Question

我发现了一些关于此错误的帖子，但不适合我的问题。我在DataGrid中有一个名为Views/Shared/的视图。此视图只是从模型中呈现一个表，并且意图使用Html.RenderAction()呈现为部分视图。我在名为Dynamic的视图中使用了它。

<h2>Dynamic</h2>

@{
    Html.RenderAction("DataGrid", "Orders", new {gridName = "grid_order"});
};

我创建了抽象的BaseController，它包含了我的DataGrid视图的Get方法。

public abstract class BaseController : Controller
{
    ...

    public async Task<PartialViewResult> DataGrid(string gridName)
    {
        var model = /* get data from service */

        return PartialView("/Views/Shared/DataGrid.cshtml", model);
    }
}

当我在Dynamic.cshtml上触发url https://localhost:44300/Orders/Dynamic Html.RenderAction（...）并调用我的BaseController上的get方法时。执行DataGrid.cshtml中的代码后（因为我对它进行了调试）我得到了这个错误：

我忘记了什么吗？

Html.RenderAction（） - 执行处理程序
