How do you make sure there are at least two characters between the @ character abd the . character.

public static bool IsValidEmail(string strEmail)
        {
            bool result = true;

            if (strEmail.Length < 8)
            {
                result = false;
            }
            else if (!strEmail.Contains("@"))
            {
                result = false;
            }
            else if (strEmail.IndexOf("@") < 2)
            {
                result = false;
            }
            else if (!strEmail.Contains("."))
            {
                result = false;
            }
            else if (strEmail.IndexOf(".") < 6)
            {
                result = false;
            }
             else if (strEmail.IndexOf("."))
            {
                result = false;
            }
            else
            {
                result = true;
            }

            return result;
        }
    }
}
