Dear All,

Here I came with a trouble. I have a zip file in my server. I am not suppose to download that zip file to extract its contents.

Eg., "test.zip" contains folder "test" with files "test1.jpg" & "test2.jpg".

I should not download "test.zip" folder but I should find files inside test folder placed inside that "test.zip".

If files available then I should download that jpg files and place it in my application path.

If this question is clear please help me to get out from this problem. I tried in net but I nothing to help me. Please help ASAP.

My preferred and simple way ( as far I know) is through DotNetZip.
Through this you not only can read but also can manipulate files like add file, delete file etc.

However, since .Net 4.5 there a is method called ZipFile.OpenRead() through which you can read files.
Something like -

C#

string zipPath = @"c:\example\start.zip";
            using (ZipArchive archive = ZipFile.OpenRead(zipPath))
            {
                foreach (ZipArchiveEntry entry in archive.Entries)
                {
                    Response.WriteLine(entry.FullName);
                }
            }

Hope, it helps :)

Solution 1

Start by looking at ZSharpLib[^] - it's pretty flexible about where the file is.

However, if the zip file is on a server, you will need direct access to the folder containing the file, and at least read permissions on that folder.
