拆分包并获取图像字节 [英] split packet and get image bytes

问题描述

你好，如果我发送带图像字节的数据包到服务器我需要获得唯一的图像字节转换回图像...



客户端：

hello guys if i send packet with image bytes to server i need to get the only image bytes to convert back to image ...

Client side :

public class Image : Writer, Interfaces.IPacket
{
public byte[] Buffer;
public byte[] ImageBytes;

public Image()
{
}

public void Deserialize(byte[] buffer)
{
Buffer = buffer;
}

public byte[] ToArray()
{
Buffer = new byte[(ImageBytes) + 6];
Writer.WriteUInt16(1003, 0 Buffer);
Writer.WriteUint16((ushort)(Buffer.Length), 2, Buffer);
Writer.WriteBytes(ImageBytes, 4, Buffer);
return Buffer;
}
}

和writeBytes：

and writeBytes :

public static void WriteBytes(byte[] arg, int offset, byte[] buffer)
    {
        foreach (byte arg2 in arg)
        {
            if (buffer == null)
                return;
            if (offset > buffer.Length - 1)
                return;
            buffer[offset++] = arg2;
        }
    } 

服务器端：

Server Side :

ushort PacketID = BitConverter.UInt16(packet, 0);
ushort Length = BitConverter.UInt16(packet, 2);

所以我可以从数据包中获取数据包ID和长度...但是如何获取图像字节？

so i can get packet id and length from packet ... but how to get image bytes ?
