How to add query string to httpwebrequest

Question

I want to add some querystrings to httpwebrequest, however I cannot find any property? I remembered there is a QueryString dictionary which I can use before.

I don't get you. Just put parameter names and values in the url and execute the request then the page/response will be able to access to the querystring dictionary and consume it. — Davide Piras

The best way to add a query string is as follows:

var targetUri = new Uri("http://www.example.org?queryString=a&b=c");
var webRequest = (HttpWebRequest)WebRequest.Create(targetUri);

var webRequestResponse = webRequest.GetResponse();

Remember: If you're using user input to construct the Uri, ensure that you validate it, escape it and don't trust it.

but what if I want to add query string later on..?? e.g HttpWebRequestObject is already initialized and I want to add something to Uri for query string @Rob don't forget to tag in comment response

@ShashwatTripathi, as the RequestUri property is read-only and the Query property on Request.Uri is as well, I suspect the answer is that you can't.

I could't find a way of extending an existing Request so ended up having to re-create the request from scratch if I wanted to append to it.
