Zip library for Windows Phone 7

问题

I'm downloading zip files and place them in isolated storage on Windows Phone 7. Is there an API or library that allows me to unzip the files?

回答1:

You can use SharpZipLib to decompress downloaded zip files. I have used this version (binaries downloaded from Codeplex) in my applications without any issues, however, I would recommend download the source and compiling it yourself. The decompressed file can be read into a string -

// check for magic numbers
if (data.Length > 2 && (data[0] == 31 && data[1] == 139))
{
   using (var ms = new MemoryStream(data))
   using (var gzip = new GZipInputStream(ms))
   using (var reader = new StreamReader(gzip))
   {
      fileContents = reader.ReadToEnd();
   }
}         

data is an array of bytes which holds the zip file read from IsolatedStorage. fileContents is a string that holds the contents of the decompressed file.

SharpZipLib is under GNU license and is therefore not allowed by the Microsoft app store.
