C# Serilog是否在写入文件之前压缩日志消息？

using System;
using System.IO;
using System.IO.Compression;
using Serilog;

class Program
{
    static void Main()
    {
        // 配置Serilog日志记录器
        Log.Logger = new LoggerConfiguration()
            .WriteTo.File("log.txt")
            .CreateLogger();

        try
        {
            // 压缩日志消息并写入文件
            Log.Information("This is a log message");

            using (var fileStream = File.OpenRead("log.txt"))
            using (var compressedStream = File.Create("compressed-log.gz"))
            using (var gzipStream = new GZipStream(compressedStream, CompressionMode.Compress))
            {
                fileStream.CopyTo(gzipStream);
            }

            // 清除原始日志文件
            File.Delete("log.txt");
        }
        catch (Exception ex)
        {
            Log.Error(ex, "An error occurred");
        }
        finally
        {
            // 关闭日志记录器
            Log.CloseAndFlush();
        }
    }
}
