c# - 如何使用 DI usinq autofac .net 框架注册 ILogger(Microsoft.Extensions.Logging)

Question

我在 .net 框架项目中使用来自 Microsoft.Extensions.Logging 的 ILogger。
现在我想在容器中注册 ILogger 但我不能。所有答案都是关于 .net core 的。
我试试

var builder = new ContainerBuilder();

builder.RegisterApiControllers(Assembly.GetExecutingAssembly());

//first try
builder.RegisterGeneric(typeof(Logger<>)).As(typeof(ILogger<>));
IServiceCollection services = new ServiceCollection();

//second try
services.AddSingleton(typeof(ILogger<>), typeof(Logger<>));
IContainer container = builder.Build();

httpConfig.DependencyResolver = new AutofacWebApiDependencyResolver(container);

我的类(class)也是

public class TestController : ApiController
{
    private readonly ILogger<TestController > _logger;
    private readonly IService _service;

    public TestController (IService service, ILogger<TestController > logger)
        {
            _service = service;
            _logger = logger;
        }
}

di 是正确的，因为其他服务已正确注入(inject)。
当我在构造函数中包含记录器时，我收到消息
尝试创建类型为“TestController”的 Controller 时发生错误。确保 Controller 具有无参数的公共(public)构造函数。

由于尝试与这些扩展集成，请考虑填充预期的服务集合并在注册完所有内容后填充构建器，

来自文档的示例

var builder = new ContainerBuilder();

builder.RegisterApiControllers(Assembly.GetExecutingAssembly());

IServiceCollection services = new ServiceCollection();

// The Microsoft.Extensions.Logging package provides this one-liner
// to add logging services.
services.AddLogging();

// Once you've registered everything in the ServiceCollection, call
// Populate to bring those registrations into Autofac. This is
// just like a foreach over the list of things in the collection
// to add them to Autofac.
builder.Populate(services);

IContainer container = builder.Build();

httpConfig.DependencyResolver = new AutofacWebApiDependencyResolver(container);
