asp.net-mvc – 未找到部分视图“First.cshtml”或视图引擎不支持搜索的位置

我试图在点击时调用div中的局部视图.我写过：

@Ajax.ActionLink("Second","Second",new AjaxOptions()
{
    HttpMethod = "GET",UpdateTargetId = "partials",InsertionMode = InsertionMode.Replace
})

<div id="partials">
</div>

<script src="https://code.jquery.com/jquery-2.1.3.min.js" type="text/javascript"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.9/jquery.validate.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.9/additional-methods.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/mvc/5.2/jquery.validate.unobtrusive.min.js" type="text/javascript"></script>

在我的Index.cshtml中.我的控制器看起来像这样：

public ActionResult Index()
        {
            return View();
        }

        public PartialViewResult Second()
        {

            return PartialView("Second.cshtml");
        }

但我的错误说我的部分视图无法找到：

~/Views/switchPartial/Second.cshtml.aspx
~/Views/switchPartial/Second.cshtml.ascx
~/Views/Shared/Second.cshtml.aspx
~/Views/Shared/Second.cshtml.ascx
~/Views/switchPartial/Second.cshtml.cshtml
~/Views/switchPartial/Second.cshtml.vbhtml
~/Views/Shared/Second.cshtml.cshtml
~/Views/Shared/Second.cshtml.vbhtml

但我在switchPartial文件夹中有它.

如果我在我的div中写@ Html.Partial(“Second”)它会正确呈现我的局部视图.

我做错了什么？

解决方法

无需在部分名称的末尾包含文件扩展名.尝试：

return PartialView("Second");

通过不包括文件扩展名,每个注册的ViewEngines都有机会解析所请求的视图(在Second.cshtml,Second.vbhtml或Second.aspx中).
