ASP.NET MVC5从布局访问ViewBag？

Question

我正在尝试将动态数据从我的控制器传递到我的视图和布局.我目前正在使用ViewBag将数据从Controller传递到视图,该视图工作正常.我无法从布局中访问ViewBag.有没有办法做到这一点？

我正在使用ASP.NET W/MVC5(C#).

编辑:更新了W /代码:

//layout.cshtml
@ViewBag.username

产生此错误:

Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS0103: The name 'ViewBag' does not exist in the current context

我建议你有一个布局使用的动作方法,它传递你需要的数据.例如

public class ControllerName : Controller
{
    public ActionMethod GetData()
    {
       return Content("Some data"); // Of whatever you need to return.
    }
}

然后在布局和视图中,您可以调用

@Html.Action("GetData", "ControllerName")
