I have a class containing string variables, hashtables..I managed to
serialize it into a memory stream instead of file stream. Would like to know
how can I convert the byte array to string. I tried using
encoding.default.getstring but the output is an empty string..(:..damn!
partial code example that copied for microsoft for testing purpose:
Dim addresses As New Hashtable
addresses.Add("Jeff", "123 Main Street, Redmond, WA 98052")
addresses.Add("Fred", "987 Pine Road, Phila., PA 19116")
addresses.Add("Mary", "PO Box 112233, Palo Alto, CA 94301")
Dim mstrm As New MemoryStream
Dim formatter As New BinaryFormatter
formatter.Serialize(mstrm, addresses)
dim str as string = encoding.default.getstring(mstrm.toarray)
Please advise. 6 2486
Red Devil,
The nices one I know
\\\ from a message from Tom Shelton
Private Function SerializeFontObject(ByVal fnt As Font) As String
Dim bf As New BinaryFormatter
Dim mem As New MemoryStream
Try
bf.Serialize(mem, fnt)
Return Convert.ToBase64String(mem.ToArray())
Catch
Return String.Empty
Finally
mem.Close()
End Try
End Function
Private Function DeserializeFontObject(ByVal fnt As String) As Font
Dim bf As New BinaryFormatter
Dim mem As New MemoryStream(Convert.FromBase64String(fnt))
Try
Return DirectCast(bf.Deserialize(mem), Font)
Finally
If Not mem Is Nothing Then
mem.Close()
End If
End Try
End Function
///
I hope this helps a little bit?

Cor,
Another problem occurred. It doesn't happen all time thou. I did a load test
using load runner. On an occassion, the serialized string is incomplete.
Encounter such problem before?
The data is sent from client to server via socket.

Red Devil,
That is the part I don't like.
However set a message in the newsgroup
microsoft.public.dotnet.languages.vb
There this probem is often handled. Although you can have the same results
here.
So crossposting to both newsgroups with your problem.(one message to both in
one time) will probably give you the best results.

Cor,
What do you mean by 'That is the part I don't like.'?

Red Devil, The data is sent from client to server via socket.
I don't like it being busy in that area, I never did, that is all.
