vb.net - 使用带有 MLLP 的 VB.NET 发送 HL7

Question

我正在尝试使用带有 mllp 的 vb.net 发送 hl7，谁能告诉我这是我的代码错误

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

Answer 1

你交换了 endblock 和 returnblock。所以交换它们

Dim EndBlock As String = "0x1c" ' this is end Block <EB>
Dim ReturnBlock As String = "0x0d" ' this is return  <CR>

由于我不熟悉 Visual Basic，我不保证你的 block 的语法定义是正确的，也可以是 &H0D 或类似的。
