Check if query string variable not exist ASP.NET

Hi Sir,

HtmlPage.Document.QueryString will give you a dictionary with a list of all query string values.

If the count is 0, there is no key available.

0

if (Request.QueryString["test"] != null)

{

//your code

}

0

Hi Mukesh,

Do it this way

if (Request.QueryString["[VARIABLE]"] != "") {

//put your code here

}

This is the way to check if query string exists or not.

Please mark it as an answer if my post satisfies yours query
