您好，我对这段代码有些问题：
此：
public void SendRegistrationPacket()
{
Packet p = new Packet(PacketType.Registration, "server");
p.Gdata.Add(id);
clientSocket.Send(p.ToBytes());
}
向此发送p.ToBytes()：
public Packet(byte[] packetbytes)
{
BinaryFormatter bf = new BinaryFormatter();
MemoryStream ms = new MemoryStream(packetbytes);
Packet p = (Packet)bf.Deserialize(ms);
ms.Close();
this.Gdata = p.Gdata;
this.packetInt = p.packetInt;
this.packetBool = p.packetBool;
this.senderID = p.senderID;
this.packetType = p.packetType;
}
我在Packet p = (Packet)bf.Deserialize(ms);发现了以下错误：
未处理的类型＆＃39; System.Runtime.Serialization.SerializationException＆＃39;发生在mscorlib.dll中 附加信息：输入流不是有效的二进制格式。起始内容（以字节为单位）为：35-2D-33-39-61-30-63-65-33-65-37-38-33-65-05-FB-FF ...
我不知道我做错了什么......
有人可以帮助我吗？
非常感谢你的时间！

问题来自
readBytes = clientSocket.Receive(buffer);
if (readBytes > 0)
{
//handle data
Packet packet = new Packet(buffer);
DataManger(packet);
}
来自客户端的一个发送不等于服务器上的一个接收。您需要“Message Frameing”，您的Packet仅包含已发送数据的第一部分。
最简单的解决方案是首先发送字节数组的长度，然后让接收方只接收该长度，然后分配该大小的缓冲区，直到它完全填充缓冲区为止。
以下是接收方的快速示例
private static byte[] ReadFully(Socket clientSocket, int length)
{
int offset = 0;
byte[] buffer = new byte[length];
while(offset < length)
{
int read = clientSocket.Receive(buffer, offset, length - offset, SocketFlags.None);
if(read = 0)
return null; //Socket closed
offset += read;
}
return buffer;
}
//read the length
byte[] lengthBuffer = ReadFully(clientSocket, 4);
if(lengthBuffer == null)
{
//Do something about the closed connection
}
int length = BitConverter.ToInt32(lengthBuffer, 0);
//read the number of bytes specified by the length.
byte[] packetBuffer = ReadFully(clientSocket, length);
if (packetBuffer != null)
{
//handle data
Packet packet = new Packet(packetBuffer);
DataManger(packet);
}
我留给你做派遣方。
答案 1 :(得分：0)
我同意以前的评论者。目前还不清楚你的ToBytes（）方法在做什么。你应该做的是这样的事情：
public void SendRegistrationPacket()
{
Packet p = new Packet(PacketType.Registration, "server");
p.Gdata.Add(id);
BinaryFormatter bf = new BinaryFormatter();
MemoryStream ms = new MemoryStream();
bf.Serialize(ms, p);
clientSocket.Send(ms.ToArray());
}
