Check out this tutorial to return different action result.

The ASP.NET MVC framework supports several types of action results including:

I'd done something similar what you want on MVC 5 and I used FilePathResult as J.W said.

我在MVC 5上做了类似你想要的东西,我使用了FilePathResult,就像J.W所说的那样。

cshtml:

@Html.ActionLink("Download Here", "DownloadExampleFiles", "Product", new { fileName = "variation-example" }, new { @target = "_blank" })

ProductController:

public FilePathResult DownloadExampleFiles(string fileName)
{
    return new FilePathResult(string.Format(@"~\Files\{0}", fileName + ".txt"), "text/plain");
}

Download a file seems to be very silly/easy, however, for those who are new on MVC, it's not. This approach sounds to be the best while using MVC.

下载一个文件似乎非常愚蠢/容易,然而,对于那些刚接触MVC的人来说,事实并非如此。使用MVC时,这种方法听起来是最好的。

PS: I've forced a .txt just as an example. You should do what is intersting for you to get the specific file.

PS:我强迫.txt就是一个例子。您应该为您获取特定文件的内容。

AFAIK, there is nothing special about doing this in MVC. Create a LinkButton on your form with a handler that generates the PDF file, then redirect to the created file.

AFAIK,在MVC中这样做没有什么特别之处。使用生成PDF文件的处理程序在表单上创建LinkButton,然后重定向到创建的文件。

Something like this maybe:

这样的事情可能是:

<h2>List Of Reports</h2>
<ul>
    <% foreach (var report in Model){ %>
        <li><a href="<%= Html.BuildUrlFromExpression<ReportController>(r => r.Reports(report.Filename)) %>"><%=report.Filename %></a></li>
    <% } %>
</ul>

There maybe a shorter way but this works.

可能有一个较短的方法,但这是有效的。
