How to convert byte() to string, and from string back to byte()

[moondaddy]

I'm writing an app in vb.net 1.1 and need to convert a byte array into a
string, and then from a string back to a byte array.

for example

Private mByte() as New Byte(4){11,22,3 3,44}

Now how do I convert it to:
dim myStr as string = "11,22,33,4 4"

and then back to the byte array?

Thanks.

Moondaddy,

Have a look at the encode functions GetString and GetBytes.

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemtextencodingclassgetstringtopic.asp

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemtextutf8encodingclassgetbytestopic2.asp

I hope this helps,

Cor

Hi

I thin you may need to use the code similar with below.
Private Sub Button3_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button3.Click
Dim mByte() As Byte = New Byte(3) {11, 22, 33, 44}
Dim strs(3) As String
For i As Integer = 0 To 3
strs(i) = mByte(i).ToStri ng()
Next
For Each s As String In strs
Debug.WriteLine (s)
Next
Dim b As Byte = Convert.ToByte( strs(0))
End Sub

If you wants to transfer the data as a string type, I think you may try to
use the Base64encoding.
Dim ss As String = Convert.ToBase6 4String(mByte)
MsgBox(ss)
Dim mb() As Byte = Convert.FromBas e64String(ss)

Re: How to convert byte() to string, and from string back to byte()

moondaddy,
In addition to the other comments:

Does your byte array contain Char codes, such as ASCII, ANSI, or Unicode
characters? In which case you can use System.Text.Enc oding.GetBytes &
Encoding.GetStr ing to convert to & from a string (as Cor & Herfried
suggested).

Of if you simply want a comma delimited list of numbers from the Byte Array
I would create a couple of helper functions (As Peter suggested).

Something like:

Private Shared Function ArrayToString(B yVal bytes() As Byte, Optional
ByVal format As String = Nothing) As String
If bytes.Length = 0 Then Return String.Empty
Dim sb As New System.Text.Str ingBuilder(byte s.Length * 4)
For Each b As Byte In bytes
sb.Append(b.ToS tring(format))
sb.Append(","c)
Next
sb.Length -= 1
Return sb.ToString()
End Function

Private Shared Function StringToArray(B yVal s As String, Optional ByVal
style As System.Globaliz ation.NumberSty les = Nothing) As Byte()
If s.Length = 0 Then Return New Byte() {}
Dim values() As String = s.Split(","c)
Dim bytes(values.Le ngth - 1) As Byte
For index As Integer = 0 To values.Length - 1
bytes(index) = Byte.Parse(valu es(index), style)
Next
Return bytes
End Function

Public Shared Sub Main()

Dim mByte() As Byte = New Byte() {11, 22, 33, 44}
Dim myStr As String

'myStr = ArrayToString(m Byte, "x2")
myStr = ArrayToString(m Byte)

Debug.WriteLine (myStr)
mByte = Nothing
'mByte = StringToArray(m yStr,
Globalization.N umberStyles.All owHexSpecifier)
mByte = StringToArray(m yStr)

End Sub

Hope this helps
Jay

Re: How to convert byte() to string, and from string back to byte()

Thanks. I found i need to use this one since the array comes from a
differenct type of encoding used in an encryption function and I found that
I use the other methods above it actually chances the data so it can't be
restored.

Thanks to ALL.
