Hi,

I am in trouble of extracting a specific file from a .zip file.
I want to extract one known file from a.zip file. I know the file(known.txt) exist in that .zip(test.zip) file, so i just want to extract the file to temporary location without any search or going through the entire zip.

It would be great if someone help me on this one.

Hi Afsal,

Thank you so much for getting back.

I am using MS VS 2010 V10.0 and MS .NET Framework V4.5.50709P1Rel.

When add above code in my method it says ZipArchive couldn't found or missing assembly.

Believe ZipArchive is belongs to System.IO.Compression.FileSystem, but I can't find the dll in the project reference list.

So what I did then I have downloaded the dll for System.IO.Compression.FileSystem and added as reference into the project, however the same can't be accessible using in the project itself.

Can you please guide me here ? Many thanks.

Regards, Surya

You can browse to C:\Windows\Microsoft.NET\Framework\v4.0.30319\ and add System.IO.Compression.dll and System.IO.Compression.FileSystem.dll file as reference
