在 Razor (chtml) 中渲染动态视图，如何在 asp.net core 3.0 中将 FileProvider 添加到 razor? [英] Rendering dynamics views in Razor (chtml), How to add a FileProvider to razor in asp.net core 3.0?

问题描述

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类提供程序，正如你所知，它用于创建动态剃刀视图(动态 cshtml)，我的问题是该段不起作用.

I am migrating from asp-net core 2.2 to asp-net core 3.0, I was using this block to define my File Class Provider, as you know this is used to create dynamic razor views (dynamic cshtml), my problem is that segment does not work.

我已经实现了经典:

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

地点:

1. MyCostumizedFileProvider:是文件提供程序的实现.

1. MyCostumizedFileProvider : is the Implementation of File Provider.

RazorViewEngineOptions :是在 aspnet core 2.0 中使用的 Razor 运行时编译器的处理程序.

RazorViewEngineOptions : is the handler of the Razor runtime compilator used in aspnet core 2.0.

在asp-net core中我已经检查过

In asp-net core I have checked

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:

你有线索吗，解决方案?或者你知道其他注入 FileProviders 的方法吗?

Do you have a clue, solution? or Do you know other way to inject FileProviders?

推荐答案

对于 ASP.NET MVC Core 3，这是添加文件提供程序的方法:

For ASP.NET MVC Core 3, this is the way to add a file provider:

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