The reason I want to do so, is that I am sending to DOS and I am pretty
certain that it will not work.
Everything I've tried so far hasnt.
In my test environment (Windows to Windows) this works perfectly, but not
when sending to DOS:
Private Function bytearray2string(ByVal input As Byte()) As String
Dim output As String
output = System.Text.Encoding.Default.GetString(input)
Return output
End Function
Private Function string2bytearray(ByVal input As String) As Byte()
Dim output() As Byte
output = System.Text.Encoding.Default.GetBytes(input)
Return output
End Function
I have also tried this, to no avail in Windows:
Private Function bytearray2string2(ByVal input As Byte()) As String
Dim output As String = ""
Dim i As Integer = 0
'Dim vchar As Char
While i < input.Length
output = output & CChar(Chr(input.GetValue(i)))
i = i + 1
End While
Return (output)
End Function
Private Function string2bytearray2(ByVal input As String) As Byte()
Dim output(input.Length - 1) As Byte
Dim i As Integer = 0
For i = 0 To UBound(output)
output(i) = CByte(Asc(input.Chars(i)))
Next
Return (output)
End Function
The desired functions need to use no encoding and be able to work with
simple bytes. The values I'll be receiving wont be higher anyway.
I'd appreciate any feedback whatsoever.

Why not use ASCII encoding, instead of 'Default'

ASCII Encoding uses 7 bits out of the byte, so I'd be losing 1 bit out of
every byte of data that comes in.
I want to use the extended ASCII that uses all 8 bits, for values of 0 to
255.

Maybe codepage 850 is what you're looking for.
System.Text.Encoding.GetEncoding(850)
Use it to convert from/to byte arrays. There are other codepages
See also: http://www.microsoft.com/globaldev/r...ce/cphome.mspx
To find the right encoding, open a DOS window and enter
mode con cp<enter>
Should return the encoding you need (but I'm not sure)

Thanx a lot for the tip. Will try that.
Seems like a reliable way of getting the encoding. Maybe codepage 850 is what you're looking for.
