Replace item in querystring

Question

I have a URL that also might have a query string part, the query string might be empty or have multiple items.

I want to replace one of the items in the query string

Answer 1

I agree with Cerebrus. Sticking to the KISS principle, you have the querystring,

string querystring = myURI.Query; 

you know what you are looking for and what you want to replace it with.

So use something like this:-

if (querystring == "") 
  myURI.Query += "?" + replacestring; 
else 
  querystring.replace (searchstring, replacestring); // not too sure of syntax !!
