static final char[] HEX_CHARS = "0123456789abcdef".toCharArray(); //转换为十六进制 public static String toHexString(byte[] b ) { StringBuilder sb = new StringBuilder(b.length << 2); for (byte x : b) { //byte只有8位 int 则是32位 x& oxff之后会转换为int类型 i

Dictionary 检查后获取值:Dictionary.TryGetValue() KeyValuePair<T, K> 的非泛型形式:DictionaryEntry List 由IList实例获取List实例:List list = new List(ilist) byte string转为byte[]:System.Text.Encoding.UTF8.GetBytes(str) byte[]转为string:System.Text.Encoding.UTF8.GetString(byt
