如何在.NET核心中使用appsettings.json而不是nlog.config文件配置NLog？
如何在.NET核心中使用appsettings.json而不是nlog.config文件配置NLog？
提问于 2019-05-22 05:10:36
NLog文档解释了如何使用XML文件为.NET核心应用程序配置nlog.config。但是，我更希望我的应用程序只有一个配置文件-- appsettings.json。对于.NET框架应用程序，可以将NLog配置放在app.config或web.config中。是否可以用同样的方式将NLog配置放入appsettings.json？
例如，如何将此配置示例从NLog documentation for ASP.NET Core 2放入appsettings.json
<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
autoReload="true"
internalLogLevel="Info"
internalLogFile="c:\temp\internal-nlog.txt">
<!-- enable asp.net core layout renderers -->
<extensions>
<add assembly="NLog.Web.AspNetCore"/>
</extensions>
<!-- the targets to write to -->
<targets>
<!-- write logs to file -->
<target xsi:type="File" name="allfile" fileName="c:\temp\nlog-all-${shortdate}.log"
layout="${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${message} ${exception:format=tostring}" />
<!-- another file log, only own logs. Uses some ASP.NET core renderers -->
<target xsi:type="File" name="ownFile-web" fileName="c:\temp\nlog-own-${shortdate}.log"
layout="${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${message} ${exception:format=tostring}|url: ${aspnet-request-url}|action: ${aspnet-mvc-action}" />
</targets>
<!-- rules to map from logger name to target -->
<rules>
<!--All logs, including from Microsoft-->
<logger name="*" minlevel="Trace" writeTo="allfile" />
<!--Skip non-critical Microsoft logs and so log only own logs-->
<logger name="Microsoft.*" maxlevel="Info" final="true" /> <!-- BlackHole without writeTo -->
<logger name="*" minlevel="Trace" writeTo="ownFile-web" />
</rules>

补充罗尔夫·克里斯滕森的回应。
具有数据库目标的appsettings.json。

当你有一个控制台应用程序(我使用的是NET5)时，你可以这样做：
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureServices((hostContext, services) =>
{
...
}).ConfigureLogging((hostContext, logBuilder) =>
{
logBuilder.AddNLog(new NLogLoggingConfiguration(hostContext.Configuration.GetSection("NLog"))).SetMinimumLevel(LogLevel.Trace);
})
.UseConsoleLifetime();页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
