I have a unicode text with some unicode characters say,"Hello, world! this paragraph has some unicode characters."
I want to convert this paragraph to binary string i.e in binary digits with datatype string. and after converting, I also want to convert that binary string back to unicode string.
If you're simply looking for a way to decode and encode a string into byte[] and not actual binary then i would use System.Text
The actual example from msdn:
string unicodeString = "This string contains the unicode character Pi (\u03a0)";
// Create two different encodings.
Encoding ascii = Encoding.ASCII;
Encoding unicode = Encoding.Unicode;
// Convert the string into a byte array.
byte[] unicodeBytes = unicode.GetBytes(unicodeString);
// Perform the conversion from one encoding to the other.
byte[] asciiBytes = Encoding.Convert(unicode, ascii, unicodeBytes);
// Convert the new byte[] into a char[] and then into a string.
char[] asciiChars = new char[ascii.GetCharCount(asciiBytes, 0, asciiBytes.Length)];
ascii.GetChars(asciiBytes, 0, asciiBytes.Length, asciiChars, 0);
string asciiString = new string(asciiChars);
// Display the strings created before and after the conversion.
Console.WriteLine("Original string: {0}", unicodeString);
Console.WriteLine("Ascii converted string: {0}", asciiString);
Don't forget
using System;
using System.Text;
Since there are several encodings for the Unicode character set, you have to pick: UTF-8, UTF-16, UTF-32, etc. Say you picked UTF-8. You have to use the same encoding going both ways.
To convert to a binary string:
String.Join(
String.Empty, // running them all together makes it tricky.
Encoding.UTF8
.GetBytes("Hello, world! this paragraph has some unicode characters.")
.Select(byt => Convert.ToString(byt, 2).PadLeft(8, '0'))) // must ensure 8 digits.
And back again:
Encoding.UTF8.GetString(
Regex.Split(
"010010000110010101101100011011000110111100101100001000000111011101101111011100100110110001100100001000010010000001110100011010000110100101110011001000000111000001100001011100100110000101100111011100100110000101110000011010000010000001101000011000010111001100100000011100110110111101101101011001010010000001110101011011100110100101100011011011110110010001100101001000000110001101101000011000010111001001100001011000110111010001100101011100100111001100101110"
,"(.{8})") // this is the consequence of running them all together.
.Where(binary => !String.IsNullOrEmpty(binary)) // keeps the matches; drops empty parts
.Select(binary => Convert.ToByte(binary, 2))
.ToArray())
