  Response.Write("<script>alert('添加成功！');location.href='teacher5.aspx';</script>")

[解决办法]
[file] 试试
[解决办法]
sql关键字加 []
sqlstr = "insert into [file](score) values('" + TextBox2.Text + " ')"
[解决办法]

SQL code

insert into [File](score) values('ss')
[解决办法]
SQL code
INSERT INTO [file]([score])VALUES('123')
