I'm coding in VB.NET 2005 with a Using block and a StreamWriter as in
Using strWrite As New IO.StreamWriter (fileName, True)
strWrite.WriteL ine(Now & vbTab & cLineToWrite)
End Using
Should I explicitly call the Close method on the StreamWriter or is the
object closed and disposed when the Using block is exited?
Thanks for your insights.

As far as i know, "End Using" statement is enough to dispose resource.
No need to use close method in that case.

It is closed when the using block exits - even if there is an error,
that is the point of a using block. Calling close explicitly, just makes
for redundant code.

Not necessarially. You may be done using the object, but not have hit the
"End Using" yet. With a resource like a file (that others may need to
access), it may be a good idea to call close() explicitly as soon as you are
done using it and use "End Using" as a fail-safe.

IMHO, that would be a rare case, and one that I would suggest is
probably in need of refactoring. In general, with files the rule is
get in, get what you need, and get out. No, in general, I would stand
by my original post.

IMHO, I don't think it's as rare as you may think. If I'm going to need to
re-open the stream after I close it, I wouldn't want it disposed yet, but I
would want it closed while I'm not using it.

System.IO.StreamWriter Close or Flush method to shut down the computer in
such a way that just part of the file is written? or an empty file is
written? Also if the Close or Flush is to a streamwriter writing to a
network share, is it possible for the network to go down in such a way that
the tartet file is only partialy written? or are there some kind of check
sums to prevent this.

if System.IO.StreamWriter write throws an exception, is there anyway to
close the System.IO.StreamWriter object? it seems to stay open when this
happens then future attempts to write to that same path fail because it says
its in use by another process.

In the following example, is it necessary to close the FileStream object as

swFromFile.Write(textToAdd);
swFromFile.Flush();

Hi,
In the MSDN the sample doesn't use the close() method. But I know that
in most languages you do need to use the close() method after reading
