使用 DotNetZip 通过 ASP.NET MVC 下载 zip 文件 [英] Downloading of zip file through ASP.NET MVC using DotNetZip

问题描述

我在一个文件夹中创建了一个文本文件并压缩了该文件夹并保存了@same 位置以供测试.我想在创建后直接在用户计算机上下载该 zip 文件.我正在使用 dotnetzip 库并完成了以下操作:

I have created a text file in a folder and zipped that folder and saved @same location for test purpose. I wanted to download that zip file directly on user machine after it is created. I am using dotnetzip library and have done following:

Response.Clear();
Response.ContentType = "application/zip";
Response.AddHeader("content-disposition", "filename=" + "sample.zip");
using (ZipFile zip = new ZipFile())
{
    zip.AddDirectory(Server.MapPath("~/Directories/hello"));
    zip.Save(Server.MapPath("~/Directories/hello/sample.zip"));
}

有人可以建议如何在用户端下载 zip 文件吗?

Can someone please suggest how the zip file can be downloaded at user's end.?

推荐答案

你可以使用控制器的 File 方法返回一个文件，比如:

You may use the controller's File method to return a file, like:

public ActionResult Download()
{
    using (ZipFile zip = new ZipFile())
    {
        zip.AddDirectory(Server.MapPath("~/Directories/hello"));
        zip.Save(Server.MapPath("~/Directories/hello/sample.zip"));
        return File(Server.MapPath("~/Directories/hello/sample.zip"), 
                                   "application/zip", "sample.zip");
    }
}

如果不需要另外存储zip文件，则不必将其写入服务器上的文件中:

If the zip file is not required otherwise to be stored, it is unnecessary to write it into a file on the server:

public ActionResult Download()
{
    using (ZipFile zip = new ZipFile())
    {
        zip.AddDirectory(Server.MapPath("~/Directories/hello"));

        MemoryStream output = new MemoryStream();
        zip.Save(output);
        return File(output.ToArray(), "application/zip", "sample.zip");
    }  
}
