How to determine dns addresses through a proxy?

Question

Domain Name System

Whether it is possible to receive the list of dns proxy without using at the same time the browser (perhaps ie)? Preferably using c#?
As far as I know, when using a proxy, dns addresses also go with it (tested on firefox: settings - additional - network - configure and check the box "send dns requests through proxy ..", if you do not check the box, then by going to whoer we will see dns systems).
I tried to access sites with a webbrowser to determine dns (both with and without a proxy), but for some reason dns addresses were not issued

webBrowser1.Navigate("https://whoer.net");
            webBrowser1.ScriptErrorsSuppressed = true;

Answer 1

"send dns requests through a proxy .." this is apparently a bad translation, because, in fact, no dns request is sent, it's just that in the proxy in the request for a DNS connection, instead of the IP address, the name is left. The client does not receive a response with the server address, the proxy server handles the connection itself.
You can send DNS traffic through a proxy, for example with a configuration like this 3proxy
auth iponly
nscache 65536
nserver 127.0.0.1:5353/tcp
dnspr -i127.0.0.1
flush
allow *
parent 1000 socks ip_of_the_socks port_of_the_socks login password
tcppm -i127.0.0.1 5353 8.8.8.8 53
there will be a DNS resolver on port 53 that redirects DNS queries to Google's DNS through the parent proxy. But it will work slowly, of course.
