[Terry Olsen]

Looking for info on how to convert a byte array to a string, and string to
byte array. Thanks.

Hi,

Dim strA As String = "A"

Dim arByte() As Byte = System.Text.Encoding.Default.GetBytes(strA)

Dim strByte As String = System.Text.Encoding.Default.GetString(arByte)

Imports System
Imports System.Text

Public Function BytesToString( ByVal buf( ) As Byte) As String
Return Encoding.Unicode.GetString( buf, 0, buf.Length)
End Function

Public Function StringToBytes( ByVal str As String) As Byte( )
Dim byteCount As Integer = Encoding.Unicode.GetByteCount( str, 0, str.Length)
Dim bytes( ) As Byte = New Byte( byteCount) { }
Encoding.Unicode.GetBytes( str, 0, str.Length, bytes, 0)
Return bytes
End Function

Byte array -> string:

'System.Text.Encoding.<encoding>.GetString'

String -> byte array:

'System.Text.Encoding.<encoding>.GetBytes'

Terry,
As the other suggested you need to use a System.Text.Encoding object.

Which Encoding object tends to be the question.

If you have a specific encoding, The System.Text.Encoding class has shared
properties for common encodings. Encoding.Default represents the ANSI
encoding used by Windows as set by Windows Control Panel, most of the time
it is the one you want to use. Encoding.ASCII represents the ASCII encoding.
Remember that ASCII is defined to be 7 bit characters (code points 0 to
127), while ANSI is 8 bit characters based on a specific code page (code
points 0 to 255).

For information on Encodings, Unicode & such see:

Hope this helps
Jay

Everybody is right.
But I use a lot of
Convert.FromBase64String Method
Convert.ToBase64String Method
