The given path's format is not supported.

I'm trying out DotNetZip. Seems good but can't get it to work, even the simplest demo;  see code below and errors....tries various combinations but didn't work.

Crashes at zip.Save(). See for folders I've tried to save at.

Thanks in advance for help on this
Dim ZipToCreate As String = ""
        'The given path's format is not supported. 
        'Dim DirectoryToZip As String = Server.MapPath("~/App_Data/TextFiles")
        'Dim DirectoryToZip As String = Server.MapPath("~/App_Data/TextFiles/")
        'Dim DirectoryToZip As String = "C:\"
        'Dim DirectoryToZip As String = "C:\\"
        'Dim DirectoryToZip As String = "C:\temp"
        'Dim DirectoryToZip As String = "C:\temp\"
        'Dim DirectoryToZip As String = "C:\\temp\\"
        'Could not find a part of the path 'c:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ddddddddddd'. 
        'Dim DirectoryToZip As String = "ddddddddddd"
        'Could not find a part of the path 'C:\doesn't exist'. 
        'Dim DirectoryToZip As String = "C:\\doesn't exist\\"
        Using zip As ZipFile = New ZipFile(ZipToCreate)
            Dim filenames As String() = System.IO.Directory.GetFiles(DirectoryToZip)
            Dim filename As String
            For Each filename In filenames
                Console.WriteLine("Adding {0}...", filename)
        End Using

even a simple example like this isn't working :-(

 Using zip As ZipFile = New ZipFile("")
            zip.AddFile("C:\a folder\test.xml")
        End Using

It could change depending of your config, but must of the times it<s IUSR_ComputerName
