前台：用Uploader插件写好前台

 var uploader1 = null;
    var uploadExcelUrl = ‘@Url.Action(uploadAction, controllerName)‘;//后台获取前台导入的文件

function InitUploader() {
        uploader1 = $.fn.cfwinUploader.upload({
            //baseUrl: ‘/Scripts/cfw.webuploader/‘,
            postUrl: uploadExcelUrl,
            // 定义按钮
            btnAddFile: $(‘#uploadExcel‘),
            // 设置上传类型，0为图片，1为文件，2为文件和图片
            type: 1,
            // 限制文件个数
            fileNumLimit: 10,
            // 请求参数
            params: { tenatName: ‘‘, blobId: ‘‘ },
            // 文件限制
            configure: {
                fileMaxSize: 15,
                fileExt: ‘xls,xlsx‘,
            },
            // 回调方法
            callback: {
                // 上传过程中触发
                uploadProgress: function (file, percentage) {
                    $("#" + file.id + " .progress-bar").css(‘width‘, (percentage * 100).toFixed(2) + "%");
                },
                uploadComplete: function (file) { //不管成功或者失败，文件上传完成时触发
                },
                uploadSuccess: function (file, data) {
                    uploader1.reset();
                    if (data) {
                        if (data.hasOwnProperty("success")) {
                            if (data.success) {
                                if (data.Result.length > 0) {
                                    data.Result.forEach(function(el, index) {
                                   
                                    });
                                    $.messager.showInfoCenter(‘系统提示‘, ‘上传数据成功！‘);
                                }
                            } else {
                                $.messager.showErrorCenter(‘错误消息‘, data.message);
                            }
                        } else {
                            $.messager.alert(‘系统提示‘, "抱歉,你不具有当前操作的权限！", ‘error‘, function () {
                                //window.location.href = window.location.href;
                            });
                        }
                    } else {
                        $.messager.showErrorCenter(‘错误消息‘, ‘上传数据失败！‘);
                    }
                    $(‘#datagrid‘).datagrid(‘reload‘);
                    $(‘#‘ + file.id).remove();
                },
                uploadError: function (file, reason) {
                    $.messager.showErrorCenter(‘错误消息‘, ‘上传数据失败，失败原因：‘ + reason);
                },
                onFileQueued: function (file) {
                    uploader1.upload();
                }
            }
        });
    }

 

后台： //导入
        //上传组件
        public JsonResult uploadAction(HttpPostedFileBase file, string detailList = null)
        {
            var json = new JsonSerializer();
            var list = new List<StoreOtherInDetailDTO>();
            if (detailList != null)
            {
                JsonReader reader = new JsonTextReader(new StringReader(detailList));
                list = json.Deserialize<List<StoreOtherInDetailDTO>>(reader);
            }
            return GetServiceJsonResult(() =>
            {
                var result = ScmService.OtherInExcelTemplate(file.InputStream, list);//Service层处理具体代码
                return result;
            });
        }
