Serialization Question

[Tiraman :-\)]

Hi,

i have a StreamWriter that hold a System.Net.Sockets.NetwrokStream
and the StreamWriter Object Hold An ArrayList which
i would like to Serialize And Send it back to the client via the
StreamWriter.Flush()
Dim writer As New IO.StreamWriter(System.Net.Sockets.TcpClient.GetSt ream)

writer.Write(myArray)

Dim binF As New BinaryFormatter

how can i Serialize it ?

Thanks!

Is this what you want?

Dim binF As New BinaryFormatter
Dim writer As New IO.StreamWriter(System.Net.Sockets.TcpClient.GetSt ream)
binF.Serialize(writer, myArray)

Lance

[Tiraman :-\)]

yes,

but this what i tried and it didn't work for me since the
BinaryFormatter.Serialize doesn't accept a StreamWriter :)

do you know other way to implement this kind of operation ?

Hi Tiraman,

This sample I once made should do the job for you.

I hope this helps?

Hi Cor ,

it is a good example but it is not cover my problem.

I have a NetworkStream Which I m getting into the StreamWriter which i would
like to serialize.

how can i do that ?

Thanks!

Dim writer As New IO.StreamWriter(System.Net.Sockets.TcpClient.GetSt ream)

Thanks!

Yes and what is wrong with it the sample first serialize and than deserilize
in one sample.

You have to use serialize, stream, and deserialize, however that was not the
problem I thought?

Cor

[Tiraman :-\)]

Hello Cor,

I m not sure that i understood you so here is my example and i will be happy
if you let me know where , what and why is the problem :-)
Private client As TcpClient

Sub xxx(ByVal obj As Object)

SyncLock client.GetStream
Dim sw As New IO.StreamWriter(client.GetStream)

sw.Write(CType(obj,ArrayList))

Dim bf As New BinaryFormatter

bf.Serialize(sw, obj)
sw.Flush()
sw.Close()

End SyncLock

End Sub

Thanks!

Tiraman this is the serialization part in my code

Dim bf As New Runtime.Serialization.Formatters.Binary.BinaryForm atter
dim mem As New IO.MemoryStream
bf.Serialize(mem, arraylst)
Dim myString as STring = Convert.ToBase64String(mem.ToArray())

When I look at your code I see

Private client As TcpClient Sub xxx(ByVal myArray As as Arraylist) ' passing it as arraylist saves
casting Dim sw As New IO.StreamWriter(client.GetStream)
Dim bf As New BinaryFormatter dim mem As New IO.MemoryStream
bf.Serialize(mem, myArray)
Dim myString as String =
Convert.ToBase64String(mem.ToArray())
sw.Write(myString) sw.Flush()
sw.Close()

Than I think it can be something like this, not tried,

I hope this helps?

Now the Serialize ok but i m getting the following error in the Deserialize
method.

Hi Cor,
Once Again Thanks for your help.

now every thing working fine but i still have one problem.
with the Convert.FromBase64String i can work with very small strings and i
would like to
work with more then 64 bit.

any idea ?

Thanks
