Serilog日志组件
在.NET6 WPF中使用
//需要先引入Serilog、Serilog.Extensions.Hosting包
new HostBuilder()
//.ConfigureServices((context, services) =>{services.AddLogging(loggerbuild => loggerbuild.AddSerilog(dispose: true));}) // 这句
.UseSerilog() // 或者这句都能引入 (需要Serilog.Extensions.Hosting)
//.UseSerilog((hostingContext, services, loggerConfiguration) => loggerConfiguration.ReadFrom.Configuration(hostingContext.Configuration)) //直接内联初始化 就不用在OnStartup()中单独new LoggerConfiguration().CreateLogger()了
.Build();在程序中配置
private async void OnStartup(object sender, StartupEventArgs e)
{
Log.Logger = new LoggerConfiguration()
.Enrich.WithProperty("zidingyi", "1.0.0.0") //增加新的属性，可用于展示到输出模板
.Enrich.WithProperty("Count", 2)
//.Destructure.ByTransforming<HttpRequest>(r => new { RawUrl = r.RawUrl, Method = r.Method }) //格式化http请求输出 未测试
.MinimumLevel.Verbose() //设置日志写入的最低等级，其他方式中自己设置的等级只能高于这个等级，低于就不生效。 Serilog 默认输出等级是info
.MinimumLevel.Override("Microsoft", Serilog.Events.LogEventLevel.Warning) //重写系统日志等级 让其不输出到info
.MinimumLevel.Override("System", Serilog.Events.LogEventLevel.Warning)
//写入文件引入 Serilog.Sinks.File
.WriteTo.File("log-info.log",
rollOnFileSizeLimit:true, //开启根据大小分文件
fileSizeLimitBytes: 1024, //10*1024*1024=10MB 单文件最大体积 达到后生成新的文件
retainedFileCountLimit:60,// 保留文件数量， 默认31，传空一直保留
rollingInterval: RollingInterval.Day,
outputTemplate: "{Timestamp:yy/MM/dd HH:mm:ss.fff} [{Level:w4}] {Message:lj}{NewLine}{Exception}{NewLine}"
/*
* {Level:u3} {Level:w4}:输出日志等级u代表大写 w代表小写 数字代表输出几位 3:inf INF ERR err 4:INFO ERRO
* {Message:lj} ：j:输出内容按照json格式，字符串 还是输出字符串
* {Properties:j} 输出上下文信息
*
*/
)
.WriteTo.File("log-err.log",
rollingInterval: RollingInterval.Day,
restrictedToMinimumLevel: Serilog.Events.LogEventLevel.Error, //单独记录错误等级的日志
outputTemplate: "{zidingyi} {Timestamp:yy/MM/dd HH:mm:ss.fff} [{Level:u3}] {Message:lj}{NewLine}{Exception}{NewLine}")
//写入数据接口引入对应的数据库包 Serilog.Sinks.SQLite
.WriteTo.SQLite(@"Log\log.db", "log")
//.WriteTo.Console(restrictedToMinimumLevel: Serilog.Events.LogEventLevel.Verbose)
.CreateLogger();
await _host.StartAsync();
}在配置文件中使用
private async void OnStartup(object sender, StartupEventArgs e)
{
//使用配置文件 引入Serilog.Settings.Configuration包
var configuration = new ConfigurationBuilder().AddJsonFile("appsettings.json").Build();
Log.Logger = new LoggerConfiguration()
.ReadFrom.Configuration(configuration).CreateLogger();
await _host.StartAsync();

}File Sink本身并不直接支持Filter配置。 Filter是Logger级别的概念，不是Sink级别的：它是Logger pipeline的一部分，而不是单个Sink的特性。 过滤依赖Serilog.Expressions包
主 Sink配置过滤
主Logger只会输出Scan日志，其他日志都被过滤掉了。
