Board index » Visual Studio » Reliable conversion from byte() to string WITHOUT use of System.Text.Encoding

Visual Studio379
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'

Please respond to the newsgroup,

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

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.
