Confusion between pages passing values

When Ispostback=true represents a non-first request * httpcontext.current.request.querystring[] in parentheses is to get the parameter value passed by another page

httpcontext.current.request.form["ID"] The form gets the value according to the name= "id", which is not the id= "id" of the httpcontext.current.request["id", the general version of both.

Essence: ID is name= "id" <form>

<input type= "text" name= "ID" value= "AAAA"/> <

/form>

<input type= "hidden" name= "Hidid" id= "Hidid"/>

Html:

int id = Int. Parse (context. request["Hidid"]?? "0")
