Can not serialize a custom array HELP!

TetraGames

Hello fellows ,
I am trying to serialize a custom array. like this ;

public static readonly byte[] memState = new byte[4 * 2 + 2];
// 1 short - 2 float = 80 bit = 10 byte
private static short SerializeState(StreamBuffer outStream, object customobject)
{
// reference it
State state = (State)customobject;

// serialize array
byte[] projectileArr = Protocol.Serialize(state.projectiles); // This line throwing an error.

int i = memState.Length + projectileArr.Length;

lock (memState)
{
byte[] bytes = new byte[memState.Length + projectileArr.Length]; // a byte array size of state

int index = 0;

Protocol.Serialize(state.sequence, bytes, ref index); // Sequence of packet
Protocol.Serialize(state.position.x, bytes, ref index); // x position
Protocol.Serialize(state.position.y, bytes, ref index); // y position

System.Array.Copy(projectileArr, 0, bytes, index, projectileArr.Length);

index += projectileArr.Length;

outStream.Write(bytes, 0, (10 + state.projectiles.Length * (4 * 2)));
}

int count = 10 + state.projectiles.Length * (4 * 2);

return (short)count;
}

That is the output ; NotSupportedException: cannot serialize array of type ProjectileState

What do you guys think ?

Solved by registering projectileArray class for serialization.
