重点内容：
1 <targets>
2 <target xsi:type="File" name="LogFile" fileName="${basedir}/logs/${shortdate}-${level}.txt"
3 layout="${longdate}|${uppercase:${level}}|${message} ${exception}" />
4 </targets>
5
6 <rules>
7 <logger name="*" minlevel="Debug" writeTo="LogFile" />
8 </rules>
3.3修改StartUp.cs文件
1 public void Configure(IApplicationBuilder app, IHostingEnvironment env,ILoggerFactory loggerFactory)
2 {
3 /*使用NLog*/
4 loggerFactory.AddNLog();
5 env.ConfigureNLog("NLog.config");
6
7 app.UseStaticFiles();
8
9 app.UseMvc(routes =>
10 {
11 routes.MapRoute(
12 name: "default",
13 template: "{controller=Home}/{action=Index}/{id?}");
