I use this in my view: <input type="file" id="deploymentPackage" name="deploymentPackage" />

And in my controller, I do this:

public ActionResult AddRelease(ApplicationReleaseViewModel appRelease, HttpPostedFileBase deploymentPackage)
        {
            if (ModelState.IsValid)
            {
                ApplicationRelease dto = new ApplicationRelease();
                appRelease.UpdateDto(dto);

                using (StreamReader sr = new StreamReader(deploymentPackage.InputStream))
                {
                    dto.DeploymentPackage = new byte[deploymentPackage.InputStream.Length];
                    deploymentPackage.InputStream.Read(dto.DeploymentPackage, 0, dto.DeploymentPackage.Length);
                }

                this.ApplicationService.AddApplicationRelease(dto);

                return RedirectToAction("Index", new { ActionPerformed = "ApplicationReleaseAdded", Name = appRelease.Name.CutToMaxLength(50).UrlEncode() });
            }
            else
            {
                ViewBag.PostAction = "AddRelease";

                return View("EditRelease", appRelease);
            }
        }

UPDATE: Look at this link, if you can't abstract yourself from "my" code.

Yes, that is my own view model for that specific View/Action. Don't pay attention to that.
