movies = movies.Where(x => x.Genre problem

[ixlin]

Translation

When I followed the documentation and implemented the method of filtering movies based on the type selected in the drop-down box, I selected "ALL" and nothing was displayed. At this time, I realized a small problem in the code and modified the following code:
if(!String.IsNullOrEmpty(movieGenre) && movieGenre!= "ALL"){ movies = movies.Where(x => x.Genre == movieGenre); }
I hope the teacher can understand this problem. If you can give better suggestions, I would be very grateful.

Description

当我根据文档教材，实现根据下拉框选择的类型筛选电影后，我选择了“ALL”，结果什么也没有显示，这时候我意识到代码中的一个小问题，然后修改了下面这段代码：
if(!String.IsNullOrEmpty(movieGenre) && movieGenre!= "ALL"){ movies = movies.Where(x => x.Genre == movieGenre); }
希望老师能理解这个问题，如能给出更好的建议，那就太感谢了。
good luck
