核心的包是 Serilog 和 Serilog.AspNetCore
建议安装 Serilog.AspNetCore，几乎包含了Serilog常用的所有包
异步写入 Serilog.Sinks.Async
写入MSSQL Serilog.Sinks.MSSqlServer
Install-Package Serilog.AspNetCore
Install-Package Serilog # winform 安装
Install-Package Serilog.Sinks.Async
Install-Package Serilog.Sinks.MSSqlServer

WriteTo.File详解
path：默认路径是程序的bin目录+path参数，当然也可以写绝对路径，只需要写入参数就可以了
rollingInterval：创建文件的类别，可以是分钟，小时，天，月。 此参数可以让创建的log文件名 + 时间。例如log20191219.log
outputTemplate：日志模板，可以自定义
retainedFileCountLimit：设置日志文件个数最大值，默认31，意思就是只保留最近的31个日志文件,等于null时永远保留文件

在Program.cs程序启动时注入Serilog 加载配置，有两种方法：
1.
using System;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Hosting;
using Serilog;
namespace WebApplication1

public class Program

.MinimumLevel.Debug()
.WriteTo.Console()
.WriteTo.File($"{AppContext.BaseDirectory}00_Logs\\log.log", rollingInterval: RollingInterval.Day)
.CreateLogger();
try
{
Log.Information("Starting up");
CreateHostBuilder(args).Build().Run();
}
catch (Exception ex)
{
Log.Fatal(ex, "Application start-up failed");
}
finally
{
Log.CloseAndFlush();
}
}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
})
.UseSerilog();
}
}
using System;using Microsoft.AspNetCore.Hosting;

}

.ConfigureWebHostDefaults(webBuilder =>
{

webBuilder.UseSerilog((hostingContext, loggerConfiguration) =>
{

.ReadFrom.Configuration(hostingContext.Configuration)
.Enrich.FromLogContext()
.WriteTo.File($"{AppContext.BaseDirectory}00_Logs\\log.log", rollingInterval: RollingInterval.Day)

});
});
