起来线程会继续运行，直到达到超时。

如何解决这个问题，以免发生异常？

SO中的答案需要在不同的地方进行web.config修改和大量代码。

我正在寻找一种简单的方法来返回自定义错误页面而不在MVC5中进行web.config修改。

如何终止控制器中的thred或是否有其他方法可以避免异常。从Applicaion_Error记录异常，如果日志文件不包含此类异常，则会出现异常。
