C# MVC ajax上传 文件

 用普通的ajax提交表单的时候,不能把文件流传到后端去,所以要用到jquery.form.js

  jquery.form.js到官网下载或者从这里下载:http://pan.baidu.com/s/1c2JS60C

view:

<script src="~/Scripts/jquery-1.7.1.min.js"></script>
<script src="~/Scripts/jquery.form.js"></script>
</head>
<body>
<form id="form1">
<input type="file" name="file"/>
<input type="button" value="提交" onclick="sub()" />
</form>
</body>
</html>
<script type="text/javascript">
function sub()
{
$("#form1").ajaxSubmit({
url: "@Url.Action("UploadFile", "Mydemo")",
type: "post",
success: function (data) {
//......
},
error: function (aa) {
alert(aa);
}
});
}
</script>

Controller:

 [HttpPost]
        public ActionResult UploadFile(HttpPostedFileBase file)
        {
           
            return Content("");
        }

下面这个

FormData上传文件，我当时用了 好像是不支持IE10以下

  var formData = new FormData();

        formData.append("filefloder", document.getElementById("filefloder").files[0])

        $.ajax({

            url: "@Url.Action("Upload", "UpdateManage")",

            type: "post",

            data: formData,

            contentType: false,

            processData: false,

            success: function () {

                alert("上传成功")

                location = location

            },

            error: function () {

                alert("上传失败")

            }

        })
