This is a repo that has a simple yet versatile packets (or messages) framework. This makes it easy to send and receive TCP, UDP, possibly Bluetooth or even serial messages.
This repo also includes a TCP server and client with example console applications.
It's quite easy to create your own packets. A good practice is to create a custom header thats unique for each packet type. This makes it easy to distinguish between different types of packets.
The following is an example of a very basic packet.
using Packets;
public struct EmptyPacket : IPacket
{
private static readonly byte[] Header =
{
(byte) '1',
(byte) '2',
(byte) '3',
(byte) '4',
(byte) '5',
(byte) '6',
(byte) '7',
(byte) '8',
};
public byte[] Serialize()
{
var bytes = new byte[Header.Length];
PacketUtils.WriteHeader(bytes, 0, Header);
return bytes;
}
public bool IsMatch(byte[] bytes, int start, int count)
{
return PacketUtils.MatchesHeader(bytes, start, count, Header);
}
public void Deserialize(byte[] bytes, int start, int count, out int used)
{
used = Header.Length;
}
public IPacket Clone()
{
return this;
}
}For a more complete example that also sends some data back and forth, check out the PingPacket.
