可以練習黑大寫的文章 :
使用 C# 實現資料不落地加密 ZIP 壓縮-黑暗執行緒,使用 DotNetZip Library 套件。
這次環境為ASP.NET MVC FileResult跟Byte[],寫完發現代碼真的很精簡,之後小檔案壓縮情況不用再使用產生檔案+刪除方式了 
Controller :
暐翰
using System;
using System.Web.Mvc;
using System.Collections.Generic;
using Ionic.Zip;
using System.IO;
namespace ZipDemo
{
public class HomeController : Controller
{
[HttpGet]
public ActionResult Index()
{
return View();
}
[HttpPost]
public FileResult Download()
{
var bytes = default(byte[]);
using (var zip = new ZipFile())
{
zip.AddEntry("text.txt", new byte[] {});
zip.AddEntry("text\\text.txt", new byte[] {});
using (var ms = new MemoryStream())
{
zip.Save(ms);
bytes = ms.ToArray();
}
}
return File(bytes, System.Net.Mime.MediaTypeNames.Application.Zip);
}
}
}
View :
@{
Layout = null;
}
<!DOCTYPE html>
<html lang="en">
<head>
<!-- CSS Includes -->
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">

<body>
<div class="container">
<div class="col-md-6 col-md-offset-3">

@using (Html.BeginForm("Download","Home"))
{
<input type="submit" class="btn btn-success submit" />
}
</div>
