使用MixedRealityToolkit Unity在自定义消息中发送字节数组

hololens swig network-programming unity3d c#

我正在为全息透镜开发一个共享应用程序,并尝试使用 Custom Messages.cs 包含在 MixedRealityToolkit-Unity .

byte double , float int , long , short 和 Xstring NetworkConnection.[Write/Read]() 重载函数,但我无法获取 NetworkMessage.ReadArray()

我在网络上成功地发送了许多其他自定义消息,因此我知道网络连接不应该成为问题。

正在编写消息

public void SendByteArray(byte[] array)
{
    // If connected to session, broadcast command
    if (serverConnection != null && serverConnection.IsConnected())
    {
        // Create an outgoing network message to contain all the info we want to send
        NetworkOutMessage msg = CreateMessage((byte)TestMessageID.SendArray);

        // Append Command
        msg.WriteArray(array, Convert.ToUInt32(array.Length));

        // Send the message as a broadcast, which will cause the server to forward it to all other users in the session.
        serverConnection.Broadcast(
        msg,
        MessagePriority.Immediate,
        MessageReliability.UnreliableSequenced,
        MessageChannel.Avatar);
    }
}

private byte[] OnArrayReceived(NetworkInMessage msg)
{
    msg.ReadInt64(); // need to read UserID first, but isn't used for this function
    return msg.ReadArray();
}

根据签名,它看起来像是一个复制得不好的、重命名过的书写函数,但我不知道如何修改它。

public virtual void ReadArray(byte[] data, uint arrayLength) {
    global::System.Runtime.InteropServices.GCHandle pinHandle_data = global::System.Runtime.InteropServices.GCHandle.Alloc(data, global::System.Runtime.InteropServices.GCHandleType.Pinned); try {
    {
      SharingClientPINVOKE.NetworkInMessage_ReadArray(swigCPtr, (global::System.IntPtr)pinHandle_data.AddrOfPinnedObject(), arrayLength);
    }
    } finally { pinHandle_data.Free(); }
}

以下是 NetworkInMessage_ReadArray()

但随之而来的是这个警告。

        const uint BUFFER_SIZE = 1024;
        private byte[] OnArrayReceived(NetworkInMessage msg)
        {
            msg.ReadInt64(); // need to read UserID first, but isn't used for this function
            // method 1
            byte[] data = new byte[BUFFER_SIZE];
            ReadArray(ref data, BUFFER_SIZE);
            return data;

            //method 2
            IntPtr dataptr = Marshal.AllocHGlobal(BUFFER_SIZE);
            ReadArray2(dataptr, BUFFER_SIZE);

            byte[] data2 = new byte[BUFFER_SIZE];
            Marshal.Copy(dataptr, data2, 0, BUFFER_SIZE);
            Marshal.FreeHGlobal(dataptr);
            return data2;
        }

        public void ReadArray(ref byte[] data, uint length)
        {
        }
        public void ReadArray2(IntPtr data, uint length)
        {
        }
