form之get/post

.net2.0  VS2005

一、login.aspx :  <FORM action="main.aspx" method="post">

         main.aspx:   string userName=Request["userName"].ToString();

                               string userPwd=Request["userPwd"].ToString();

                              -------------------------------------------------------------------------

                               string userName=Request.Form.Get("userName").ToString();

                               string userPwd=Request.Form.Get("userPwd").ToString();

二、login.aspx:<FORM action="main.aspx" method="get">

        main.aspx: string userName=Request.QueryString["userName"].ToString();

                            string userPwd=Request.QueryString["userPwd"].ToString();

     不同之处：使用get方法则会显示为main.aspx?userName=xxxx&userPwd=xxxx;

                           使用post方法则作为一个form传递
