ASP.NET MVC导出excel npoi

使用npoi组件

前端代码：

 @Html.ActionLink("导出Excel", "ExportWarehouseInOutDetailTable", new {warehouseInOutId = Model.Id},new {@class = "btn btn-primary pull-right"})

  @*ie8低版本以下不支持h5的formaction特性，故改用下一种方法。但这样有个小bug：修改查询条件后点击“导出Excel”只会导出条件未修改前的数据，但“查询”按钮无此问题*@
 @*<input type="submit" formaction="" class="btn btn-primary btn-small" value="导出Excel" />*@
 <a class="btn btn-primary btn-small" href="@("/WarehouseInOut/ExportTable?" + Request.QueryString.ToString())">导出Excel</a>

后端代码

         {
             Response.Clear();
             if (warehouseInOutId <= )

             }
             var model = _service.DetailIncludeDetailsAndGoods(warehouseInOutId);
             if (model.IsNull() || model.Id <= )
             {
                 Response.Write("<script>confirm('没有查询到任何数据！')</script>");
                 return;
             }

             Response.ContentType = "application/vnd.ms-excel";
             string fileName = string.Format("{0}_{1}.xls", model.StorageStatus.GetEnumDesc(), model.SerialId);
