如何从.net框架中初始化.NET核心ILogger或ILoggerFactory并注入到.Net核心构建的类库中的构造函数

public class MyLibraryClass
{
    private readonly ILogger<MyLibraryClass> _logger;

    public MyLibraryClass(ILogger<MyLibraryClass> logger)
    {
        _logger = logger;
    }

    // ...
}

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        // ...

        services.AddSingleton<ILoggerFactory, LoggerFactory>();
        services.AddLogging();

        // ...
    }
}

public class Startup
{
    private readonly ILoggerFactory _loggerFactory;

    public Startup(ILoggerFactory loggerFactory)
    {
        _loggerFactory = loggerFactory;
    }

    public void ConfigureServices(IServiceCollection services)
    {
        // ...

        services.AddSingleton<MyLibraryClass>(provider =>
        {
            var logger = _loggerFactory.CreateLogger<MyLibraryClass>();
            return new MyLibraryClass(logger);
        });

        // ...
    }
}

_logger.LogInformation("This is an information message.");
_logger.LogError("An error occurred: {errorMessage}", ex.Message);
