Mvc 批量图片上传

首先导入文件(官网上下载 kindeditor )：

<link href="~/kindeditor-4.1.11-zh-CN/kindeditor/themes/default/default.css" rel="stylesheet" />
<script src="~/Scripts/jquery-1.10.2.js"></script>
<script src="~/kindeditor-4.1.11-zh-CN/kindeditor/kindeditor-all.js"></script>
<script src="~/kindeditor-4.1.11-zh-CN/kindeditor/lang/zh-CN.js"></script>

前台代码:

<script language="javascript" type="text/javascript">
    $(document).ready(function () {
        KindEditor.ready(function (K) {
            var editor = K.editor({
                uploadJson: '/Upload/UploadImage?SaveUrl=3',
                allowFileManager: true

            });
            K('#btn_selectImage').click(function () {
                editor.loadPlugin('multiimage', function () {
                    editor.plugin.multiImageDialog({
                        clickFn: function (urlList) {
                            var div = K('#div_imageView');
                            div.html('');
                            var arr = '';
                            K.each(urlList, function (i, data) {
                                arr = arr + data.url.substring(data.url.lastIndexOf("/") + 1) + ",";
                            });
                            editor.hideDialog();
                            div.html("图片上传成功");
                            $("#imgmuttle").val(arr);//这里得到的是图片名字的一组数组。[1.jpg,2.jpg......]并存放到<input type="hidden" id="imgmuttle" />中

                        }
                    });
                });
            });
        });

    });
</script>

<input type="button" id="btn_selectImage" value="批量上传">
<div id="div_imageView"></div>

后台接受图片方法:

   [HttpPost]
        public ActionResult UploadImage(int SaveUrl)
        {
            //string kks = Request["category_id"];
            string savePath = string.Empty;
            string saveUrl = string.Empty;

            switch (SaveUrl)
            {

                case 3:
                    savePath = "/UpdateFiles/" + DateTime.Now.ToString("yyyy-MM-dd") + "/";
                    saveUrl = "/UpdateFiles/" + DateTime.Now.ToString("yyyy-MM-dd") + "/";
                    break;
                default:
                    savePath = "/UpdateFiles/";
                    saveUrl = "/UpdateFiles/";
                    break;
            }

            string fileTypes = "gif,jpg,jpeg,png,bmp";
            int maxSize = 1000000;


            Hashtable hash = new Hashtable();

            HttpPostedFileBase file = Request.Files["imgFile"];

            if (file == null)
            {
                hash = new Hashtable();
                hash["error"] = 0;
                hash["url"] = "请选择文件";
                return Json(hash);
            }

            string dirPath = Server.MapPath(savePath);
            if (!Directory.Exists(dirPath))
            {
                Directory.CreateDirectory(dirPath);
            }


            string fileName = file.FileName;
            string fileExt = Path.GetExtension(fileName).ToLower();

            ArrayList fileTypeList = ArrayList.Adapter(fileTypes.Split(','));

            if (file.InputStream == null || file.InputStream.Length > maxSize)
            {
                hash = new Hashtable();
                hash["error"] = 0;
                hash["url"] = "上传文件大小超过限制";
                return Json(hash);
            }

            if (string.IsNullOrEmpty(fileExt) || Array.IndexOf(fileTypes.Split(','), fileExt.Substring(1).ToLower()) == -1)
            {
                hash = new Hashtable();
                hash["error"] = 0;
                hash["url"] = "上传文件扩展名是不允许的扩展名";
                return Json(hash);
            }
            string fileUrl = "";
            if (SaveUrl == 0)
            {
                string newFileName = DateTime.Now.ToString("yyyyMMddHHmmss_ffff", DateTimeFormatInfo.InvariantInfo) + fileExt;
                string filePath = dirPath + "tmep/" + newFileName;
                file.SaveAs(filePath);
                //fileUrl = saveUrl + Command.command.addWaterMark(filePath, fileExt, dirPath);
            }
            else
            {
                string newFileName = DateTime.Now.ToString("yyyyMMddHHmmss_ffff", DateTimeFormatInfo.InvariantInfo) + fileExt;
                string filePath = dirPath + newFileName;
                file.SaveAs(filePath);
                fileUrl = saveUrl + newFileName;

            }
            hash = new Hashtable();
            hash["error"] = 0;
            hash["url"] = fileUrl;

            return Json(hash, "text/html;charset=UTF-8"); ;
        }

效果：
