var dailyReports=（来自db.dailyReports中的dr
其中，dr.DailReportDate>=开始日期
&&dr.DailyReportDate我建议您在控制器中计算总和，然后扩展模型，将该值单独包含到表数据中。这样，视图只显示从服务器发送的数据，而不是动态计算值。这也将提高页面的性能。我建议在jQuery中使用DataTables | Table插件，这是一个开源插件，或者类似的东西，而不是为每个控制器重新发明轮子。

这将适用于所有类型的表格数据
您可以在此处看到它们是如何合计的：

这还将为您带来其他好处，如分页和开箱排序。
请指定您的意思。您是想对某列在DB中的每个值求和，还是只想将控制器发送的数据相加？您可以使用简单的lambda扩展方法Model.sum（item=>item.totalcashstack）
（只是提示，我不熟悉asp）只需将控制器发送的数据相加，例如TotalCashStack列的值，并将该值显示在标题行中。请不要盲目复制/粘贴整个文档。如果您将其限制为相关代码，人们会更倾向于帮助您。越多越好：）作为关于这个问题的更一般的提示：int total=MyObjects.Select（myObj=>myObj.SomeNumber）
。传递计算值最好通过ViewBag或ViewModel完成。两者都可以，但最好在同一应用程序中保持一致。
