如何使用aspnet Razor显示弹出消息

Question

I need to validate some fields from a form, I'm not using any front-end language to perform this, I'm getting the information from the ActionResult I need to show some message! 我需要验证表单中的某些字段，我没有使用任何前端语言来执行此操作，而是从ActionResult获取信息，我需要显示一些消息！

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult ResetPassword(string user, string hash)
    {
        string old = Request.Form["oldpassword"];
        string password = Request.Form["password"];
        string repeat = Request.Form["repeatpassword"];


        if(String.IsNullOrEmpty(old) || String.IsNullOrEmpty(password) || String.IsNullOrEmpty(repeat))
        {
            "show a dialog".
        }

</head>
<body>
    @{
        if (ViewBag.ShowDialog != null && ViewBag.ShowDialog == true)
        {
            <script type="text/javascript">
                $(function () {
                    $("#aModal").modal('show');
                })
            </script>
        }
    }
    @using (Html.BeginForm("ResetPassword", "Home"))
    {
        <div>
            <table>
                <tr>
                    <td>@Html.LabelFor(r => r.oldPassword)</td>
                    <td>@Html.TextBoxFor(r => r.oldPassword)</td>
                </tr>
                <tr>
                    <td>@Html.LabelFor(r => r.newPassword)</td>
                    <td>@Html.TextBoxFor(r => r.newPassword)</td>
                </tr>
                <tr>
                    <td>@Html.LabelFor(r => r.repeatNewPassword)</td>
                    <td>@Html.TextBoxFor(r => r.repeatNewPassword)</td>
                </tr>
            </table>
        </div>
        <input type="submit" value="submit" />
    }
    @*modal*@
    <div class="modal fade" id="aModal" tabindex="-1" role="dialog" aria-labelledby="aModalLabel"
         aria-hidden="true">
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-header">
                    <h4 class="modal-title" id="aModalLabel">Warning</h4>
                </div>
                <div class="modal-body">
                    Old Password, New Password, or repeat Password is empty.
                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
                </div>
            </div>
        </div>
    </div>
