Encoding.GetString(Byte[]):

Encoding.GetString(Bytes[]) method is use to decode the specified byte of an array to string. This method needs a encoding class to make a encoding object. This encoding object can be a following two classes:

1. UTF-8 encoded---> UTF is Unicode Transformation Format and “8” is used because it takes 8-bit blocks to represent a character.

2. ASCIIEncoding-----> ASCII is American Standard Code for Information Interchange it is used to represent the characters in numeric form. It takes 7-bits to represent an ASCII character.

UTF-8 encoded class is used when we want to make our code secure and allow the error detection because ASCIIEncoding does not allow the error detection.

Syntax:

        public virtual string GetString( byte[] bytes)

It accepts one parameter "bytes" which specifies a array bytes .

It returns a decoded string of specified array bytes.

Exceptions:

This method throws the following exceptions:

1. ArgumentNullException -------------> It occurs if the byte array is null.

2. DecoderFallbackException -------> It occurs if DecoderFallback is set to DecoderExceptionFallback.

To convert byte array to string using this method, see the below code:

We are using an ASCIIEncoding object in this exapmle:

namespace GetStringASCIIEncoding
 {
    class Program
    {
      static void Main(string[] args)
        {
            byte[] arrayBytes = { 102 , 101 , 103 , 98 , 97 };
            string str = System.Text.ASCIIEncoding.ASCII.GetString(arrayBytes );
            Console.WriteLine("String: "+str);
            
         }
     }
 }

Output:

fegba

We are using a UTF-8 encoded object in this exapmle:

namespace GetStringUTF8Encoding
{
   class Program
    {
      static void Main(string[] args)
       {
           byte[] arrayBytes = { 102 , 101 , 103 , 98 , 97 };
           string str1 = System.Text.Encoding.UTF8.GetString(arrayBytes);
           Console.WriteLine("String: "+str);
            
       }
    }
}

Output:

fegba
