问题描述

首先，我搜索了这个错误，但什么也没有找到。完全例外：

    System.InvalidOperationException: The relative page path 'About' can only be used while executing a Razor Page. Specify a root relative path with a leading '/' to generate a URL outside of a Razor Page.

About is Razor Page通过/About url路径访问，运行良好。仅当我尝试打开/home/index或其他MVC视图时才会出现此错误。

推荐答案

问题

在您的一个Razor视图中，有一个如下所示的锚标记：

<a asp-page="About">About</a>

该语法(不带正斜杠/)只能在Razor Page中工作。

解决方案

在Razor视图中，在页面名称前面加上一个正斜杠/，如下所示：

<a asp-page="/About">About</a>

区分Razor视图和Razor页面

• 剃须刀视图通常位于Views目录中。
• 剃刀页通常位于Pages目录中，并且文件顶部有@page指令。
