How to use the UTF8Encoding class to encode and decode a text?

The steps to use the UTF8Encoding class to encode and decode a text data are as follows:

1. Implement the following namespace:

    

   using System.Text;

2. Create a UTF8Encoding class object as follows:

   UTF8Encoding utf8 = new UTF8Encoding();

3. Create a string object to store input text as follows:

   String unicodeString =”This unicode string contains two characters with codes outside an 8-bit code range,Pi (u03a0) and Sigma (u03a3)”;

4. Encode the given text in the following manner:

   Byte[] encodedText = utf8.GetBytes(unicodeString);

 

5. Display the encoded text as follows:

   foreach (Byte bt in encodedText)
   Console.Write(“[{0}]“, bt);

6. Decode the encoded text as follows:

   String decodeStr = utf8.GetString(encodedText);

7. Display the decoded text as follows:

   Console.WriteLine(decodedStr);
