Convert a byte Array to a String
The Array class provides methods for creating, manipulating, searching,
and sorting arrays. The Array class is not part of the System.Collections
namespaces. However, it is still considered a collection because it is based
on the IList interface. An element is a value in an Array. The length of an
Array is the total number of elements it can contain. The Array has a fixed
capacity.
The following .net c# tutorial code demonstrates how we can convert a byte Array to a String. That means we will get a String instance from byte Array elements. In this .net c# example code, we will use the ASCIIEncoding class GetString() method and Encoding class GetString() method.
The Encoding class represents the character encoding. Encoding is the process of transforming a set of Unicode characters into a sequence of bytes and decoding is the process of transforming a sequence of encoded bytes into a set of Unicode characters.
ASCIIEncoding class represents an ASCII character encoding of Unicode characters. ASCIIEncoding GetString() method decodes a range of bytes from a byte Array into a String. This method returns a String containing the results of decoding the specified sequence of bytes.
The Encoding class Default property gets the default encoding for this .NET implementation. Encoding GetString(Byte[]) method overload when overridden in a derived class that decodes all the bytes in the specified byte Array into a String. This method returns a String that contains the results of decoding the specified sequence of bytes.
So finally, using this ASCIIEncoding GetString() method and Encoding GetString(Byte[]) method we can convert a byte Array to a String.
