C# and ObjectInputStream in Java via Socket!

Question

I hava a socket server is written in Java and the client is written in C#.

If I use the InputStream in a socket server, I can get the request from the Client. My code as below:

InputStream myIN = sock.getInputStream();
byte[] b = new byte[10];
int revByte = myIN.read(b);

but if I use the ObjectInputStream in the socket server, I can not receive any request from the Client.
The exception is: "java.io.StreamCorruptedException: invalid stream header"
My code as below:

in = new ObjectInputStream( sock.getInputStream() );
Object value = in.readObject();

So, my question is: can C# client work with ObjectInputStream in Java via socket?

Any helping will be appreciate.
Thanks so much,
Dan

Answer 1

ObjectInputStream expects a data stream containing serialized representations of java objects... theoretically c# could encode it's objects in java's serialization format, but it wouldn't be pretty.

Answer 2

jspcal is right: Maybe with this classes?

Java Server

ServerSocket ss=new ServerSocket(1800); Socket s=ss.accept(); System.out.println("Client Accepted"); BufferedReader br=new BufferedReader(new InputStreamReader(s.getInputStream())); System.out.println(br.readLine()); PrintWriter wr=new PrintWriter(new OutputStreamWriter(s.getOutputStream()),true); wr.println("Welcome to Socket Programming"); }catch(Exception e){System.out.println(e);}

C# Client:

TcpClient tc=new TcpClient("server",1800);// in the place of server, enter your java server's hostname or Ip Console.WriteLine("Server invoked"); NetworkStream ns=tc.GetStream(); StreamWriter sw=new StreamWriter(ns); sw.WriteLine("My name is Pramod.A"); sw.Flush(); StreamReader sr=new StreamReader(ns); Console.WriteLine(sr.ReadLine()); }catch(Exception e){Console.WriteLine(e);}
