The difference between ASP. NET Request, Request.Form, Request.QueryString

Request.Form: Gets the data submitted by post (receives the data submitted by the Form);

Request.QueryString: Gets the Address bar parameter (data submitted in get mode)

Request: Contains both of the above methods (the first to get the data submitted by get mode), it will be in QueryString, Form, servervariable search again.

And sometimes they get different results. If you only need one of the data in the Form, but you use the request instead of the Request.Form, then the program will be searched again in querystring and ServerVariable. If you have the same name in your querystring or servervariable, you will not get the value you originally wanted.
