If you're going to be manipulating email addresses you're best off using the MailAddress class in the System.Net.Mail namespace:

MailAddress addr = new MailAddress("mynameismine@hotmail.com");
string username = addr.User;
string domain = addr.Host;

username is the part before the '@' symbol and domain is the part after.

var newString = emailString.Split('@').First();

split the string up by @, grab the first item.

This wouldn't work if the name contained an '@' symbol. – Calum Sep 30 '15 at 21:25
@Calum if the name contained `@` then it shouldn't be there in the first place. – DPac Sep 30 '15 at 21:27

@Calum doubt that would be a valid email address then – Jonesopolis Sep 30 '15 at 21:27

@Calum radical. you could always grab everything except the last, and concat them together. However I doubt this is a problem here. – Jonesopolis Sep 30 '15 at 21:36

@Calum I stand corrected. I did not know that such oblivious address (e.g. "this$is#complete.ly@valid-%email"@example.com) is valid. – DPac Sep 30 '15 at 21:37

using System.Net.Mail;

MailAddress address = new MailAddress("mynameismine@hotmail.com");
string username = address.User;

Just a class specially for these purposes.
