控制器名 UploadTest
里面新两个Action, 分别为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();
}
//这个view是用来选择上传文件的
public ActionResult Upload()
{
return View();
}
//这个action是用来接收文件并保存在服务器上
[HttpPost]
public ActionResult SaveAs(HttpPostedFileBase MyFile)
{
//得到的名字是文件在本地机器的绝对路径
var strLocalFullPathName = MyFile.FileName;
//提取出单独的文件名,不需要路径
var strFileName = Path.GetFileName(strLocalFullPathName);
//定义服务器的文件夹,用来保存文件
var strServerFilePath = Server.MapPath("/docs/");
//将接收到文件保存在服务器指定上当
MyFile.SaveAs(Path.Combine(strServerFilePath,strFileName));
//下面只是用来显示一些相关字符串做测试用
ViewBag.strLocalFullPathName = strLocalFullPathName;
ViewBag.strFileName = strFileName;
ViewBag.strServerFilePath = strServerFilePath;
return View();
}
}
}
Upload()方法的View视图,要为form添加一个属性:
enctype="multipart/form-data"
注意: 红色部分,第一是要用name的属性,第二是这个名字要与SaveAs()的参数名相同
<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视图,只是查看相关的字符串
@ViewBag.strLocalFullPathName<Br />
@ViewBag.strFileName<br />
@ViewBag.strServerFilePath<br />
