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

Rating:

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);
