有没有办法通过配置文件配置Serilog子记录器？

Question

目前我有用代码编写的所有配置。我使用子记录器进行筛选并更改记录的存储。有没有办法从配置文件中做到这一点。因为我想为解决方案中的每个上下文都有单独的配置文件。

Answer 1

如果子记录器的数量是固定在编译的时候，你可以使用配置前缀来做到这一点：

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(); 

有在Serilog.Settings.AppSettings不支持，但在理论上没有什么预防如果某人能够实施它，它会被添加。

试试这个

Startup.cs/Global.asax.cs中

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() 

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"/>
