问题描述

是有可能都返回一个文件的下载和更新从控制器方法调用看法？

is it possible to both return a file for download and update a view from a controller method call?

或者需要一种解决方法，也许使用JavaScript（调用加载后的页面刷新）？

or a workaround is needed, maybe using javascript (calling a refresh of the page after loading)?

文件下载是在沿着一个视图模型的参数设置即时创建
（从各种控制搜索参数的页）。

the file download is created on the fly along the parameters set in a ViewModel (search parameters from various controls on the page).

您可以使用返回或视图模型从ViewData的你的行动文件的地址，并使用 window.location.href 作为您的视图的最后表现在以下code。

You can return the address of file using ViewModel or ViewData from your action, and use window.location.href as demonstrated in the following code at the end of your view.

控制器

public ActionResult Index()
{
    /* ... */

    ViewBag.FileName = "{FileName}";
    return View();
}

public ActionResult Download(string id) {
    /* ... */

    return File("{Path}", "{MIME type}", "{Desired file name}");
}

标记

<script type="text/javascript">

    window.location.href = "/home/download/" + "@Ajax.JavaScriptStringEncode(@ViewBag.FileName)";

</script>
