c# extract zip file with directory

I'm using c# fw4.5. I have a simple code extracting a zip file.

foreach(ZipArchiveEntry entry in z.entries) //z is a zip file open in ZipArchiveMode.Read
{
        entry.ExtractToFile(entry.FullName);
}

The zip file have a directory inside it and all files are inside that directory. When I look at the z.Entries I see its an array which place [0] is only the directory and [1],[2],[3] are files. But when its try to do:

entry.ExtractToFile(entry.FullName);

On the first entry, I get an error: "The filename, directory name or volume label syntax is incorrect".

I can't seems to find out whats wrong. Do I need to anything also for it to open the directory? Maybe because the entry is a directory only the "ExtractToFile(entry.FullName)" can't work?

Thanks in advanced.

In addition to Tonkleton's answer I would suggest that you use a third-party compression library since ZipArchive is not supported for framework versions before the .Net 4.5 framework, might I suggest DotNetZip as mentioned in other questions regarding compression in earlier frameworks on StackOverflow.

Replace your paths:

void Main()
{
    var zipPath = @"\\ai-vmdc1\RedirectedFolders\jlambert\Downloads\cscie33chap1and2.zip";
    var  extractPath = @"c:\Temp\extract";

    using (ZipArchive z = ZipFile.OpenRead(zipPath))
    {
        foreach(ZipArchiveEntry entry in z.Entries) //z is a zip file open in ZipArchiveMode.Read
        {
            entry.ExtractToFile(Path.Combine(extractPath, entry.FullName), true);
        }
    } 
}

According to this MSDN article, the ExtractToFile method expects a path to a file (with an extension) and will throw an ArgumentException if a directory is specified.

Since the first entry in the archive is a directory and you are using its name as the argument, that is why you are having this issue.

Look into the related ExtractToDirectory method, which is used like so:

ZipFile.ExtractToDirectory(@"c:\zip\archive.zip", @"c:\extract\");
