Вы можете сделать это с помощью SharpZipLib для Silverlight / Windows Phone 7.
Следующий код основан на этом примере и демонстрирует, как архивировать корневую папку, включая подпапки и файлы.
Краткий обзор:
button1_Click готовит несколько фиктивных папок и файлов для подтверждения концепции: папка root , содержащая файл, и две подпапки , каждая из которых также содержит файл, затем вызывает CreateZip сжать все дерево каталогов, начиная с root CreateZip готовит zip-файл и запускает рекурсивное сжатие папок, вызывая CompressFolderCompressFolder добавляет все файлы в данном каталоге в zip-файл и возвращается в подкаталоги
код:

using ICSharpCode.SharpZipLib.Zip;
using ICSharpCode.SharpZipLib.Core;
using System.Text;
// Recurses down the folder structure
//
private void CompressFolder(string path, ZipOutputStream zipStream, int folderOffset, IsolatedStorageFile isf)
{
string[] files = isf.GetFileNames(System.IO.Path.Combine(path, "*.*"));
foreach (string filename in files)
{
string filenameWithPath = System.IO.Path.Combine(path, filename);
string entryName = filenameWithPath.Substring(folderOffset); // Makes the name in zip based on the folder
entryName = ZipEntry.CleanName(entryName); // Removes drive from name and fixes slash direction
ZipEntry newEntry = new ZipEntry(entryName);
newEntry.DateTime = isf.GetLastWriteTime(filenameWithPath).DateTime; // Note the zip format stores 2 second granularity
// To permit the zip to be unpacked by built-in extractor in WinXP and Server2003, WinZip 8, Java, and other older code,
// you need to do one of the following: Specify UseZip64.Off, or set the Size.
// If the file may be bigger than 4GB, or you do not need WinXP built-in compatibility, you do not need either,
// but the zip will be in Zip64 format which not all utilities can understand.

zipStream.Password = password; // optional. Null is the same as not setting.
// This setting will strip the leading part of the folder path in the entries, to
// make the entries relative to the starting folder.
// To include the full path for each entry up to the drive root, assign folderOffset = 0.
// int folderOffset = folderName.Length + (folderName.EndsWith("\\") ? 0 : 1); // hu: currently not used for WP7 sample
