Question

目前我所有的配置都是用代码编写的。我使用子记录器来过滤和更改日志记录的存储。有没有办法从配置文件中执行此操作。因为我想为解决方案中的每个上下文分别配置一个配置文件。

Answer 1

如果在构建时修复了子记录器的数量，您可以使用配置前缀来执行此操作：

Log.Logger = new LoggerConfiguration()
    .ReadFrom.AppSettings() // default file
    .WriteTo.Logger(lc => lc
        .ReadFrom.AppSettings(filePath: "other1.config"))             
    .WriteTo.Logger(lc => lc
        .ReadFrom.AppSettings(filePath: "other2.config"))
    .CreateLogger();

Serilog.Settings.AppSettings还没有支持，但理论上如果有人能够实现它，就没有什么能阻止它被添加。

试试这个

Startup.cs / Global.asax.cs

Log.Logger = new LoggerConfiguration()
           .WriteTo
           .Logger(x => x.Filter
           .ByIncludingOnly(logEvent => logEvent.Level == Serilog.Events.LogEventLevel.Error)
           .ReadFrom
           .AppSettings("error"))

           .WriteTo
           .Logger(x => x.Filter
           .ByIncludingOnly(logEvent => logEvent.Level == Serilog.Events.LogEventLevel.Information)
           .ReadFrom
           .AppSettings("info")).CreateLogger()

<强>的Web.Config

<add key ="error:serilog:using:RollingFile" value="Serilog.Sinks.RollingFile"/>
<add key ="error:serilog:write-to:RollingFile.pathFormat" value="C:\log\error {Date}.txt"/>
<add key ="error:serilog:write-to:RollingFile.formatter" value="Serilog.Formatting.Json.JsonFormatter"/>

<add key ="info:serilog:using:RollingFile" value="Serilog.Sinks.RollingFile"/>
<add key ="info:serilog:write-to:RollingFile.pathFormat" value="C:\log\info {Date}.txt"/>
<add key ="info:serilog:write-to:RollingFile.formatter" value="Serilog.Formatting.Json.JsonFormatter"/>

有没有办法通过配置文件配置Serilog子记录器？
