问题描述
我要上传文件中的 asp.net-MVC 。我如何使用HTML 输入文件
控制上传的文件?
I want to upload file in asp.net-mvc. How can I upload the file using html input file
control?
推荐答案
您不使用文件输入控制。服务器端控件未在ASP.NET MVC使用。签出以下博客帖子它说明了如何在ASP实现这一目标。 NET MVC。
You don't use a file input control. Server side controls are not used in ASP.NET MVC. Checkout the following blog post which illustrates how to achieve this in ASP.NET MVC.
所以,你会通过创建一个HTML表单,其中将包括文件输入启动:
So you would start by creating an HTML form which would contain a file input:
@using (Html.BeginForm("Index", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
<input type="file" name="file" />
<input type="submit" value="OK" />
}
然后你将有一个控制器来处理上传:
and then you would have a controller to handle the upload:
public class HomeController : Controller
{
// This action renders the form
public ActionResult Index()
{
return View();
}
// This action handles the form POST and the upload
[HttpPost]
public ActionResult Index(HttpPostedFileBase file)
{
// Verify that the user selected a file
if (file != null && file.ContentLength > 0)
{
// extract only the filename
var fileName = Path.GetFileName(file.FileName);
// store the file inside ~/App_Data/uploads folder
var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);
file.SaveAs(path);
}
// redirect back to the index action to show the form once again
return RedirectToAction("Index");
}
}
