Nlog相关资料：
https://github.com/NLog/NLog/wiki/Getting-started-with-ASP.NET-Core-2
https://github.com/NLog/NLog.Web/tree/master/examples/ASP.NET%20Core%202/Visual%20Studio%202017/ASP.NET%20Core%202%20-%20VS2017
1 nuget安装NLog.Web.AspNetCore
2 在web应用程序Program.cs中对照修改代码
|
1 2 3 4 5 6 7 8 9 |
public static IWebHostBuilder CreateWebHostBuilder(string[] args) => WebHost.CreateDefaultBuilder(args) .UseStartup<Startup>() .ConfigureLogging(logging => { logging.ClearProviders(); logging.SetMinimumLevel(LogLevel.Trace); }) .UseNLog(); |
3 在相应的控制器中修改
|
1 2 3 4 5 6 7 8 9 10 11 12 |
private readonly ILogger<HomeController> _logger; public HomeController(ILogger<HomeController> logger) { _logger = logger; } public IActionResult Index() { _logger.LogInformation("hello--index"); return View(); } |
4 在web应用程序中添加nlog.config配置文件，并设置为较新则复制或始终复制

Log4Net相关资料：
https://github.com/huorswords/Microsoft.Extensions.Logging.Log4Net.AspNetCore
1 nuget安装Microsoft.Extensions.Logging.Log4Net.AspNetCore
2 修改web应用程序program.cs
|
1 2 3 4 5 6 7 8 9 10 11 |
public static IWebHostBuilder CreateWebHostBuilder(string[] args) => WebHost.CreateDefaultBuilder(args) .UseStartup<Startup>() .ConfigureLogging((hostingContext, logging) => { // The ILoggingBuilder minimum level determines the // the lowest possible level for logging. The log4net // level then sets the level that we actually log at. logging.AddLog4Net(); logging.SetMinimumLevel(LogLevel.Debug); }); |
3 在相应的控制器中修改
|
1 2 3 4 5 6 7 8 9 10 11 12 |
private readonly ILogger<HomeController> _logger; public HomeController(ILogger<HomeController> logger) { _logger = logger; } public IActionResult Index() { _logger.LogInformation("hello--index"); return View(); } |
4 在Web应用程序中添加log4net.config，并设置为较新复制或始终复制
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |

运行程序，会在Web应用程序目录下生成日志文件
