c# - 路径中包含非法字符。与IEnumerable一起使用跳过和接受时出错

嗨，我的 Controller 中有以下操作

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index()
{
    IEnumerable<SurveyResult> myresult = filterData();
    totalCount = myresult.Count<SurveyResult>();
    ViewBag.totalCount = totalCount;
    //myresult = myresult.Skip<SurveyResult>(100 * pageIndex).Take<SurveyResult>(100);
    return View(myresult);
}

这是我的看法

@model IEnumerable<SurveyResult>
@{
    ViewBag.Title = "Survey Results";
}
@using (Html.BeginForm())
{

    <table class="std-tbl">
        <thead>
            <tr>
                <th>
                    DEL
                </th>
                ...

                <th>
                </th>
            </tr>
        </thead>
        @Html.DisplayFor(x => x, new { pageIndex = ViewBag.index })
    </table>
}

我对SurveyResult有部分看法，但由于我认为它不相关，所以不包括在内。这是我的问题。上面的代码工作正常，但是只要我取消注释以下行

myresult = myresult.Skip<SurveyResult>(100 * pageIndex).Take<SurveyResult>(100);

我收到“路径中的非法字符。”我认为它可以为SurveyResult找到partialView。我不明白为什么在注释上面的行时可以找到它，但是在未注释时却找不到呢？谢谢你。

这是我的堆栈跟踪

最佳答案

DisplayFor正在寻找以EF生成的实现类的名称命名的 View ，该实现类包含非法字符。

尝试在 Controller 中调用.ToList()。
