Steamwork.NET get userID or email by name

Hi, I’d need to know userID or email of a steam’s user, I’m using Steamwork.NET

I doubt very much you can get the email of the user as that’s likely to be private information. You can get the userID/name though using this:

Steamworks.CSteamID SteamID = SteamUser.GetSteamID();
string SteamName = SteamFriends.GetPersonaName();
