首先，我搜索了此错误，但未发现任何错误。完整的例外：
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是通过/ about URL路径访问的Razor Page，它运行良好。仅当我尝试进入/ home / index或其他mvc视图时，才会发生此错误。
答案 0 :(得分：5)
在您的一个“剃刀视图”中，有一个锚标签看起来像这样：
<a asp-page="About">About</a>
该语法（不带正斜杠/）仅在Razor Page内部起作用。
在“剃刀视图”中，页面名前面应加上正斜杠/，如下所示：
<a asp-page="/About">About</a>
Views目录中。 Pages目录中，并且在文件顶部具有@page指令。答案 1 :(得分：0)
<a class="nav-link" asp-area="Identity" asp-page="/Account/Manage/ChangePassword">
要创建剃刀页面链接，请添加 asp-区域，然后添加 asp-page。
