DECODE IN C#

Introduction:

Decoder transforms a series of encoded data into a character set. In this tutorial, we will brief about the decoding in C#.

Inheritance Object                Decoder

Syntax for decode in C#:

The syntax for decoding the encoded bytes in C# is :

public abstract class class_name

Example:

The usage of a decoder to transform two separate byte arrays towards a character array is illustrated in the following example. The arrays are separated by a single byte of the character. This is comparable to the internal reading of a stream that a StreamReader object performs.

using System;

using System.Text;

public class decoder

{

    public static void Main ()

    {

        byte [] bytes_1 = { 0x20, 0x23, 0xe2 };

        byte [] bytes_2 = { 0x98, 0xa3 };

        char [] character = new char [3];

        Decoder dec = Encoding.UTF8.GetDecoder ();

        int charLength = dec.GetChars ( bytes_1, 0, bytes_1.Length, character, 0);

        charLength += dec.GetChars (bytes_2, 0, bytes_2.Length, character, charLength);

        foreach (char c in character)

            Console.Write (" U+{0:X4}  ", (ushort) c);

    }

}

Output:

Explanation:

To retrieve a specific instance belonging to the decoder class implementation, utilize an Encoding implements GetDecoder function. The GetChars method does the decoding; the GetCharCount method calculates several characters that are required to decode a given set of bytes. Both of these techniques have many versions defined in the Decoder class. For accurately decoding byte sequences, that consist of blocks, a Decoder object keeps track of state information between consecutive calls to the GetChars as well as Convert methods.

Additionally, at the conclusion of data blocks, the Decoder saves trailing bytes, which it uses in the subsequent decoding operation. Consequently, because the operations of files as well as the network transmission frequently deal with fragments of data rather than a full data stream, GetDecoder as well as GetEncoder are helpful for these tasks.

Note: The application needs to ensure that the state data is drained by modifying the flush variable to true in the relevant method call after it has finished processing a stream of data. The program must execute Reset to remove the internal state associated with the Decoder object in the event of an exception or when switching streams.

• While implementing the program, your application needs to override every element when it inherits through this class.

Constructors:

Decoder ()                         creates a new Decoder class instance and establishes it.

Properties:

• Fallback: With the current Decoder object, obtains or defines a DecoderFallback object.
• FallbackBuffer: Obtains the object DecoderFallbackBuffer connected to the active Decoder object.

Conclusion:

Decode in C# is used to convert encoded data into the character set.
