C# 二进制字符串互转

1.字符转二进制

        public static string ChineseToBinary(string s)
        {
            byte[] data = Encoding.Unicode.GetBytes(s);
            StringBuilder result = new StringBuilder(data.Length * 8);
            foreach (byte b in data)
            {
                result.Append(Convert.ToString(b, 2).PadLeft(8, '0'));
            }
            return result.ToString();
        }

2.二进制转字符

        public static string BinaryToChinese(string input)
        {
            StringBuilder sb = new StringBuilder();
            int numOfBytes = input.Length / 8;
            byte[] bytes = new byte[numOfBytes];
            for (int i = 0; i < numOfBytes; ++i)
            {
                bytes[i] = Convert.ToByte(input.Substring(8 * i, 8), 2);
            }
            return System.Text.Encoding.Unicode.GetString(bytes);
        }
