在MVC剃刀，你是怎么做到以下子布局定义的RenderSection？ [英] In MVC Razor, how do you do a RenderSection defined below a sub-layout?
问题描述
我有一个顶级_Layout.cshtml，看起来是这样的：
I have a top-level _Layout.cshtml that looks something like this:
<html>
<head>
@RenderSection("Header", required: false)
</head>
<body>
@RenderSection("LeftPane", required: false)
@RenderSection("RightPane", required: false)
@RenderBody()
</body>
</html>
然后我有两个子布局。一个定义只是LeftPane部分，其他的定义了一个LeftPane和RightPane。这些子布局称为_LeftPane.cshtml和_LeftPlusRightPane.cshtml，他们有布局设置为_Layout.cshtml。
Then I have two "sub-layouts." One defines just the LeftPane section, the other defines both a LeftPane and a RightPane. These sub-layouts are called _LeftPane.cshtml and _LeftPlusRightPane.cshtml, and they have Layout set to "_Layout.cshtml."
然后在每个视图.cshtml文件，我的布局设置为_LeftPane.cshtml或_LeftPlusRightPane.cshtml，取决于我想显示在页面上。
Then in each View .cshtml file, I set the Layout to either _LeftPane.cshtml or _LeftPlusRightPane.cshtml, depending on what I want to show up on the page.
这一切工作正常。问题是我在℃加入新的头部，头部＆gt;该文件的部分。此部分未在子布局中定义，而是在实际的观。当我尝试查看的东西就这样，我得到的错误：
That all works fine. The problem is with the new "Header" section I've added in the <head> portion of the document. This section is not defined in the sub-layouts, but rather in the actual Views. When I try to view something this way, I get the error:
下列路段已确定，但尚未呈现为页面布局〜/查看/共享/ _LeftPlusRightPane.cshtml：头
我不希望呈现在sublayouts页眉部分，我想渲染它在_Layout.cshtml文件。我如何通过从低层次的视图定义页眉部分，通过子布局，到顶部_layout？
I don't want to render the Header section in the sublayouts, I want to render it up in the _Layout.cshtml file. How do I "pass through" the defined Header section from the low level view, through the sub-layouts, up to the top _Layout?
推荐答案
您可以嵌套布局。所以_Layout2有布局=_Layout.cshtml;
You can nest layouts. So _Layout2 has Layout = "_Layout.cshtml";
您也可以使用_ViewStart文件每个视图子文件夹指定该子文件夹不同的默认布局。
You can also use _ViewStart files in each of your View subfolders to specify a different default layout for that subfolder.
要穿越一节，你只是做这样的事情：
To "pass through" the section, you just do something like this:
@section Header {@RenderSection("Header", false)}
这允许您通过内容链。
