來(lái)信大神，幫忙幫下面的JAVA代碼轉(zhuǎn)成c#代碼 ? private static final String HEX_CHARS = "0123456789abcdef"; public static String toHexString(byte[] b) { StringBuffer sb = new StringBuffer(); for (int i = 0; i < b.length; i++) { sb.append(HexUtil.HEX_CHARS.charAt(b[i] >>> 4 & 0x0F)); sb.append(HexUtil.HEX_CHARS.charAt(b[i] & 0x0F)); } return sb.toString(); }
