XmlTextReader and NetworkStream

[Stelrad Doulton]

Hi all,

I am writting a Jabber-esque client-server application and have run into an
issue with the XmlTextReader constructor when passing a NetworkStream - It
hangs forever, apparently this is an issue with SP1.

Anyway I have the code below as a work around (using bool keepalives as it
must run on the CF):

while(keepAlive)

{

//do the blocking read on one thread

NetworkStream readStream = new NetworkStream(this.socket, false);

while(!readStream.DataAvailable && keepAlive)

{

Thread.Sleep(100);

}
if(!keepAlive)

break;

MemoryStream memStream = new MemoryStream();

byte[] buffer = new byte[256];

int bytes = 0;

do

{

bytes = readStream.Read(buffer, 0, buffer.Length);

memStream.Write(buffer, 0, bytes);

}while(readStream.DataAvailable);
memStream.Seek(0, SeekOrigin.Begin);

if(DataAvailable != null)

DataAvailable(memStream);

}

My grasp of TCP/IP is still tenuous but I am concerned that a very large
file coming in very slowly could be a problem. Could this code empty the
underlying Socket buffer and return an incomplete stream?

Thanks
