form表单一次上传多种类型的图片（每种类型的图片可以上传多张）

controller中的action方法

public ActionResult UploadImage( )
        {

　　　　 int imageType=(int)Request.Form["ImageType"];

　　　　 //整体图片集合
            IList<HttpPostedFileBase> wholePictureIList = Request.Files.GetMultiple("WholePicture");//HttpPostedFileBase:充当类的基类，这些类提供对客户端上传的文件的单独访问;Request.Files.GetMultiple(string name):返回与name匹配的所有文件

　　　　 //周边图片集合
            IList<HttpPostedFileBase> AroundSupportPictureIList = Request.Files.GetMultiple("AroundSupportPicture");

if (wholePictureIList[0].FileName != "")
            {
                foreach (var item in wholePictureIList)
                {
                    byte[] b = new byte[item.ContentLength];
                    item.InputStream.Read(b, 0, item.ContentLength);
                    model.WholePicture.Add(b);//model.WholePicture是byte[]的集合，即图片的流文件，可以存到数据库中
                }
            }
            if (AroundSupportPictureIList[0].FileName != "")
            {
                foreach (var item in AroundSupportPictureIList)
                {
                    byte[] b = new byte[item.ContentLength];
                    item.InputStream.Read(b, 0, item.ContentLength);
                    model.AroundSupportPicture.Add(b);
                }
            }
            int userId = (int)Session["UserId"];
            ManageParkPediaService service = new ManageParkPediaService();
           StateInfo<int> infoT = service.SaveImage(model, userId);
           return Json(infoT);
        }

view中的代码

引入<script src="~/Scripts/jquery.form.js"></script>

<script type="text/javascript">
        //上传图片
        function uploadImage() {

            console.log(222);
            $('#fileForm').ajaxSubmit({
                success: function (msg) {
                    console.log(msg);
                }

            });
        }
</script>

<form id="fileForm" method="post" action="http://localhost:38594/UploadImage/SaveImageResult" enctype="multipart/form-data">

　　　　<input type="text" name="ImageType" id="ImageType" value="1" />
            <input type="file" name="WholePicture" id="WholePicture" readonly multiple />

　　　　<input type="file" name="AroundSupportPicture" id="AroundSupportPicture" readonly multiple />
            <input type="button" onclick="uploadImage()" value="上传图片" />
