您可以把 _ViewStart.cshtml 的之内的文件/查看/公这将覆盖默认一个在 /浏览次数文件夹，并指定所需的布局文件夹：

You could put a _ViewStart.cshtml file inside the /Views/Public folder which would override the default one in the /Views folder and specify the desired layout:

@{
    Layout = "~/Views/Shared/_PublicLayout.cshtml";
}

打个比方，你可以把另一个 _ViewStart.cshtml 文件中的内/查看/员工文件夹：

@{
    Layout = "~/Views/Shared/_StaffLayout.cshtml";
}

您也可以指定要使用的布局返回控制器动作内部的视图时，但这是每行动：

You could also specify which layout should be used when returning a view inside a controller action but that's per action:

return View("Index", "~/Views/Shared/_StaffLayout.cshtml", someViewModel);

另一种可能是一个自定义操作过滤器将覆盖布局。正如你可以看到很多的可能性，实现这一目标。由你来选择哪一个最适合你的方案。

Yet another possibility is a custom action filter which would override the layout. As you can see many possibilities to achieve this. Up to you to choose which one fits best in your scenario.

更新：

由于在评论部分要求这里的一个动作过滤器，它会选择一个母版页的例子：

As requested in the comments section here's an example of an action filter which would choose a master page:

public class LayoutInjecterAttribute : ActionFilterAttribute
{
    private readonly string _masterName;
    public LayoutInjecterAttribute(string masterName)
    {
        _masterName = masterName;
    }

    public override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        base.OnActionExecuted(filterContext);
        var result = filterContext.Result as ViewResult;
        if (result != null)
        {
            result.MasterName = _masterName;
        }
    }
}

再装饰一个控制器或与该自定义属性指定你想要的布局动作：

and then decorate a controller or an action with this custom attribute specifying the layout you want:

[LayoutInjecter("_PublicLayout")]
public ActionResult Index()
{
    return View();
}
