当尝试在asp.net应用程序中打开特定页面时，我得到了一个YSOD：
Server Error in '/CommonLoon' Application.
Parser Error

首先，为什么注释掉的一行有问题？
其次......其次是第二个：那个文件没有（或不再）有评论;相反，它现在就在那条线上：
<!-- 5/6/2013: Replace 1.8.16 with a newer css, such as http://code.jquery.com/ui/1.10.2/themes/smoothness/jquery-ui.css? The "custom" part of the name of the file makes me hesitate to make a change, though... -->
该文件的旧版本来自哪里？短语“可能想要”并没有出现在解决方案的任何地方...... ???
陌生人;我刚刚取消注释了一些迄今为止已经注释掉jQjuery以测试旧功能，并且没有注意到有一条注释应该阻止代码编译，即：
$("#BeginDate").datepicker( try this as a anytime date component
......然而它已编译并运行！天堂到Murgatroid！怎么了？？？！？
