下面是一个示例代码,演示如何使用上面的工具类将字符串转换为byte数组: publicclassMain{publicstaticvoidmain(String[]args){Stringstr="Hello, world!";byte[]bytes=StringUtils.stringToBytes(str);System.out.println("String: "+str);System.out.print("Byte array: ");for(byteb:bytes){System.out.print(...
System.out.println("length of byte array in UTF-8 : "+ utf8.length); System.out.println("contents of byte array in UTF-8: "+ Arrays.toString(utf8)); 备注 1)这是将String转换为Java中的字节数组的最佳方法。 2)这不会引发java.io.UnsupportedEncodingException异常 3)牢记,StandarhardCasets类...
public static byte[] ConvertStringToBytes(string input) { MemoryStream stream = new MemoryStream(); using (StreamWriter writer = new StreamWriter(stream)) writer.Write(input); writer.Flush(); return stream.ToArray(); } The above snippet uses the Writer class, which is a stream-oriented cl...
