Nlog
Lio 2021-04-06 日志配置
# Nlog使用
首先，当然是引用nuget程序包(NLog.Web.AspNetCore)，然后需要添加Nlog的配置文件,该文件在项目中CfgFiles文件夹下创建nlog.config，并且设置属性如果较新则复制
其次，在项目Project.cs中添加使用Nlog （.UseNLog()）
public class Program
{
public static void Main(string[] args)
{
CreateHostBuilder(args).Build().Run();
}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
}).UseNLog();
}
