添加对每个请求唯一的自定义单例

Question

我一直在努力找出 asp net core 附带的依赖模式。这就是我想要实现的目标。

_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

在这里，我将根据呈现页面时添加的内容，从部分 .cshtml 文件呈现底部的 AdminBuilder。

Answer 1

使用services.AddScoped<AdminBuilder>().
