Converts a byte array to a string

Array problem

FCL Many methods return values are byte arrays that contain characters instead of returning a string, and such methods are included in the following class:

· System.Net.Sockets.Socket.Receive

· System.Net.Sockets.Socket.ReceiveFrom

· System.Net.Sockets.Socket.BeginReceive

· System.Net.Sockets.Socket.BeginReceiveFrom

· System.Net.Sockets.NetworkStream.Read

· System.Net.Sockets.NetworkStream.BeginRead

· System.IO.BinaryReader.Read

· System.IO.BinaryReader.ReadBytes

· System.IO.FileStream.Read

· System.IO.FileStream.BeginRead

· System.IO.MemoryStream//constructor

· System.IO.MemoryStream.Read

· System.IO.MemoryStream.BeginRead

· System.Security.Cryptography.CryptoStream.Read

· System.Security.Cryptography.CryptoStream.BeginRead

· System.Diagnostics.EventLogEntry.Data

The byte array returned by these methods contains usually ASCII-encoded or Unicode-encoded characters, and many times we may need to convert such a byte array to a string.

Solution

Converts a byte array that contains ASCII-encoded characters into a complete string, using the following methods:

Using System;
Using System.Text;

public static string Fromasciibytearray (byte[] characters)
{
ASCIIEncoding encoding = new ASCIIEncoding ();
String constructedstring = Encoding. GetString (characters);
return (constructedstring);
}


Converts a byte array that contains Unicode encoded characters to a complete string, using the following methods:

public static string Fromunicodebytearray (byte[] characters)
{
UnicodeEncoding encoding = new UnicodeEncoding ();
String constructedstring = Encoding. GetString (characters);
return (constructedstring);
}

The GetString method of the ASCIIEncoding class converts the 7-bitsascii character in a byte array to a string; Any value greater than 127 will be converted to two characters. In the System.Text namespace you can find the ASCIIEncoding class and find the GetString function of the class you can also find that the function has several overloads to support some additional parameters. An overloaded version of this method can also convert a subset of characters from a byte array to string.

The GetString method of converting a byte array to string can be found in the UnicodeEncoding class in the System.Text namespace, which converts a byte array containing 16-bitsunicode characters to a string. Like the GetString method of the ASCIIEncoding class, this method also contains an overloaded version that converts a particular part of a byte array to string.
