如何将大文件(12 1GB )分割成多个1 1GB压缩(.gz)的归档文件？C#

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

public class FileSplitter
{
    public static void SplitAndCompressFile(string sourceFilePath, string destinationFolderPath)
    {
        const int chunkSize = 1024 * 1024 * 1024; // 1GB

        using (FileStream sourceFile = File.OpenRead(sourceFilePath))
        {
            byte[] buffer = new byte[chunkSize];
            int bytesRead;

            int fileIndex = 1;
            while ((bytesRead = sourceFile.Read(buffer, 0, buffer.Length)) > 0)
            {
                string destinationFilePath = Path.Combine(destinationFolderPath, $"archive{fileIndex}.gz");

                using (FileStream destinationFile = File.Create(destinationFilePath))
                {
                    using (GZipStream compressionStream = new GZipStream(destinationFile, CompressionMode.Compress))
                    {
                        compressionStream.Write(buffer, 0, bytesRead);
                    }
                }

                fileIndex++;
            }
        }
    }
}

public class Program
{
    public static void Main()
    {
        string sourceFilePath = "path/to/largefile.txt";
        string destinationFolderPath = "path/to/destination/folder";

        FileSplitter.SplitAndCompressFile(sourceFilePath, destinationFolderPath);
    }
}
