您绝对可以做到这一点.

You can definitely do that.

1. 您需要导入软件包 Serilog.Sinks.File

然后，您必须配置Serilog.

Then you have to configure Serilog.

在program.cs中执行以下操作.

In program.cs do following thing.

Log.Logger = new LoggerConfiguration()
        .MinimumLevel.Debug()
        .MinimumLevel.Override("Microsoft", LogEventLevel.Information)
        .Enrich.FromLogContext()
    .WriteTo.File(
        @"<<your log file path>>",
    fileSizeLimitBytes: 10000000,
    rollOnFileSizeLimit: true,
    shared: true,
    flushToDiskInterval: TimeSpan.FromSeconds(1))
        .CreateLogger();

在buildWebHost函数中添加UseSerilog().

In buildWebHost function add UseSerilog().

public static IWebHost BuildWebHost(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
    .UseStartup<Startup>()
        .UseSerilog() // <-- Add this line
        .Build();

更新1

我已经使用了EventId属性.这只是一个演示，演示了如何基于eventId使用不同的文件，但根据您的要求，您必须自己实现其他功能.

I have used EventId property. This is just demo that how you can use different file based on eventId but for your requirement you have to implement additional thing your own.

Program.cs

Program.cs

public class Program
    {
        public static void Main(string[] args)
        {
            Log.Logger = new LoggerConfiguration()
                .WriteTo.Logger(cc => cc.Filter.ByIncludingOnly(WithProperty("EventId",1001)).WriteTo.File("Test1001.txt",flushToDiskInterval: TimeSpan.FromSeconds(1)))
                .WriteTo.Logger(cc => cc.Filter.ByIncludingOnly(WithProperty("EventId", 2001)).WriteTo.File("Test2001.txt", flushToDiskInterval: TimeSpan.FromSeconds(1)))
                .CreateLogger();

            CreateWebHostBuilder(args).Build().Run();
        }

        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args).UseSerilog()
                .UseStartup<Startup>();

        public static Func<LogEvent, bool> WithProperty(string propertyName, object scalarValue)
        {
            if (propertyName == null) throw new ArgumentNullException("propertyName");           
            ScalarValue scalar = new ScalarValue(scalarValue);
            return e=>
            {
                LogEventPropertyValue propertyValue;
                if (e.Properties.TryGetValue(propertyName, out propertyValue))
                {
                    var stValue = propertyValue as StructureValue;
                    if (stValue != null)
                    {
                        var value = stValue.Properties.Where(cc => cc.Name == "Id").FirstOrDefault();
                        bool result = scalar.Equals(value.Value);
                        return result;
                    }
                }
                return false;
            };
        }
    }

我的HomeController.cs

My HomeController.cs

  public class HomeController : Controller
    {
        ILogger<HomeController> logger;
        public HomeController(ILogger<HomeController> logger)
        {
            this.logger = logger;
        }
        public IActionResult Index()
        {
            logger.Log(LogLevel.Information,new EventId(1001), "This is test 1");
            logger.Log(LogLevel.Information, new EventId(2001), "This is test 2");
            return View();
        } 
    }

注意:主要是您必须使用某种类型的过滤器.
