復(fù)制代碼 代碼如下: '******************************************** '函數(shù)名：IsValidEmail '作 用：檢查Email地址合法性 '參 數(shù)：email ----要檢查的Email地址 '返回值：True ----Email地址合法 ' False ----Email地址不合法 '******************************************** Public Function IsValidEmail(Email) Dim names, name, I, c IsValidEmail = True names = Split(Email, "@") If UBound(names) <> 1 Then IsValidEmail = False: Exit Function For Each name In names If Len(name) <= 0 Then IsValidEmail = False:Exit Function For I = 1 To Len(name) c = LCase(Mid(name, I, 1)) If InStr("abcdefghijklmnopqrstuvwxyz_-.", c) <= 0 And Not IsNumeric(c) Then IsValidEmail = False:Exit Function Next If Left(name, 1) = "." 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
