how to set up request body with httpWebRequest

Question

I want using httpWebRequest to "POST" data to a website. So i used firebug analyzing what really send to server. First step, i use browser to browsing www.mytargetURL.net, second, turn on firebug, after that, i fill all form data and click the submit button (it's mean POST data to the server). So, I watching firebug and there was a lot of Parameters in request body part. Something like:

param1=
param2=
param3=default_value1
param4=default_value2
param5=value_I_set_byhand1
param6=value_I_set_byhand2

The question is: I should set up the request body of httpWebRequest obj with all the parameters i saw in firebug parameter table (it's mean all 6 parameters) or just parameters which has value (parameter 3-6) or just parameters i have filled in the submit form(just param5 and param6)?

Thanks you for all supports

You create the HttpWebRequest object, get the request stream, and write your parameters to it. The example at HttpRequest.GetRequestStream should point you in the right direction.
