C#串行数据被分割成随机数量，试图在没有运气的情况下找到回车

您好，我制作了一个C#应用程序，用于从我的Arduino读取串行数据，当且仅当我在发送数据时在Arduino上使用Serial.println时，我的应用程序才能通过使用ReadLine（）正确获取所有数据，因为\n\r Arduino附加了printline

但是，如果我只是使用Serial.print从Arduino正常发送数据，而Serial.print没有\n，因此使用ReadExisting（），我无法一次获取所有文本。我获取的文本数量可能是随机的，可能是流的一半，或者只有2个字符，然后是10和6，这是完全随机的。我曾尝试将文本放在字符数组中，并使用Contains或EndsWith、readChar和readByte来查找“null或CR或ETX或EOT”，但运气不佳

请问我能做些什么来检测流的尽头，欢迎任何指导

编辑：：经过一番思考后，我发现即使使用

port.ReadExisting（）

随机分割数据，文本中缺失的部分很快就会出现，远远小于Arduino每次传输之间的间隔（目前为1秒）。因此，如果下一个数据包的时间接近，我将尝试将它们连接在一起

这是我为收到的文本的每个部分制作的一个简单日志，请注意，我现在把它作为csv格式，只是为了测试我的查找功能。它并不总是那种格式
