C＃二進制數據轉換爲字符串

這是交易。我找到了一個源代碼並稍微改了一下，所以我可以從com6上的接收器中檢索數據。我收到的數據是二進制的。我想要的是將它轉換爲一個字符串，所以我可以剪切部分字符串並單獨解碼。我怎樣才能做到這一點？源代碼位於下方。C＃二進制數據轉換爲字符串

我想，如果你使用_SerialPort.ReadLine（），只有給你的字符串。顯示你是否收到數據。我的意思是你收到的二進制格式。 – 2011-06-02 12:44:41

來自端口的數據將始終以二進制（字節）形式存在，因此它取決於如何解釋數據。假設字節是ASCII碼，可以按如下其編碼爲一個字符串：

byte[] binaryData ; // assuming binaryData contains the bytes from the port. 

string ascii = Encoding.ASCII.GetString(binaryData);
