有没有一种优化和有效的方法来做到这一点？

Question

我想知道如何优化这种方法。是否可以在列表中添加字节而不覆盖它？

    public void Flush(NetworkStream netStream)
    {
        MinecraftPacketWriter writer = new MinecraftPacketWriter();
        writer.WriteVarInt(buffer.Count);
        byte[] lengthbytes = writer.Buffer.ToArray();
        byte[] bufferbytes = buffer.ToArray();

        byte[] doublebuffer = lengthbytes.Concat(bufferbytes).ToArray();
        writer.Reset();

        buffer = doublebuffer.ToList<byte>();

        RawFlush(netStream);
    }

这是我的全班。

public class MinecraftPacketWriter
{
    private List<byte> buffer = new List<byte>();

    public List<byte> Buffer { get { return buffer; } }

    public void Reset()
    {
        buffer.Clear();
    }
    //.....
    public void Write(byte b)
    {
        buffer.Add(b);
    }

    public void RawFlush(NetworkStream netStream)
    {
        Console.WriteLine("Buffer Bytes Count: {0}", buffer.Count);

        netStream.Write(buffer.ToArray(), 0, buffer.Count);
        Reset();
    }

    public void Flush(NetworkStream netStream)
    {
        MinecraftPacketWriter writer = new MinecraftPacketWriter();
        writer.WriteVarInt(buffer.Count);
        byte[] lengthbytes = writer.Buffer.ToArray();
        byte[] bufferbytes = buffer.ToArray();

        byte[] doublebuffer = lengthbytes.Concat(bufferbytes).ToArray();
        writer.Reset();

        buffer = doublebuffer.ToList<byte>();

        RawFlush(netStream);
    }
}
