如何创建zip并将其存储在链接MVC中或向用户提供zip并重定向

Question

I am able to create a zip with no problem, the only thing I cannot do, stock the zip file in a link so that when the user clicks on the link it will download the file

Response.Clear();
Response.ContentType = "application/zip";
Response.AddHeader("content-disposition", "filename=Photo.zip");

using (ZipFile zip = new ZipFile())
        {
            foreach (var pictures in pictureList)
            {
                zip.AddFile(Server.MapPath("~\\Content\\pictures\\upload\\" + pictures.name),"images");
            }
            zip.Save(Response.OutputStream);
        }
Response.End();

Code below works for the file downloading.

public void DownloadFile(string fileName)
 {
    FileInfo file = new FileInfo(@"D:\DOCS\"+fileName);
    Context.Response.Clear();
    Context.Response.ClearHeaders();
    Context.Response.ClearContent();
    Context.Response.AddHeader("Content-Disposition", "attachment;  filename=" + file.Name); Context.Response.AddHeader("Content-Length", file.Length.ToString());
    Context.Response.ContentType = "application/zip"; 
    Context.Response.Flush();
    Context.Response.TransmitFile(file.FullName);
    Context.Response.End();
}

However, Calling Response.Redirect after Response.End() will not going to work. If you really want to redirect the page you might have to think of an alternative way.
