ASP.NET书籍信息录入实现代码

来源：醉满楼美食网

1、在数据库中建立一个test数据库，在test数据库中建立一个book_info表。
     Book_name      varchar(100)
       Author             varchar(50)
       Press               varchar(50)
       Press_date     varchar(20)
        Image            varchar(30)

2、制作一个如下页面：

当单击“插入图书信息”按钮时，将用户的信息保存到book_info表中。注意：封面图片要求先上传到网站根目录下的“upload”文件夹中，再将图片在网站中的相对路径保存到数据库book_info表的Image字段中。
