Question

Lets say that I use HttpWebRequest to call a web-service written in python and that service returns a XML file. Lets assume that it takes 10 seconds to download the data.

 HttpWebResponse response = (HttpWebResponse)req.GetResponse();

 if(allDate100%Transfered)
 MsgBox.show("u can now CUT your cable. All data is there!!!");

Are there any property to check if everything have been transferred?

Because I want to proceed and for example read the received data into a string, but only when all data have been downloaded successfully.

Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
String xml = reader.ReadToEnd();

Do I get any message or sign from the webservice, which tells me that all data is really there and I do not need the connection anymore?

Edit: The problem is stil there. I get different answers and they contradict each other.

Answer 1

request.GetResponse() is synchronous which means that it doesn’t return until all data have been downloaded.

The documentation of request.GetResponse() states that WebException is thrown if:

• Abort was previously called.
• The time-out period for the request expired.
• An error occurred while processing the request.

Which means that everything went OK if no exception was thrown.
