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 * );
             foreach (byte b in data)
             {
                 result.Append(Convert.ToString(b, ).PadLeft(, ''));
             }
             return result.ToString();
         }

2.二进制转字符

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