MVC使用ExcelPackage导出Excel文件

 IPageOfItems<OrderCash> OrderCashList = Entity.Selects<OrderCash>(p);

string tempname = "bank.xlsx";  //定义好的导出模板
string file = Server.MapPath("/template") + "\\" + tempname;  //模板存放路径
ExcelPackage package = new ExcelPackage(new FileInfo(file), true);  //实例化

if (OrderCashList.Count() > 0)
{
     //加载模板第一张表
     var sheet = package.Workbook.Worksheets[1];

     var cells = sheet.Cells;
     int Rows = OrderCashList.Count();
     int Befor = 2;//从第几行开始，行号从1开始
     sheet.InsertRow(Befor + 1, Rows - 1, Befor);
     int i = Befor;
     foreach (var item in OrderCashList)
     {
          //业务参考号
          cells["A" + i].Value = item.OId;
          cells["B" + i].Value = "";
          cells["C" + i].Value = "";
          cells["D" + i].Value = "";
          cells["E" + i].Value = "";
          cells["F" + i].Value = item.CardNum;
          cells["G" + i].Value = item.Owner;
          cells["H" + i].Value = item.Bin;
          cells["I" + i].Value = item.Amoney - (decimal)item.UserRate;
          cells["J" + i].Value = "人民币";
          cells["K" + i].Value = "";
          cells["L" + i].Value = "";
          cells["M" + i].Value = "";
          cells["N" + i].Value = item.Mobile;
          cells["O" + i].Value = "";
          i++;
     }
}

 Response.BinaryWrite(package.GetAsByteArray());//输出
 Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
 Response.AddHeader("content-disposition", "attachment;  filename=" + DateTime.Now.ToString("yyyyMMddHHmmss") + new Random().Next(10, 99) + ".xlsx");
