response如何传递数据
login.htm 
  <body>  
  <form   method= "post "   action= "Default.aspx? "   >  
              <input   id= "txtUserName "   type= "text "      />  <br   />  
              <input   id= "txtUserPwd "   type= "text "   />  <br   />  
              <input   id= "Submit1 "   type= "submit "   value= "submit "   />  
     </form>  
  </body>  
 default.aspx 
    protected   void   Page_Load(object   sender,   EventArgs   e) 
             { 
                         if   (Request[ "txtUserName "]   !=   null   &&   Request[ "txtUserPwd "]   !=   null) 
                      { 
                                  string   userName   =   Request[ "txtUserName "].ToString(); 
                                  string   userPwd   =   Request[ "txtUserPwd "].ToString(); 
                                  Response.Write( "登录的用户名为 "   +   userName   +    "登录的密码为 "   +   userPwd); 
                         }                     
             }     
 哪里错了?为什么运行的时候,default.aspx里一片空白呀?
