指定された ILogger に出力を委譲するだけの不毛な ILogger<TCategoryName> 実装

DelegateLogger.cs

using Microsoft.Extensions.Logging;
using System;

namespace Stupid
{
    public class DelegateLogger<TCategoryName> : ILogger<TCategoryName>
    {
        private readonly ILogger _logger;

        public DelegateLogger(ILogger logger) { _logger = logger; }

        public IDisposable BeginScope<TState>(TState state) => _logger.BeginScope(state);

        public bool IsEnabled(LogLevel logLevel) => _logger.IsEnabled(logLevel);

        public void Log<TState>(LogLevel logLevel, EventId eventId, TState state,
            Exception exception, Func<TState, Exception, string> formatter) =>
            _logger.Log(logLevel, eventId, state, exception, formatter);
    }
}
