HttpPostedFileBase不附加文件

Question

当我选择图像时，它会预览它，当我选择更多图像时，它会在它们旁边预览，然后我点击上传图像提交按钮，它只会上传最后选择的图像，而不是第一个。

    [HttpPost]
    public ActionResult Index(IEnumerable<HttpPostedFileBase> files)
    {
        try
        {
            /*Lopp for multiple files*/
            foreach (var file in files)
            {
                /*Geting the file name*/
                string filename = System.IO.Path.GetFileName(file.FileName);
                /*Saving the file in server folder*/
                file.SaveAs(Server.MapPath("~/Images/" + filename));
                string filepathtosave = "Images/" + filename;
                /*HERE WILL BE YOUR CODE TO SAVE THE FILE DETAIL IN DATA BASE*/
            }

            ViewBag.Message = "File Uploaded successfully.";
        }
        catch
        {
            ViewBag.Message = "Error while uploading the files.";
        }
        return View();
    }

<script>
    var inputLocalFont = document.getElementById("image-input");
    inputLocalFont.addEventListener("change", previewImages, false);

    function previewImages() {
        var fileList = this.files;

        var anyWindow = window.URL || window.webkitURL;

        for (var i = 0; i < fileList.length; i++) {
            var objectUrl = anyWindow.createObjectURL(fileList[i]);
            $('.preview-area').append('<img src="' + objectUrl + '" style="height:150px; width:150px; margin:20px" />');
            window.URL.revokeObjectURL(fileList[i]);
        }

        //$(inputLocalFont).hide();
        //inputLocalFont = $('<input type="file" class="dimmy" multiple />').appendTo("#filecontainer").get(0);
        //inputLocalFont.addEventListener("change", previewImages, false);
    }


</script>



@using (Html.BeginForm("Index", "Home", null, FormMethod.Post, new { @enctype = "multipart/form-data" }))
{
    <h3>Multiple file upload with asp.net MVCc/MVC3/MVC4/MVC5, C# and HTML5 </h3>
    <input type="file" name="files" id="image-input" value="" multiple="multiple" />
    <input type="submit" value="Upload You Image" title="Uplad" />
    <div style="color: Red; font-size: 14px">@ViewBag.Message</div>
    <br />
    <br />
    <div class="preview-area"></div>

}

所以请帮帮我..
