Answer 2

protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)
    {
        string userid=args.Value;
        if (count == 0)
        {
            //则通过验证,不显示CustomValidator控件的错误信息
            args.IsValid = true;
        }
        else
        {
            //否则不能通过验证,显示错误信息,用户以存在
            args.IsValid = false;
