how to Encoding.ASCII.GetBytes(str)
to Get "0x0d”? 如何
Encoding.ASCII.GetBytes(str)
获取“ 0x0d”?

Encoding.ASCII.GetBytes(hl7).CopyTo(msg, 1);
new byte[] { 0x1c, 0x0d }.CopyTo(msg, len - 2);

I send DSR^Q03 Message to Chemical analyser, Here is the message I sent. 我向化学分析仪发送了DSR ^ Q03消息,这是我发送的消息。 The problem is solved, but I want to get a better solution.
问题已解决,但我想获得更好的解决方案。
As far as I can see you want to encode the given command 据我所知,您想对给定的命令进行编码
string hl7 = @"MSH|^~\&|||...|@DSC||@";
into a format 转换成格式
header = [0x0b]
body = Encoding.ASCII.GetBytes(hl7); each 64 shall be changed into 0x0d
tail = [0x1c, 0x0d]
while changing each 64
into 0x0d
within the body. 同时在体内将每个
64
更改为0x0d
。 You can try using Linq 您可以尝试使用Linq
using System.Linq;
...
string hl7 = @"MSH|^~\&|||...|@DSC||@";
byte[] msg = (new byte[] { 0x0b })
.Concat(Encoding.ASCII.GetBytes(hl7).Select(b => b != 64 ? b : (byte)0x0d))
.Concat(new byte[] { 0x1c, 0x0d })
.ToArray();
tcpServer.Send(client, msg);
