Dec 22, 2010I've been using the following code to download a text file from the web. It only downloads the first 100,000 bytes of the file which is no good if the file is big. The size of the file I'm downloading can vary from day to day, so I need to be able to download a text file of any size.

VS 2008 What Does This Line Exactly Do - I = Stream.Read(bytes, 0, Bytes.Length)
Dec 28, 2010What exactly does this line do?
i = stream.Read(bytes, 0, bytes.Length)
Does it read the entire message string sent by the client? I have a line to write to the stream later in the code and that does not seem to be sending anything back to the client, although the code around is excuting.
i = stream.Read(bytes, 0, bytes.Length)
While (i <> 0)

Download A File With A Download Timeout?
Feb 4, 2010I want to download thousands of files from the web and save them locally. What is the most efficient way? It is important the failures timeout within 10 seconds.
Is there a better way to stream one stream into another? Maybe a smaller buffer, like 1024 bytes at a time, is more efficient for large files?

C# - Get The Bytes From A Stream?
Jun 4, 2012I'm writing a VB.net application (but you can answer in C# if you want, no problem) that uses a 3rd party .NET library. In particular, one method in this library takes an IO.Stream as input (among other things) and writes the results of its processing to said stream. My problem is that the method CLOSES the stream after writing to it, so I can't read back the data that it wrote in it!To be more specific: it works, of course, if the stream is a FIeStream , since it writes the data on disk, but what if I want to read the data directly to memory? I tried using a MemoryStream, but as I said, when the method returns the stream is already closed, and I can't read back anything from it.

.net - Convert A Single Into 8 Bytes?
Jan 6, 2010I have a single that might have a decimal place but might not. I have to put the digit before the decimal into the first 4 bytes and the digit after in the next 4 bytes.
So 1.1 would be 01-00-00-00-01-00-00-00
or 2.1 would be 02-00-00-00-01-00-00-00
or 1 would be 01-00-00-00-00-00-00-00
The digit before the decimal point is stored like an integer in bytes the same with the digit after the point. So 1.1 gets split into 1 and 1 and then stored as 2 DWORDS: 01000000 and 01000000
