Too many bytes received on my server socket

I have a listening socket on my UWP device.

This the code for that:

List<byte> requestInBytes = new List<byte>();

using (IInputStream input = args.Socket.InputStream)
{
    byte[] data = new byte[BufferSize];
    IBuffer buffer = data.AsBuffer();
    uint dataRead = BufferSize;
    while (dataRead == BufferSize)
    {
        await input.ReadAsync(buffer, BufferSize, InputStreamOptions.Partial);
        requestInBytes.AddRange(data);
        dataRead = buffer.Length;
    }
}
var ct = requestInBytes.Count;

The count returned on that is:

630784

On my client Winform desktop I am sending the byte array as follows:

using (TcpClient clientSocket = new TcpClient())
{
    await clientSocket.ConnectAsync(GeneralTags.RASPBERRY_PI_IP_ADDRESS, GeneralTags.RASPBERRY_PI_PORT);
    using (NetworkStream serverStream = clientSocket.GetStream())
    {
        List<byte> requestInBytes = new List<byte>();

        serverStream.Write(byteArray, 0, byteArray.Length);
        serverStream.Flush();
    }
}

The count of what I am sending is:

626840

Why are there more bytes received into my server?

The problem is that you add the entire buffer array data regardless of the actual number of received bytes.

Change the line

requestInBytes.AddRange(data)

to

requestInBytes.AddRange(data.Take(buffer.Length))
