Answer 1

.NET 可以为您完成:

  bool IsValidEmail(string eMail)
  {
     bool Result = false;

     try
     {
        var eMailValidator = new System.Net.Mail.MailAddress(eMail);

        Result = (eMail.LastIndexOf(".") > eMail.LastIndexOf("@"));
     }
     catch
     {
        Result = false;
     };

     return Result;
  }
