c# - Postback page on query string -

-

This question has been repeated, when I am getting value in my query string, I have to post page back . 

  If I want to post back here (request.jquery string ["hotelid"] = = null) // {  
 I How can I post back the page?   
 
 
 You can use it:  
  if (request. QueryString ["HotelID"]! = Null) {page_load (sender, e); }   
 or this:  
  if (request .QueryString ["HotelID"] = null) {Response.Redirect (Page.AppRelativeVirtualPath.ToString () ); }   
 Hope this helps :)
