asp.net-mvc – 未找到部分视图或视图引擎不支持搜索的位置

public MyController:Controller
{
 public ActionResult Index()
  {
     return View();
  }
 [ChildActionOnly]
 public ActionResult MyPartialViewAction()
 {
    return PartialView("~/Views/Shared/MyCustomFolder/_MyPartialView",PartialViewModel);
 } 
}

我的索引视图具有以下代码：

@HTML.Action("MyPartialViewAction")

当我运行Web应用程序，我得到HttpException与InnerExceptionMessage为：

InnerException {“The partial view ‘~/Views/Shared/MyCustomFolder/_MyPartialView’ was not found or no view engine supports the searched locations. The following locations were searched:rn~~/Views/Shared/MyCustomFolder/_MyPartialView”} System.Exception {System.InvalidOperationException}

我到现在为止已经尝试过

尝试将_MyPartialView从?/ Views / Shared / MyCustomFolder移动到?/ Views / Shared /和?/ Views / MyControllerFolder，但仍然存在错误
试着将我的索引查看代码改成@ HTML.RenderAction()，但没有运气。

任何输入，我错了哪里？

谢谢
