控制器名 UploadTest

裡面新兩個Action, 分別為Upload()和SaveAs()

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.IO;

namespace UploadFileTest.Controllers
{
    public class UploadTestController : Controller
    {
        // GET: UploadTest
        public ActionResult Index()
        {
            return View();
        }


        //這個view是用來選擇上傳檔案的
        public ActionResult Upload()
        {
            return View();

        }

        //這個action是用來接收檔案並儲存在伺服器上
        [HttpPost]
       public ActionResult SaveAs(HttpPostedFileBase MyFile)
        {
            //得到的名字是檔案在本地機器的絕對路徑
            var strLocalFullPathName = MyFile.FileName;
            //提取出單獨的檔名，不需要路徑
            var strFileName = Path.GetFileName(strLocalFullPathName);
            //定義伺服器的資料夾，用來儲存檔案
            var strServerFilePath = Server.MapPath("/docs/");
            //將接收到檔案儲存在伺服器指定上當
            MyFile.SaveAs(Path.Combine(strServerFilePath,strFileName));

            //下面只是用來顯示一些相關字串做測試用
            ViewBag.strLocalFullPathName = strLocalFullPathName;
            ViewBag.strFileName = strFileName;
            ViewBag.strServerFilePath = strServerFilePath;

            return View();

        }

    }
}
 

Upload()方法的View檢視，要為form新增一個屬性： 

enctype="multipart/form-data"

注意: 紅色部分，第一是要用name的屬性，第二是這個名字要與SaveAs()的引數名相同

<form action="/UploadTest/SaveAs" method="post" enctype="multipart/form-data">
    <div>

        <input type="file" id="MyFile" name="MyFile" />
        <input type="submit" value="Upload" />
    </div>
</form>
 

SaveAs()方法的View檢視，只是檢視相關的字串

@ViewBag.strLocalFullPathName<Br />
@ViewBag.strFileName<br />
@ViewBag.strServerFilePath<br />
