 Program 文件配置

 public static void Main(string[] args)
        {
            NLog.Web.NLogBuilder.ConfigureNLog("nlog.config");
            CreateHostBuilder(args).Build().Run();
        }

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                }).ConfigureLogging(logging =>
                {
                    logging.ClearProviders(); //移除已经注册的其他日志处理程序
                    logging.SetMinimumLevel(Microsoft.Extensions.Logging.LogLevel.Trace);//设置最小的日志级别
                }).UseNLog();

 使用

  public class HomeController : Controller
    {
        private readonly ILogger<HomeController> _logger;

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

        public IActionResult Index()
        {

            _logger.LogError("xxxxxxxxxxxLogError");

            _logger.LogInformation("xxxxxxxxxxxLogInformation");
