Hi,

I have a question related to Request.QueryString:

I obtain a category name from URL with following format (i replaced URL name with codeproject.com for no advertising).

codeproject.com/default.aspx?category =asp.net

According to the incoming URL category name "asp.net" for example. I query SQL behind the code site.

My question is if i want to query 2 string from incoming URL; how can i do.

I mean:
- where to add second category name at codeproject.com/default.aspx?category =asp.net
- how to handle second category2 name with Request.QueryString at code site. I handle category string with following code:

C#

string catagory1="empty";
if(Request.QueryString["category"] !=null)
  {
     catagory1=Request.QueryString["catagory"].ToString();

  }

Kind Regards,

Solution 1

To put multiple parameters into a query string, use & to separate them:

For example

example.com/default.asps?animal=tiger&fruit=apple

To extract them, use

string myAnimal = Request.QueryString("animal")
string myFruit = Request.QueryString("fruit")

Actually here are two ways you can do that.

1. You can build a link with many variables like:
www.whatever.com/default.aspx?category1=A&category2=B&category3=C and so on

2. You can program your personal logic in one category name:
www.whatever.com/default.aspx?category=A|B|C
and after when you get a category value just parse it.

I hope it helps.

yes it is a good idea.

You mean at code side to parse with recognizing layers with "|" which.

For example:
section menus link will be like:
database sql\ codeproject.com/default.aspx?catagory=1|sql|3|4|5
database sql\mssql\ codeproject.com/default.aspx?catagory=1|2|mssql|4|5
database sql\oracle\ codeproject.com/default.aspx?catagory=1|2|oracle|4|5

if i understand correct.

thank you fupslot
