How To Send Viewmodel And A File In Single Ajax Post Request, In Mvc 5?

I have an ASP.NET MVC 5 application. And I'm trying to send a POST request with the Model data, and also include user selected files. Here is my ViewModel (simplified for clarity):

Solution 1:

Here is what I test using with MVC5 and IE11 / chrome

View

<script>
    $(function () {
        $("#form1").submit(function () {
            /*You can also inject values to suitable named hidden fields*//*You can also inject the whole hidden filed to form dynamically*/
            $('#name2').val(Date); 
            var formData = newFormData($(this)[0]);
            $.ajax({
                url: $(this).attr('action'),
                type: $(this).attr('method'),
                data: formData,
                async: false,
                success: function (data) {
                    alert(data)
                },
                error: function(){
                    alert('error');
                },
                cache: false,
                contentType: false,
                processData: false
            });
            returnfalse;
        });
    });
</script><formid="form1"action="/Home/Index"method="post"enctype="multipart/form-data"><inputtype="text"id="name1"name="name1"value="value1" /><inputtype="hidden"id ="name2"name="name2"value="" /><inputname="file1"type="file" /><inputtype="submit"value="Sublit" /></form>

Controller

publicclassHomeController : Controller
{
    [HttpGet]
    public ActionResult Index()
    {
        return View();
    }

    [HttpPost]
    public ActionResult Index(HttpPostedFileBase file1, string name1, string name2)
    {
        var result = new List<string>();
        if (file1 != null)
            result.Add(string.Format("{0}: {1} bytes", file1.FileName, file1.ContentLength));
        else
            result.Add("No file");
        result.Add(string.Format("name1: {0}", name1));
        result.Add(string.Format("name2: {0}", name2));
        return Content(string.Join(" - ", result.ToArray()));
    }
}
