在 Razor (chtml) 中呈现动态视图，如何在 asp.net core 3.0 中将 FileProvider 添加到 razor？

Question

我正在从 asp-net core 2.2 迁移到 asp-net core 3.0，我使用这个块来定义我的文件 Class Provider，如你所知这是用于创建动态剃刀视图（动态 cshtml），我的问题是该段不起作用。

我实现了经典：

services.Configure<RazorViewEngineOptions>(opts =>
                opts.FileProviders.Add( 
                    new MyCostumizedFileProvider()
                )
            );

其中：

MyCostumizedFileProvider : 是文件提供程序的实现。
RazorViewEngineOptions : 是 aspnet core 2.0 中使用的 Razor 运行时编译器的处理程序。

在asp-net core中我查看过

例如：

services.Configure<MvcRazorRuntimeCompilationOptions>(options => {
    options.FileProviders.Clear();
    options.FileProviders.Add(new MyCostumizedFileProvider());
});

或

  services.Configure<MvcRazorRuntimeCompilationOptions>(options => {
   options.FileProviders.Add(new MyCostumizedFileProvider());
  });

错误总是：

你有解决办法吗？或者你知道其他注入 FileProvider 的方法吗？

Answer 1

DavidG 为我们提供了解决方案：（我已经测试过并且有效）。

解决方法是：

services.AddControllersWithViews().AddRazorRuntimeCompilation(
    options => options.FileProviders.Add(new PhysicalFileProvider(appDirectory)));

在这种情况下：

services.AddControllersWithViews().AddRazorRuntimeCompilation(
    options => options.FileProviders.Add(new MyCostumizedFileProvider()));

Answer 2

对于ASP.NET MVC Core 3，这是添加文件提供程序的方法：

services.AddControllersWithViews()
    .AddRazorRuntimeCompilation(options => options.FileProviders.Add(
        new PhysicalFileProvider(appDirectory)));
