Question

这必须是基本的但我想在FormCollection中添加一个HTML控件，你在控件的name属性上设置一个值。但这似乎没有任何影响。尝试过两个控件 - 下面的代码中的txtRating和FileUpload（都在底部附近）。我究竟做错了什么？正确调用该方法并将Html帮助程序控件放在FormCollection中，但不是我尝试添加的控件。缺少什么？

@using (Html.BeginForm("SaveReview", "Content", FormMethod.Post, new { enctype = "multipart/form-    data", id = "photoform" }))
{
<fieldset>
    @Html.Hidden("ReviewID", Model.ReviewID, new { @id = "hidReviewID" })
    @Html.Hidden("RestaurantID", null, new { @id = "hidRestaurantID" })
    @Html.Hidden("IsNewReview", Model.IsNewReview)
    @Html.HiddenFor(m => m.UserID, new { @id = "hidUserID" })
    @if (Model.IsInEditMode)
    {
        <div class="bodyc">
            <div id="reviewsbody3" class="sectionbody1all">
                <div class="reviewtxtrestaurant">
                    @Html.TextBoxFor(m => m.RestaurantNamePlusVicinity, htmlAttributes: new { id = "txtSearch", placeholder = "Search restaurant name", @style = "width:99%; margin:5px auto;display:block;" })
                </div>
                Visit Date: @Html.TextBoxFor(m => m.VisitDate, "{0:dd-MM-yyyy}", htmlAttributes: new { id = "txtVisitDate", @readonly = "readonly" })
                Meal Type: @Html.DropDownListFor(m => m.MealTypeName, new SelectList(Model.MealTypes, "Value", "Text", "Dinner"))
            </div>
        </div>
    }
    else
    {
        <div class="bodyc">
            <div id="reviewsbody3" class="sectionbody1all">
                <div class="reviewtxtrestaurant">@Html.DisplayFor(m => m.RestaurantNamePlusVicinity, new { @style = "width:98%; margin:0px auto;display:block;" })</div>
                Visit Date: @Html.DisplayFor(m => m.VisitDate, "{0:dd-MM-yyyy}")

    </div>
</fieldset>
}

编辑：

方法如下：

public ActionResult SaveReview(FormCollection f)
{
}

并通过普通按钮发布，点击事件通过JQuery设置：

            $('#btnSave').click(function () {
                $('#photoform').submit();
            });

以下是生成的HTML：

<form action="/Content/SaveReview" enctype="multipart/form-data" id="photoform" method="post">

        <input data-val="true" data-val-required="The ReviewID field is required." id="hidReviewID" name="ReviewID" type="hidden" value="e0ee6f58-a8f0-4ff8-b6fc-3fd2ed591567" />

            </div>
        </div>
    </fieldset>
</form>

注释
RestaurantNamePlusVicinity
VisitDate
MealTypeName
注释

谢谢，罗布

Answer 1

txtRating - 是一个标签。使用int属性（键入＆＃39;隐藏＆＃39;或＆＃39;文本＆＃39;）和value属性。
uploadFile - 输入类型＆＃39; file＆＃39;。在您的操作方法中检查Request.Files集合。
