    @using (Html.BeginForm()) {

        @Html.ValidationSummary(true)

        <fieldset>

            <legend>MsgModel</legend>

            <div class="editor-label">

                @Html.LabelFor(model => model.Title)

            </div>

            用户名：@Html.DropDownList("ddlStaff_id", (SelectList)ViewBag.list, "请选择")

            <p>

                <input type="submit" value="添加留言" />

    }

    <div>

        @Html.ActionLink("Back to List", "Index")

运行效果如下：
<form action="/Msg/AddMsg" method="post">

<p>

         <input type="submit" value="添加留言" />

         <span class="field-validation-valid" data-valmsg-for="addError" data-valmsg-replace="true"></span>

</p>

</form>

        <script type="text/javascript">

            if (!confirm('添加成功，是否继续添加呢？')) {

               window.location.href="Index";

            }

        </script>

<a href="/Msg">Back to List</a>
