winforms - VB.Net 4.6 using Zipfile -

i have been searching site while , cant seem find solution. trying to use zipfile zip pdfs directory whenever type using zip zipfile = new zipfile errors saying:

'using' operand of type 'system.io.compression.zipfile' must implement 'system.idisposable'

'system.io.compression.zipfile' has no constructors.

after searching through site found out had add references did added: system.io.compression , system.io.compression.filesystem made sure using correct .net framework , using .net 4.6 in vs 2013. stuck on do, wanted zip several files folder, can't use zipfile. information on appreciated.

the code using is:

dim ziptocreate string = "ex1.zip" dim directorytozip string = "c:\temp" using zip zipfile = new zipfile     dim filenames string() = system.io.directory.getfiles(directorytozip)     dim filename string     each filename in filenames         zip.addfile(filename)     next     zip.save(ziptocreate) end using 

from example -> how zip files in vb.net 2005

you mixing 2 different "zipfile" apis.

the sample code copied expects have reference dotnetzip library use zipfile class, not part of .net framework.

the .net framework has zipfile class, different api, , that's 1 code referring to.

pick 1 want use , make sure reference correct libraries , read appropriate documentation code properly.
