c# - 无效操作异常 : The view 'ViewName' was not found after adding route

Question

为我的网络应用程序设置分页后，我决定更改网址，使其看起来更好。一切都很完美，直到我决定添加一条路线，在更改页面后出现以下错误

"InvalidOperationException: The view 'Books' was not found. The following locations were searched: /Views/Shared/Books.cshtml"

以及路由

routes.MapRoute
(
     name: "pagination",
     template: "Books/Page/{page}",
     defaults: new {Controller = "Core", action = "Books"}
);

似乎没有任何拼写错误，我已经检查了三次 Controller 和 View 是否位于正确的路径中并且具有正确的方法。 这里可能有什么问题？它没有在正确的文件夹中搜索 View

Answer 1

您可以将 page 设置为可选并重试吗？ 如果 Books 操作方法中的页面为 null，则您可以在该方法中引发自定义错误。

app.UseMvc(routes =>
{
    routes.MapRoute(
        name: "pagination",
        template: "Books/Page/{page?}"
        defaults: new { controller = "Core", action = "Books"});
});

或者使用属性路由。

public class CoreController : Controller
{
   [HttpGet("/Books/Page/{page?}")]
   public IActionResult Books(int? page) { ... }
}
