Network Stream blocked!

[alphador]

Hello!

I'm doing a client server application via TCP/IP and I need to transfer files: while the client transfers chunks of data, it waits for an acknowledge from the server, by doing this:

netStream.Read(data, 0, 1);

It means that it waits 1 byte from the server, then it goes on.
However if for some reason the server does not send the acknowledge to the client, this instruction blocks the application...

Is there another way to get an acknowledge without the risk of freezing the thread/application ?

Thanks

It sounds like what you're looking for is the BeginRead method. It does everything the Read function does, except it uses IAsyncResult interface. MSDN has a write up at

http://msdn2.microsoft.com/en-us/library/system.net.sockets.networkstream.beginread(VS.71).aspx

Thanks, I will try that.
Still wandering though what is the

allDone.WaitOne();

instruction in that link. That is, I don't get where the "allDone" comes from...

hmmm...I didn't look that closely at the code example they gave. The allDone object is a AutoResetEvent object. It lives within the System.Threading namespace.
