I am trying to replace dryIOC container with autofac container for some reason but I don't know the exact syntax how could I resolve ILogger uisng autofac

Here is how I register ILogger in DryIoc

public void Load(IContainer container)
{
    container.Register<ILoggerFactory, Log4NetLoggerFactory>();
    
    ConfigureLogger(container);
}

[Localizable(false)]
private void ConfigureLogger(IContainer container)
{
    container.Register<ILogger>(
        made: Made.Of(
            r => typeof(ILoggerFactory).GetMethod(nameof(ILoggerFactory.Create), new[] {          typeof(Type) }),
            factoryInfo: ServiceInfo.Of<ILoggerFactory>(),
            parameters: Parameters.Of.Name("type", r => r.Parent?.ImplementationType ?? typeof(Startup))),
        reuse: Reuse.Transient);
}

I have tried something like this, but it does not work with Autofac

container.Register<ILoggerFactory, Log4NetLoggerFactory>();

CodePudding user response：

If you try to resolve an instance of Microsoft.Extensions.Logging.ILogger then you have two options:

Option #1 - Resolve a ILogger<TCategoryName>.

public class Something
{
    private readonly ILogger logger;

    public Something(ILogger<Something> logger)
    {
        this.logger = logger;
    }
}

Option #2 - Resolve an ILogger instead of ILogger<TCategoryName> automatically.

My nuget package does exactly this using Autofac:
EgonsoftHU.Extensions.Logging.Autofac

It contains an Autofac module. Register it then magic will happen.

public class Something
{
    private readonly ILogger logger;

    public Something(ILogger logger)
    {
        this.logger = logger; // It will be an instance of ILogger<Something>.
    }
}
