推荐答案

我不太惊讶-我不会认为您无法通过静态方法显示警报，因为它不知道要使用哪个会话:它是静态的，并且没有会话.
我怀疑正是出于这个原因，HttpContext.Current.CurrentHandler返回null.

I''m not too surprised - I don''t think you can display an alert from a static method, as it doesn''t know which session to use: it''s static, and doesn''t have a Session.
I suspect that HttpContext.Current.CurrentHandler is returning null for just that reason.
