普通上传
view:
<body>
<form id="form1" method="post" action="@Url.Action("UploadFile","Mydemo")" enctype="multipart/form-data">
<input type="file" name="file"/>
<input type="submit" value="提交" />
</form>
</body>
Controller:
[HttpPost]
public ActionResult UploadFile(HttpPostedFileBase file)
{
return Content("");
}
Ajax上传
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("");
}
