Remove Folder in ZIP Dotnetzip

VB

I want to remove a folder (META-INF) from a .ZIP file, I have tried to do this before but failed. Does anyone have a code I can use to remove a folder?

I REALLY NEED HELP! I have until the 10th to release my program as planned, and I don't want to delay it again!

EDIT:
I have tried to search numerous times! Thats the problem. I found NO code that could help and I tried to do it on my own and got an error saying 'Entry does not exist'...

Here's a code:

Dim selection = zip1.SelectEntries("*.*", "META-INF")
For x = selection.Count - 1 To 0 Step -1
	Dim e As ZipEntry = selection(x)
	zip.RemoveEntry(e.FileName)
Next

EDIT 2:
Well now I have the code and no error comes up but It still does not delete it... Can anyone point out where I went wrong here?

Dim Threshold As New String("META-INF")
Using zip As ZipFile = ZipFile.Read("C:\Users\" + GetUserName + "\AppData\Roaming\MCqTools\Mod_p\editor.zip")
    Dim MarkedEntries As New System.Collections.Generic.List(Of ZipEntry)
    Dim e As ZipEntry
    For Each e In zip
        If (e.IsDirectory = Threshold) Then
            MarkedEntries.Add(e)
        End If
    Next
    Dim folderMETA As ZipEntry
    For Each zombie In MarkedEntries
        zip.RemoveEntry(folderMETA)
    Next
    zip.Save()
End Using
