  StreamWriter & File being used after copy.

  Sep 19, 2011 08:19 AM|LINK

  Hello everybody,

  I have a sub that copies and renames a file:

  My.Computer.FileSystem.CopyFile(sourcefile, destfile)

  And since here everything is working fine, the file is copied succesfully!!!

  The problem comes out when, after, in another sub, I try to write something inside the file copied because for vb the file is still being used!!!

  So if I call:

          sw = New StreamWriter(destfile)

  I receive the error.

  I can't kill the process because the process that's keeping the file in use is my app; what the simplest way to "close" the file?

  Many thanks in advance for your help.

  Regards,
  Lybra

  you should be using this to dispose the object implicitly.

  using (StreamWriter writer = new StreamWriter("important.txt"))
  	{
  	    writer.Write("Word ");
  	    writer.WriteLine("word 2");
  	    writer.WriteLine("Line");
  	}

  Normal people believe that if it ain't broke, don't fix it. Engineers believe that if it ain't broke, it doesn't have enough features yet.

  sw.flush();

  sw.close();

  sw.dispose();

  usually close or dispose is enough.
