Html helper for <input type="file" />

Question

Is there a HTMLHelper for file upload? Specifically, I am looking for a replace of

<input type="file"/> 

using ASP.NET MVC HTMLHelper.

Or, If I use

using (Html.BeginForm())  

What is the HTML control for the file upload?

Answer 1

HTML Upload File ASP MVC 3.

Model: (Note that FileExtensionsAttribute is available in MvcFutures. It will validate file extensions client side and server side.)

public class ViewModel {     [Required, Microsoft.Web.Mvc.FileExtensions(Extensions = "csv",               ErrorMessage = "Specify a CSV file. (Comma-separated values)")]     public HttpPostedFileBase File { get; set; } } 

HTML View:

@using (Html.BeginForm("Action", "Controller", FormMethod.Post, new                                         { enctype = "multipart/form-data" })) {     @Html.TextBoxFor(m => m.File, new { type = "file" })     @Html.ValidationMessageFor(m => m.File) } 

Controller action:

[HttpPost] public ActionResult Action(ViewModel model) {     if (ModelState.IsValid)     {         // Use your file here         using (MemoryStream memoryStream = new MemoryStream())         {             model.File.InputStream.CopyTo(memoryStream);         }     } }
