文件上传ASP.NET MVC 3.0 [英] File Upload ASP.NET MVC 3.0

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");        
    }
}
