方法1：在列表页模板中通过c#的FileInfo对象来读取大小，参考：http://c.biancheng.net/view/2919.html
方法2：通过系统自带的方法，参考：http://www.pageadmin.net/help/60.cshtml
PageAdmin CMS-想到就能做到！

不能在此范围内声明名为“item”的局部变量

回复 3楼xiyou的帖子

读取大小 提示 NewsliList.cshtml(73): error CS0136: 不能在此范围内声明名为“item”的局部变量，因为这样会使“item”具有不同的含义，而它已在“父级或当前”范围中表示其他内容了！
