如何将所有流序列化到一个文件中

using System;
using System.IO;

public class StreamSerializer
{
    public static void SerializeStreamsToFile(Stream[] streams, string filePath)
    {
        using (FileStream fileStream = new FileStream(filePath, FileMode.Create))
        {
            // 写入流的数量
            byte[] streamCountBytes = BitConverter.GetBytes(streams.Length);
            fileStream.Write(streamCountBytes, 0, streamCountBytes.Length);

            foreach (Stream stream in streams)
            {
                // 写入流的元数据
                byte[] streamTypeBytes = BitConverter.GetBytes((int)stream.GetType());
                byte[] streamLengthBytes = BitConverter.GetBytes((int)stream.Length);
                fileStream.Write(streamTypeBytes, 0, streamTypeBytes.Length);
                fileStream.Write(streamLengthBytes, 0, streamLengthBytes.Length);

                // 写入流的数据
                byte[] buffer = new byte[1024];
                int bytesRead;
                while ((bytesRead = stream.Read(buffer, 0, buffer.Length)) > 0)
                {
                    fileStream.Write(buffer, 0, bytesRead);
                }
            }
        }
    }
}
