I am sending a stream to methods to write on, and in those methods I am using a binary reader/wrtier. When the reader/writer gets disposed, either by using or just when it is not referenced, is the stream closed as well??

I'm running into an issue where reading from a HttpResponseStream fails because the StreamReader that I'm wrapping around in reads faster that the Response Stream gets the actual response. I'm retrieving a reasonably small sized file (around 60k) but the Parser which processes the response into an actual object fails because it hits an ...

On one computer we can read data from the text file even after it has been deleted or replaced with a different text file - the File.Exists call reports that the file exists even when it doesn't in Windows Explorer. However, on another computer this behaviou...

Hello I'm reading from a Socket's InputStream. Because I'm parsing the incoming data on the fly, I'm required to read character by character.
