Answer 1

You can use Regex for email validation.

First add following using statement

using System.Text.RegularExpressions;

And after that use following helper method for validation:

Regex EmailRegex = new Regex (@"^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$");
public bool ValidateEmail(string email)
{
    if (string.IsNullOrWhiteSpace(email))
        return false;

    return EmailRegex.IsMatch(email);
}

Option 2:

Xamarin.Android has a helper method for email validation you also use that:

Android.Util.Patterns.EmailAddress.Matcher(email).Matches();
