如何在Controller中构建Razor语法并在视图中呈现它

Question

我有一个Ajax请求在我的控制器中建立一个表。 我试图在控制器中使用@Html.DropDownListFor razor @Html Helpers创建下拉列表，然后将其返回到我的视图。 该视图将@Html.DropDownListFor呈现为原始语法。 当它在控制器中构建然后传递到我的视图时，似乎完全失去了剃刀的作用。

有没有一种方法可以构建/构造razor语法服务器端，并使其在视图中成功呈现？

控制者

public ActionResult Index(string siteSelected, string pcmSelected, string busGrpSelected, string monthSelected, string ssoSelected){

var associateResults = _appResult.TOSAdjustmentResult(siteSelected, busGrpSelected, pcmSelected, b.getMonth(monthSelected, true));

foreach (var item in associateAdjusmentResults.view_tos_with_adjustment_final)
                {

                    t1 += "<td>" + item.DIRECTION + "</td>";
                    t1 += "<td>" + item.CALLS + "</td>";
                    t1 += "<td>" + item.TALK + "</td>";
                    t1 += "<td>" + item.HOLD + "</td>";
                    t1 += "<td>@Html.DropDownListFor(model => model.site, new SelectList(Model.site), '--Site--', new { @id = 'siteId' })</td>";
                    t1 += "</tr>";
                }

                return Content(t1);
}

视图

<table class="table-condensed table-hover table-responsive table-bordered two small header" id="adjustmentTable">
    <tr>
        <td>
            Direction
        </td>
        <td>
            Calls
        </td>
        <td>
            Talk
        </td>
        <td>
            Hold
        </td>
        <td>
            DropDownList
        </td>
    </tr>
</table>

jQuery /阿贾克斯

$(".clickableRow").on("click", ".clickableRow", function () {
    //Getting SSO from search table
    var sso = this.cells[1];

    $("#adjustmentTable").find("tr:gt(0)").remove();
    $.ajax({
        url: "/TOSAdjustment/Index",
        type: "POST",
        data: {
            ssoSelected: $(sso).text(),
            monthSelected: $('input[name=monthOptions]:checked').val()
        }
    })
    .done(function (res) {
        $("#msg").html("Response from search received");
        $("#adjustmentTable").append(res);
    }).fail(function (x, a, e) {
        alert(e);
    });
});
