推荐答案
您忘记在aspx页面中添加以下内容:
You forgot to add into your aspx page the following:
<head runat="server">
</head>
您的html标头必须为runat = server才能执行代码
Your html header must be runat=server in order to execute your code
实际上，这也会发生在其他任何属性上.
这是因为您正在检查的确具有定义但没有正确初始化的所有属性.
Actually this happens on any other property as well.
It is because you are checking a property which does have definition but not everything correctly initialized.
