trouble extracting from zip file using SharpZipLib

[gib99]

Hello,

I'm using SharpZipLib and I'm trying to understand why my files are not extracting to the target directory that I specify.

I have a zip file under C:\tmp\TestData\. I want to extract it to C:\tmp\TestData\temp\. Instead, it extracts it to C:\tmp\TestData\temp\tmp\TestData\. That is, it seems to be taking the original path which the zip file is under and tacking that onto the target directory that I specify. Why is it doing this?

Here's my code:

        private bool UnzipAcmZipFile(string pathAndName)
        {
            if (!File.Exists(pathAndName) ||
                !pathAndName.EndsWith(acmZipExtensionStr))
            {
                return false;
            }

            FastZip fastZip = new FastZip();
            fastZip.ExtractZip(pathAndName, "C:\\tmp\\TestData\\temp\\", string.Empty);

            return true;
        }

Perhaps because the ZIP file itself contains the compressed files/folders within a tmp folder.

What do you see if you just open the ZIP file within a ZIP-processing application? Does it show the files within the tmp (and perhaps subsidiary Testdata) folders?

Here's how I was zipping the files:

ZipFile zipfile = ZipFile.Create(pathAndNameExtStripped + acmZipExtensionStr);
zipfile.BeginUpdate();
zipfile.Add(pathAndFileName);
zipfile.CommitUpdate();
zipfile.Close();

Here's how I'm zipping the files now:

ZipFile zipfile = ZipFile.Create(pathAndNameExtStripped + acmZipExtensionStr);
zipfile.BeginUpdate();
zipfile.Add(pathAndFileName, fileNameWithoutPath);
zipfile.CommitUpdate();
zipfile.Close();

This seems to work. By adding fileNameWithoutPath as the second argument to zipfile.Add(...) (the entryName), I'm actually able to name the entry (the file) which seems to determine how it gets unzipped (I'm assuming the default name included the full path).
