我试图使用这里提到的一个例子如何用multipart/form-data做一个ASP.NET MVC Ajax表单帖子？

但我一直收到"失败"错误消息框

Index.cshtml

<script src="~/Scripts/jquery-1.8.2.min.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.min.js"></script>
<h2>Files Upload</h2>
<script type="text/javascript">
$(function() {
    $("#form0").submit(function(event) {
        var dataString;
        event.preventDefault();
        var action = $("#form0").attr("action");
        if ($("#form0").attr("enctype") == "multipart/form-data") {
            //this only works in some browsers.
            //purpose? to submit files over ajax. because screw iframes.
            //also, we need to call .get(0) on the jQuery element to turn it into a regular DOM element so that FormData can use it.
            dataString = new FormData($("#form0").get(0));
            contentType = false;
            processData = false;
        } …
