我正在使用 RegularExpressionValidator 来验证特定公司的电子邮件 ID。这个：

ValidationExpression=\\w+([-+.']\\w+)*@ABCCompany.com

仅适用于第一个电子邮件 ID，我需要验证多个电子邮件。我在网上找到了另一个：

ValidationExpression="((\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*)*([;])*)*"

它工作正常，但我必须验证ABCCompany.com. 我也尝试CustomValidator了服务器端验证，它的工作代码很明智，但它没有显示错误消息。

谁能帮我解决我的问题。

我的 HTML 代码：

<

服务器端验证代码：

    protected void cvtbProduct_Email_OnServerValidate(object sender, ServerValidateEventArgs args)
    {
        bool valid;

        var email = new string[100];

        var emailList = (TextBox) RadGrid1.MasterTableView.GetInsertItem().FindControl("Product_Email");

        if (emailList.Text != "")
        {
            if (emailList.Text.Contains(";"))

                email = emailList.Text.Split(';');

            else

                email[0] = emailList.Text;

            for (var i = 0; i < email.Length; i++)
            {
                if (email[i] != null)
                {
                    valid = Regex.IsMatch(email[i], "\\w+([-+.']\\w+)*@ABCCompany.com");

                    if (!valid)
                    {
                        args.IsValid = false;
                    }

                    else

                        args.IsValid = true;
                }
            }
        }
    }

    protected void cvtbProduct_Email_OnServerValidate(object sender, ServerValidateEventArgs args)

        var emailList = (TextBox) RadGrid1.MasterTableView.GetInsertItem().FindControl("Product_Email");

        //you don't need to check if it has the seperator in it
        var emails = emailList.Text.Split(';');

        foreach (var email in emails)

            var valid = Regex.IsMatch(email, @"\w+([-+.']\w+)*@ABCCompany\.com");
