我正在尝试使用创建用户向导创建一个用户。对于电子邮件验证，我使用正则表达式控件。我为电子邮件文本框的id指定了ControlToValidate属性。当我给出错误的电子邮件Id并点击创建用户时，它会显示我在<asp:RegularExpressionValidator>中配置的错误消息，但它会进入下一步，并说用户创建成功当电子邮件格式错误时，如何停止注册用户。我正在尝试修改类似于此的CreatingUser事件

protected void CreateUserWizard1_CreatingUser(object sender, LoginCancelEventArgs e)
        {
            bool allfieldsstatus = false;
            RegularExpressionValidator emailvalidator = (RegularExpressionValidator)CreateUserWizardStep1.ContentTemplateContainer.FindControl("emailvalidator");
            if (!emailvalidator.Visible)
            {
                allfieldsstatus = true;
            }
            if (allfieldsstatus)
            {
                e.Cancel = false;
            }
            else
            {
                e.Cancel = true;
            }
        }

但这是行不通的。可见性属性根本没有显示。我在if条件下以另一种方式尝试if(!emailvalidator.ErrorMessage.length!=0) { allfieldstatus = true; }这也不起作用。因为ErrorMessage属性总是存在于<asp:RegularExpressionValidator >的配置中解决方案是什么？

通常，您应该检查验证是否通过了单个验证程序控件或页面本身的IsValid属性：

if (!emailvalidator.IsValid) {
    e.Cancel = true;
}

或

if (!Page.IsValid) {
    e.Cancel = true;
}

对于向导，您可以在NextButtonClick和FinishButtonClick事件处理程序中执行此检查。

如果你认为这是RegExp的问题，试试这个：

/^((([a-z]|'d|[!#'$%&''*'+'-'/='?'^_`{'|}~]|['u00A0-'uD7FF'uF900-'uFDCF'uFDF0-'uFFEF])+('.([a-z]|'d|[!#'$%&''*'+'-'/='?'^_`{'|}~]|['u00A0-'uD7FF'uF900-'uFDCF'uFDF0-'uFFEF])+)*)|(('x22)(((('x20|'x09)*('x0d'x0a))?('x20|'x09)+)?((['x01-'x08'x0b'x0c'x0e-'x1f'x7f]|'x21|['x23-'x5b]|['x5d-'x7e]|['u00A0-'uD7FF'uF900-'uFDCF'uFDF0-'uFFEF])|(''(['x01-'x09'x0b'x0c'x0d-'x7f]|['u00A0-'uD7FF'uF900-'uFDCF'uFDF0-'uFFEF]))))*((('x20|'x09)*('x0d'x0a))?('x20|'x09)+)?('x22)))@((([a-z]|'d|['u00A0-'uD7FF'uF900-'uFDCF'uFDF0-'uFFEF])|(([a-z]|'d|['u00A0-'uD7FF'uF900-'uFDCF'uFDF0-'uFFEF])([a-z]|'d|-|'.|_|~|['u00A0-'uD7FF'uF900-'uFDCF'uFDF0-'uFFEF])*([a-z]|'d|['u00A0-'uD7FF'uF900-'uFDCF'uFDF0-'uFFEF])))'.)+(([a-z]|['u00A0-'uD7FF'uF900-'uFDCF'uFDF0-'uFFEF])|(([a-z]|['u00A0-'uD7FF'uF900-'uFDCF'uFDF0-'uFFEF])([a-z]|'d|-|'.|_|~|['u00A0-'uD7FF'uF900-'uFDCF'uFDF0-'uFFEF])*([a-z]|['u00A0-'uD7FF'uF900-'uFDCF'uFDF0-'uFFEF])))'.?$/i
