Qt Demo,需要将字符串与byte数组互转,参考: https://stackoverflow.com/questions/37802575/qt-c-qstring-to-qbytearray-conversion 代码很简单: 1. 字符串转byte数组 QString str = "ABC"; QByteArray bytes = str.toUtf8(); 2. byte数组转字符串
String class also has a method to convert a subset of the byte array to String. byte[] byteArray1 = { 80, 65, 78, 75, 65, 74 }; String str = new String(byteArray1, 0, 3, StandardCharsets.UTF_8); Above code is perfectly fine and ‘str’ value will be ‘PAN’. That’s a...

First use an encoding to convert the string to an array of bytes. I suggest UTF8 or ASCII. Then use Convert.ToString( n, 2 ) to convert each byte to a string in base 2. (using 1's and 0's.) You can use .PadLeft( 8, '0' ) to ensure that there are leading zeroes and tha...
