C# 导出Excel表格

function exportExcel()
        {
            //查询条件
            var startTime = F.ui.startTime.getText() == "" ? null : F.ui.startTime.getText();
            var endTime = F.ui.endTime.getText() == "" ? null : F.ui.endTime.getText();
            var major = F.ui.major.getText() == "" ? "" : F.ui.major.getText();
            var Department = F.ui.Department.getText() == "" ? "" : F.ui.Department.getText();
            var ReportPerson = F.ui.ReportPerson.getText() == "" ? "" : F.ui.ReportPerson.getText();
            var RectPerson = F.ui.RectPerson.getText() == "" ? "" : F.ui.RectPerson.getText();

            var data = "startTime=" + startTime + "&endTime=" + endTime + "&major=" + major + "&Department=" + Department + "&ReportPerson=" + ReportPerson + "&RectPerson=" + RectPerson;
            download('Export', data, 'post');
        }
        function download(url, data, method)
        {
            if (url && data) {
                data = typeof data == 'string' ? data : jQuery.param(data);
                var inputs = '';
                $.each(data.split('&'), function () {
                    var pair = this.split('=');
                    inputs += '<input type="hidden" name = "' + pair[] + '" value ="' + pair[] + '">';
                });
                $('<form action = "' + url + '" method ="' + (method || 'post') + '">' + inputs + '</form>').appendTo('body').submit().remove();
            }
        }

后台接收方法添加NOPI引用

 public FileStreamResult Export(HiddenDangerDto input)
        {
            int recordCount = ;
            var list = HiddenDangerService.GetAll(input, , Int32.MaxValue, out recordCount);
            HSSFWorkbook book = ExportExcel.GridToExcelByNPOI<HiddenDangerDto>(list);
            System.IO.MemoryStream ms = new System.IO.MemoryStream();
            book.Write(ms);
            ms.Seek(, System.IO.SeekOrigin.Begin);
            var cookie = new HttpCookie("time");
            cookie.Values.Add("time", "");
            Response.AppendCookie(cookie);
            return File(ms, "application/vnd.ms-excel", DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls");
        }

类必须加[Display(Name = "")]

public class HiddenDangerDto
    {
        public int ID { get; set; }
        [Display(Name = "时间")]
        public DateTime Time { get; set; }
        [Display(Name = "专业")]
        public string major { get; set; }
        [Display(Name = "部门")]
        public string Department { get; set; }
        [Display(Name = "隐患上报人")]
        public string ReportPerson { get; set; }
        [Display(Name = "整改责任人")]
        public string RectPerson { get; set; }
        [Display(Name = "隐患描述")]
        public string Description { get; set; }
        [Display(Name = "整改措施")]
        public string RectMeasures { get; set; }
    }
