为每个请求添加唯一的自定义单例

Question

我一直在努力找出asp网络核心附带的依赖关系模式。这是我要实现的目标。

_ViewImports.cshtml

...    
@inject AdminBuilder AdminBuilder
...

Startup.cs

public void ConfigureServices(IServiceCollection services)
{
    ...
    services.AddHttpContextIshSingleton<AdminBuilder>();
    ...
}

AnyCSHtmlFile.cshtml

@AdminBuilder.AddStuff()
@AdminBuilder.EnableStuff()
@AdminBuilder.DoStuff()
// It'll then populate the AdminBuilder instance, which needs to be a unique instance for each visit.

Layout.cshtml

这里，我将根据呈现页面时添加的内容，从.cshtml部分文件的底部呈现AdminBuilder。
