1安装包
第一个是基础的配置，第二个包是集成Serilog日志记录器的扩展包，简化在.NET应用程序中集成和配置Serilog的过程。第三个是保存在文档中
2 配置文件
public static void AddSerilog(this WebApplicationBuilder builder)
{
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Override("Microsoft", LogEventLevel.Warning) // 排除Microsoft的日志
.Enrich.FromLogContext() // 注册日志上下文
.WriteTo.Logger(configure => configure // 输出到文件
.MinimumLevel.Debug()
.WriteTo.File(
$"logs\\log.txt", // 单个日志文件，总日志，所有日志存到这里面
rollingInterval: RollingInterval.Day,
outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss} [{Level:u20}] {Message:lj}{NewLine}"
)
)
.CreateLogger();
builder.Host.UseSerilog();
}
Program：
//全局异常计入日志
seriloh存入数据库并到txt文档分表，并显示
1. 配置文档，注入，用哪个装那个
