MVC4 C# - Want to save a image to a folder and saving the url in database

Question

I'm pretty new with MVC4 coding. Have been programming in SharePoint before.

The issue i have is that i want to save a image to a specific folder (Let say App_Data) and also save the url of the image to a string in a database. Would be great if anyone could help me with this issue.

The code i got right now is.

Models > ImageUpload.cs

public class ImageUpload

{
    public int ID { get; set; }
    public string Title { get; set; } 
    public string Url { get; set; }
}

public class ImageUploadDBContext : DbContext
{
    public DbSet<ImageUpload> ImageUploads { get; set; }
}

Controllers > ImageUploadController.cs

[HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create(ImageUpload imageupload)
    {
        if (ModelState.IsValid)
        {
            db.ImageUploads.Add(imageupload);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        return View(imageupload);
    }

[HttpPost]
    public ActionResult Upload(HttpPostedFileBase[] files)
    {
        foreach (HttpPostedFileBase file in files)
        {
            string picture = Path.GetFileName(file.FileName);
            string path = Path.Combine(Server.MapPath("~/App_Data"), picture);
            string[] paths = path.Split('.');
            string time = DateTime.UtcNow.ToString();
            time = time.Replace(" ", "-");
            time = time.Replace(":", "-"); 
            file.SaveAs(paths[0] + "-" + time + ".jpg");
        }
        ViewBag.Message = "File(s) uploaded successfully";
        return RedirectToAction("Index");
    }

View > ImageUpload > Index.cshtml

@{
ViewBag.Title = "Index";
}

<h2>Index</h2>

<p>
    @Html.ActionLink("Create New", "Create")

Solution

For file uploading, you can use this code. Image saved to folder and filename stored to database:

In controller:

[HttpPost]
public ActionResult Create(EventModel eventmodel, HttpPostedFileBase file)
{ 
   if (ModelState.IsValid)
   {
      var filename = Path.GetFileName(file.FileName);
      var path = Path.Combine(Server.MapPath("~/Uploads/Photo/"), filename);
      file.SaveAs(path);
      tyre.Url = filename;

      _db.EventModels.AddObject(eventmodel);
      _db.SaveChanges();
      return RedirectToAction("Index");
   }
   return View(eventmodel);
}

And View:

<div>
   Image
   <input type="file" name="file" id="file" />
   @Html.HiddenFor( model => model.ImageUrl)
   @Html.ValidationMessageFor( model => model.Url )
</div>
