C# 里面的byte[] 是这样的
传输到Android是 List< String > ["161","180","122","120","161","180"]
如何把 这个字符串转换成对等C#里的 byte[]
回复讨论(解决方案)
String[] array = new String[list.size()]; list.toArray(array);
//字符序列转换为16进制字符串
private String bytesToHexString(byte[] src) {
StringBuilder stringBuilder = new StringBuilder("0x");
if (src == null || src.length < = 0) {
return null;
}
char[] buffer = new char[2];
for (int i = 0; i < src.length; i++) {
buffer[0] = Character.forDigit((src[i] > > > 4) & 0x0F, 16);
buffer[1] = Character.forDigit(src[i] & 0x0F, 16);
System.out.println(buffer);
stringBuilder.append(buffer);
}
return stringBuilder.toString();
}
private byte[] hexStringToByteArray(String s) {
int len = s.length();
byte[] data = new byte[len / 2];
for (int i = 0; i < len; i += 2) {
data[i / 2] = (byte) ((Character.digit(s.charAt(i), 16) < < 4) + Character.digit(s.charAt(i + 1), 16));
}
return data;
}
