Cannot access closed file

Mar 17, 2009 at 1:44 PM
The following highlighted line is generating error "Cannot access closed file"

public static void UpdatePageNode(XmlDocument objXmlDocument, string filename, ref ZipFile ZipCPDFile)
            using (MemoryStream ms = new MemoryStream())
                objXmlDocument = null;

                ms.Seek(0, SeekOrigin.Begin);
                ZipCPDFile.UpdateFileStream(filename, "", ms);

I am guessing that the ZipCPDFile is a ZipFile instance that you have initialized somewhere else?

Have you added other entries to this ZipFile instance?

The rule is this:  if you call ZipFile.AddFile() (or AddItem, or UpdateItem or UpdateFile) , then the file specified in the call must be available at the time you call ZipFile.Save(). 

If I do this:
  using (var zip = new ZipFile())

...then I will surely get a "file does not exist" exception.

Have you done something like this?

If not, then can you produce a succint program that reproduces the problem you are seeing? Or, failing that, can you post the stack trace? I'll see what I can do.
