在视图中执行处理程序的子请求时出错 [英] Error executing child request for handler in view

问题描述

我有一个 MVC 4 视图，我在其中呈现以下操作

I have an MVC 4 view where I render the following actions

@{
    Html.RenderAction("Index", "Logo");
    Html.RenderAction("Index", "MainMenu");
}

我的视图中有一个表单，该表单已填写并发布到控制器.在控制器中，我执行一些任务，然后将模型发送回我的视图

I have a form on my view which is filled out and posted to the controller. In the controller I perform some tasks and then send the model back to my view

[HttpPost]
public ActionResult Index(ManageAdministratorModel manageAdministratorModel)
{
     // I save some of the fields to the database here.
     return View(manageAdministratorModel);
}

当我被重定向到视图时，我收到以下错误

When I'm redirected to the view I receive the following error

执行处理程序System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper"的子请求时出错.

Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'.

在这条线上

Html.RenderAction("Index", "Logo");

知道为什么会这样吗?

推荐答案

好的，我找到了问题，希望这对未来的人有所帮助.

Ok I found the problem, hopefully this will help someone in future.

每个局部视图的控制器都包含 [HttpGet] 属性.例如

The controllers for the partial views each contained the [HttpGet] attribute. For example

[HttpGet]
public ActionResult Index()
{
}

我从两个控制器中删除了属性

I remove the attribute from both controllers

public ActionResult Index()
{
}

现在一切正常.
