问题 Does anyone know what the side effects are of having a webrequest.proxy = null in a HttpWebRequest?

Does the webrequest in both cases still work if the user's network requires proxy settings? So , what is the correct approach and any known issues/side effects when a proxy is needed? About the deprecated

If it is not possible

问题 I'm interested in interfacing with Discord using the Discord API. I would describe their documentation as "sparse," but maybe I'm just not looking in the right places. Most of my information comes from this page: https://discordapp.com/developers/docs/topics/oauth2 I've already set up my Discord guild and application (and even a bot, which may be unnecessary).
