vb.net - VB.NET と MLLP を使用して HL7 を送信する

Question

mlp で vb.net を使用して hl7 を送信しようとしていますが、私のコードが間違っていると誰か教えてもらえますか?

Dim StartBlock As String = "0x0b"  ' this is start block <SB>
Dim EndBlock As String = " 0x0d" ' this is end Block <EB>
Dim ReturnBlock As String = "0x1c" ' this is return  <CR>
Msg = StartBlock & Msg & EndBlock & ReturnBlock 


Dim networkStream As NetworkStream = tcpClient.GetStream()

If networkStream.CanWrite And networkStream.CanRead Then
    Dim sendBytes As [Byte]() = Encoding.ASCII.GetBytes(Msg) 

    networkStream.Write(sendBytes, 0, sendBytes.Length)
end if
