Or Right(name, 1) = "." Then IsValidEmail = False:Exit Function Next If InStr(names(1), ".") <= 0 Then IsValidEmail = False:Exit Function I = Len(names(1)) - InStrRev(names(1), ".") If I <> 2 And I <> 3 Then IsValidEmail = False:Exit Function If InStr(Email, "..") > 0 Then IsValidEmail = False End Function其它语言可以参考：邮箱地址正则表达式验证代码合集中文源码网特别版
