在配置记录器时，您可以做的是扫描所有脚本类，并为它们设置过滤器。
根据您的评论，我们假设您的类看起来像这样：

public abstract class ScriptBase {
  protected ILogger logger;

  // Enrich the logger with SourceContext, in this case, the class type.
  // Child classes will be enriched with their own class names.
  public ScriptBase() { logger = Log.ForContext(this.GetType()); }
  
  public void Test(string s) {
    logger.Debug($"{s} debug");
    logger.Information($"{s} info");
    logger.Error($"{s} error");
  }
}
public class ScriptOne : ScriptBase { }
public class ScriptTwo : ScriptBase { }

字符串
然后我们可以使用SourceContext来设置Matching.FromSource()过滤器。
这将假设你的脚本类是在启动时加载的，并且你没有在运行时动态加载DLL。

using System;
using System.Linq;
using Serilog;
using Serilog.Events;
using Serilog.Filters;

class Program {
  // Include Context in the template, to make the `Everything` log easier to read.
  const string template = "{Timestamp:HH:mm:ss.fff} [{Level:u3}] {SourceContext}: {Message}{NewLine}{Exception}";
  const RollingInterval interval = RollingInterval.Day;
  const string logDir = "c:/temp/logs"; // or wherever

  static void Main() {
    // We'll build up the Logger Config in a few steps.
    var logConfig = new LoggerConfiguration()
      // Allow Debug and above globally. We can override this per sink later.
      .MinimumLevel.Debug()
      ;

    // Step 1. Find ALL classes inheriting from ScriptBase.
    var scriptTypes = AppDomain.CurrentDomain.GetAssemblies()
      .SelectMany(assembly => assembly.GetTypes())
      .Where(typ => typeof(ScriptBase).IsAssignableFrom(typ))
      ;

    // Step 2. For each of the classes found above, 
    // configure the directory using filters.
    foreach (var type in scriptTypes) {
      logConfig = logConfig
        .WriteTo.Logger(lc => lc
          // Filter by the class name
          .Filter.ByIncludingOnly(Matching.FromSource(type.FullName))
          // And use it as subdirectory
          .WriteTo.File($"{logDir}/{type.Name}/Log-.log",
            rollingInterval: interval, outputTemplate: template
          )
        );
    }

    // Step 3. The rest of the config.
    logConfig = logConfig
      // Global file sink for everything
      .WriteTo.File($"{logDir}/EverythingLog-.log",
        rollingInterval: interval, outputTemplate: template,
        // Let's only log Info for the global file
        restrictedToMinimumLevel: LogEventLevel.Information
      )
      // And maybe restrict the Console sink to Warnings/Errors
      .WriteTo.Console(restrictedToMinimumLevel: LogEventLevel.Warning)
      ;

    // Use the config above to initialise the logger.
    Log.Logger = logConfig.CreateLogger();

    // Now let's test the different scripts.
    new ScriptOne().Test("Hello");
    new ScriptTwo().Test("World");
  }
}
