示例1: AppendPayloadAsHeader
public static ArraySegment<byte> AppendPayloadAsHeader(ArraySegment<byte> buffer, ArraySegment<byte> payload, BufferManager bufferManager)
{
// We will insert at the beginning of the buffer just before the dictionary or any message content
int posToInsert = buffer.Offset;
int frameSize = PayloadMarkLength + PayloadLengthByteCount + payload.Count;
byte[] newBuffer = bufferManager.TakeBuffer(buffer.Count + frameSize + buffer.Offset);
int afterContent = posToInsert + frameSize;
// Insert our custom mark 0xBE
int insertPoint = posToInsert;
newBuffer[insertPoint++] = PayloadMark;
// Insert the length of the payload
byte[] lenInBytes = BitConverter.GetBytes(payload.Count);
newBuffer[insertPoint++] = lenInBytes[0];

// Copy from old to new array
Buffer.BlockCopy(buffer.Array, 0, newBuffer, 0, posToInsert); // Copy until the subheader pointer
Buffer.BlockCopy(buffer.Array, posToInsert, newBuffer, afterContent, buffer.Count - posToInsert + buffer.Offset); // Now copy the rest
