您必须包括**

@RenderSection（“精选”，必填项：false）

---

**在_layout.cshtml

的标题部分中，这意味着您已经在masterlayout.cshtml中定义了一个部分，但是您没有在视图中包含该部分的任何内容

如果您的

\u Layout.cshtml

具有以下内容：

@RenderSection("scripts")

然后，使用该布局的所有视图必须包含具有相同名称的

@节

（即使节的内容为空）：

或者，您可以将required设置为false，这样您就不会 需要在每个视图中添加剖面

或者也可以将

@RenderSection

包装在if块中

@if (IsSectionDefined("scripts"))
{
    RenderSection("scripts");
}

此外，您还可以将以下行添加到

\u Layout.cshtml

或

Layout.Mobile.cshtml

：

@RenderSection（“脚本”，必需：false）

---

在视图中，如果使用@section scripts{}或@section styles{}，则必须在布局页面的标题或正文中添加以下代码 @RenderSection（“脚本”，必需：false）

---

@RenderSection（“styles”，required:false）

将

\u Layout.cshtml

文件的布局属性设置为自身时，也会引发此错误。例如，通过

\u ViewStart.cshtml

文件中的以下代码：

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

---

为我工作。我很惊讶：false不是_layout.cshtml的默认设置。

@if (IsSectionDefined("scripts"))
{
    RenderSection("scripts");
}

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