创建一个.Net 6 Demo项目

引入NLog包

添加项目配置文件nlog.config

<?xml version="1.0" encoding="utf-8"?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xsi:schemaLocation="NLog NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      autoReload="true" >
    <!-- the targets to write to -->
    <targets>
        <!--单个文件过大会导致写入效率下降,可配置单个文件的最大容量-->
        <target name="File" xsi:type="AsyncWrapper" queueLimit="5000" overflowAction="Discard">
            <target xsi:type="File"
                    fileName="${basedir}/logs/${shortdate}.log"
                    layout="${date:yyyy-MM-dd HH\:mm\:ss} ${level:uppercase=true} ${event-context:item=Action} ${message} ${event-context:item=Amount} ${stacktrace}"
                    archiveAboveSize="10240"
                    archiveEvery="Day"
                    />
        </target>
        <!-- write logs to file -->
        <!--<target xsi:type="File" name="logfile" fileName="c:\temp\console-example.log"
                layout="${longdate}|${level}|${message} |${all-event-properties} ${exception:format=tostring}" />-->
        <!--<target xsi:type="Console" name="logconsole"
                layout="${longdate}|${level}|${message} |${all-event-properties} ${exception:format=tostring}" />-->
    </targets>
    <!-- rules to map from logger name to target -->
    <rules>
        <!--<logger name="*" levels="Debug,Info,Warn,Error" writeTo="File" />-->
        <logger name="*" minlevel="Debug" maxlevel="Error" writeTo="File" />
    </rules>
</nlog>

layout布局:

${longdate} 格式:2022-01-21 17:00:28.4860

后面的毫秒不是我想要的,可以自定义:date:yyyy-MM-dd HH\:mm\:ss

NLog等级

Trace:最常见的记录信息,一般是普通输出

Debug:同样是记录信息,出现的频率比Trace少,一般是调试程序

Info:信息类型的消息

Warn:警告消息

Error:错误消息

自上而下,等级递增

指定特定等级:level="Warn"

指定多个等级:levels="Debug,Info" 以逗号分隔

指定等级范围:minlevel="Info" maxlevel="Error"

<rules>
    <!--<logger name="*" levels="Debug,Info,Warn,Error" writeTo="File" />-->
    <logger name="*" minlevel="Debug" maxlevel="Error" writeTo="File" />
</rules> 

添加工具类 Logger

using NLog;

namespace TestNet6.Utilities
{
    public class Logger
    {
        NLog.Logger _logger { get; set; }
        private Logger(NLog.Logger logger)
        {
            _logger = logger;
        }
        public Logger(string name) : this(LogManager.GetLogger(name))
        public static Logger Default { get; private set; }
        static Logger()
            Default = new Logger(LogManager.GetCurrentClassLogger());
        #region Dedub
        public void Debug(string msg, params object[] args)
            _logger.Debug(msg, args);
        public void Debug(string msg, Exception e)
            _logger.Debug(e, msg);
        #endregion
        #region Info
        public void Info(string msg, params object[] args)
            _logger.Info(msg, args);
        public void Info(string msg, Exception e)
            _logger.Info(e, msg);
        #region Trace
        public void Trace(string msg, params object[] args)
            _logger.Trace(msg, args);
        public void Trace(string msg, Exception e)
            _logger.Trace(e, msg);
        #region Warn
        public void Warn(string msg, params object[] args)
            _logger.Warn(msg, args);
        public void Warn(string msg, Exception e)
            _logger.Warn(e, msg);
        #region Error
        public void Error(string msg, params object[] args)
            _logger.Error(msg, args);
        public void Error(string msg, Exception e)
            _logger.Error(e, msg);
    }
}

添加测试Controller

using Microsoft.AspNetCore.Mvc;
using TestNet6.Utilities;
namespace TestNet6.Controllers
{
    public class TestController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }
        public string Test()
        {
            Logger.Default.Info("", Request);
            return "Test String";
        }
    }
}

最后为了路由有效,还需要添加路由映射

var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
builder.Services.AddRazorPages();
var app = builder.Build();
// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthorization();
app.MapRazorPages();
//添加路由映射
app.MapControllerRoute(name: "default", pattern: "{controller=Home}/{action=Index}/{id?}");
app.Run();

OK,运行测试
