<form action="/Home/Upload" enctype="multipart/form-data" id="form2" method="post"> 
<input type="file" name="fileToUpload" id="fileToUpload2" multiple="multiple" /> 
<input type="submit" value="submit" /> 
</form> 

那在Asp.net MVC web application中，我们可以这么实现：

复制代码代码如下:

 
@using (Html.BeginForm("Upload", "Home", FormMethod.Post, new { enctype = "multipart/form-data", id = "form2" })) 
{ 
<label for="file">Upload Image:</label> 
<input type="file" name="fileToUpload" id="fileToUpload2" multiple="multiple" /> 
<input type="submit" value="Upload Image by submit" /> 
} 

假设这是一个HomeController下View, 即将提交到Upload的Action,看下面服务端的代码:

复制代码代码如下:

 
[HttpPost] 
public ActionResult Upload(HttpPostedFileBase[] fileToUpload) 
{ 
foreach (HttpPostedFileBase file in fileToUpload) 
{ 
string path = System.IO.Path.Combine(Server.MapPath("~/App_Data"), System.IO.Path.GetFileName(file.FileName)); 
file.SaveAs(path); 
} 

ViewBag.Message = "File(s) uploaded successfully"; 
return RedirectToAction("Index"); 
}
