} 1.后台Response.Redirect(Default2.aspx?key值); 2.Form表单会通过submit按钮自动提交数据将数据提交给action设置的页面中去method“get”方式来提交 method 提交方式 action 目标页面 get提交方式 % Page LanguageC# AutoEventWireuptrue CodeFileDefault1.aspx.cs InheritsDefault1 EnableViewStateMacfalse %!DOCTYPE htmlhtml xmlnshttp://www.w3.org/1999/xhtml

} post提交方式 - 直接数据提交方式 除了不在地址栏拼接数据其它的没有任何区别3、Session就是一个临时保存数据的对象保存在服务器可以理解为容器变量 可以存Object类型一个连接为独立的一组默认生命周期为20分钟如果在这20分钟内重新进行数据提交或是页面刷新都会重置这20分钟倒计时时间。 如果Session[键]里面没有内容的时候使用时会抛出异常所以一定要在使用session的值之前判断此是否为空。 注意Session不要过度使用因为放的东西太大了用户连接多了就会导致内存溢出服务器崩溃也不要不使用会造成资源浪费因为内存中的数据是最快速的 % Page LanguageC# AutoEventWireuptrue CodeFileDefault3.aspx.cs InheritsDefault3 %!DOCTYPE htmlhtml xmlnshttp://www.w3.org/1999/xhtml

} 4、cookie临时保存数据的一个对象保存在客户端不要保存很重要的信息因为会随时被用户删掉有些程序会自动抓取用户电脑上的cookie信息如果密码保存进去了就会被抓取到 赋值使用Response对象 1、Response.Cookies.Add(new HttpCookie(键, 值)); 2、Response.Cookies[键].Value 值; 3、制作持久Cookie Response.Cookies[键].Expires DateTime.Now.AddDays(7);//设置7天后过期 取值使用Request对象 Request.Cookies[UserName].Value % Page LanguageC# AutoEventWireuptrue CodeFileDefault5.aspx.cs InheritsDefault5 %!DOCTYPE htmlhtml xmlnshttp://www.w3.org/1999/xhtml
