[人生难得一只鸡]

PageObjectList[maxiPageNum - 1] 为空了？

试试
jingdiantuijian.PageType.RightPage page = PageObjectList[maxiPageNum - 1]==null? new jingdiantuijian.PageType.RightPage():PageObjectList[maxiPageNum - 1] as jingdiantuijian.PageType.RightPage;

[bdmh]

要么PageObjectList[maxiPageNum - 1]为空，要么page为空，调试看看吧

[宝_爸]

jingdiantuijian.PageType.RightPage page = PageObjectList[maxiPageNum - 1] as jingdiantuijian.PageType.RightPage;

PageObjectList[maxiPageNum - 1]为null了;
或者PageObjectList[maxiPageNum - 1]不是jingdiantuijian.PageType.RightPage的类型.造成page为null了。
