Hows it going everyone. Right now I am working on a project with VS2008 that parses directory and subdirectories and lists all filenames/paths/size/etc. This is working correctly, but I also need to parse the contents of zip files without actually unzipping them. What would be the easiest method to return the information on the files in a zip file? (Filename, Size, etc). Heres the code that I currently have to parse directories and subdirectories.

Sub Parse(ByVal ThisFolder As String)
        FSO = New Scripting.FileSystemObject
        Dim soFolder As Folder
        Dim soFile As File
        Dim soFolders As Folders


        soFolder = FSO.GetFolder(ThisFolder)

        ' Files in this directory

        For Each soFile In soFolder.Files
            ' TestdbDataSet.Table1.Rows.Add(CStr(ThisFolder), CStr(soFile.Name), CStr(soFile.Type), CStr(soFile.Size))
            Table1TableAdapter.Insert(CStr(ThisFolder), CStr(soFile.Name), CStr(soFile.Type), CStr(soFile.Size))
        Next soFile

        ' Recurse Subdirectories
        soFolders = soFolder.SubFolders ' parses subfolders

        For Each soFolder In soFolders
            Parse(soFolder.Path)
        Next soFolder

        soFolders = Nothing
        soFolder = Nothing
        soFile = Nothing


    End Sub

Is this library able to just list the files? I was reading over it and mostly only saw that it zipped and unzipped files, etc.

Can anyone help me convert this VB6 code to get zip filenames to .Net?

Dont know if it worked but I had a go. THis is pretty much the same code in vb.net without errors.

Hmm, getting a directory not found error when it gets here:

objFolder = objFSO.GetFolder(strTempFolder)
strDest = "The following files are found in '" & strZipFile & "':" & vbLf
strDestTarget = "The following special files are found in '" & strZipFile & "':" & vbLf
