How to post an array of files in ASP.NET MVC 3?

Question

I would like to be able to post multiple files in one form. I would like to pass these files as an array of files. For example I would like to do this.

<input type="file" name="files[0]" />
<input type="file" name="files[1]" />
<input type="file" name="files[2]" />

Then I would like to be able to receive these files as an array in the Controller. I've tried this.

public ActionResult AddPart(HttpPostedFileBase[] files)

But that doesn't work. I've googled it but all I can find is examples on uploading one file. Does anyone know how to do this using MVC3 C#.

If you want to upload not only one file, you need to use enctype="multipart/form-data" in your form.

@using (Html.BeginForm("", "Client", FormMethod.Post, new {enctype="multipart/form-data"}))

And controller:

[HttpPost]
public ActionResult AddPart(IEnumerable<HttpPostedFileBase> files)

All other parts is ok.

Is there something else that I could be missing because what you posted as a solution didn't seem to work.

Well i got almost a same case. But that is for nested array of files.

using IEnumerable as an array([ ]) solved my problem. [] s

[HttpPost]
public ActionResult AddPart(IEnumerable<HttpPostedFileBase>[] files)
