• It is possible with FormData, but this solution may not run in some old browser versions like IE9. If you are only targeting new browsers, I can give you solution. – ramiramilu Commented Jul 5, 2015 at 6:31

Here goes the solution using FormData. One caveat with this solution is that FormData support is only available in modern browsers, so do not expect this to work with old browsers like IE7 - 9 etc.

Create a controller action in following way -

public JsonResult GetFormData(HttpPostedFileBase file, string Name)
{
    return Json(true);
}

Then your HTML would be -

<script src="~/Scripts/jquery-1.10.2.min.js"></script>

<script>
    $(function () {
        $("#btnSubmit").click(function () {
            $.ajax({
                url: "/Home/GetFormData",
                type: "POST",
                data: function () {
                    var data = new FormData();
                    data.append("name", jQuery("#name").val());
                    data.append("file", jQuery("#file").get(0).files[0]);
                    return data;
                }(),
                contentType: false,
                processData: false,
                success: function (response) {                        
                },
                error: function (jqXHR, textStatus, errorMessage) {
                    console.log(errorMessage);
                }
            });
        });
    });
</script>    

Name : <input type="text" id="name" /> <br />
File: <input type="file" id="file" /> <br />
<input type="button" value="Click" id="btnSubmit" />

When the view is rendered and entered with some information -

When you click button, Output would be -
