ASP. NET email regular expression not working with hyphen only before the @
原标题:ASP.NET email Regular Expression not working with hyphen just before the @

我有以下伙伴关系。 NET 标志:

<asp:regularexpressionvalidator id="RegularExpressionValidator7"
            runat="server" 
            ControlToValidate="Email1" 
            ErrorMessage="Email not valid" 
            ValidationExpression="w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*">

如你所知,验证表述是视力网络开发商作为违约表示的。 在有人试图进入这一电子邮件地址之前,我一直为我做了大量工作:

有效者说,电子邮件并不有效,而是有效。 我在热邮件.com上进行了核实,你可以在@文号之前制作一个带有星号的电子邮件地址。

我必须改变验证表达方式,以接受这一说法?

最佳回答

@之前添加一个选项(-?)。

ValidationExpresion="w+([-+.]w+)*-?@w+([-.]w+)*.w+([-.]w+)*"
....................change.here....^^

您是否也允许在海芬之前添加<>+? 接着,你也这样说。

ValidationExpresion="w+([-+.]w+)*[-+]?@w+([-.]w+)*.w+([-.]w+)*"
.....................change.here...^^^^^

等等。
