我的任务
分享请问一个关于Session的问题
请问
Session.Contents.Remove("abc");
Session["abc"]=null;
Session.Remove("abc");
有什么区别?
如果我想清空Session["abc"]的值,应该用哪个比较好?

1.Session.Contents.Remove("abc");
2.Session["abc"]=null;
3.Session.Remove("abc");
1 is same as 3, both remove an entry called "abc"
2 is different, if the entry "abc" doesn't exist, it is created, then the value is set to null
果你的目的除去abc，用3，如果你的目的是把abc对应的值设置成null，用2
