In WPF and Silverlight applications, data compression is especially useful when transferring between client and server, and also when storing application data in isolated storage (which is limited to 1MB by default). These classes are divided into three levels:</p> <p> </p> <table cellspacing="0" cellpadding="0" border="1"> <tbody> <tr> <td valign="top" width="70"> <p><strong>Level</strong></p> </td> <td valign="top" width="156"> <p><strong>Main Classes</strong></p> </td> <td valign="top" width="341"> <p><strong>Description</strong></p> </td> </tr> <tr> <td valign="top" width="70"> <p>High</p> </td> <td valign="top" width="156"> <p><a href="C1.WPF.Zip.4~C1.C1Zip.C1ZipFile.html">C1ZipFile</a>, <a href="C1.WPF.Zip.4~C1.C1Zip.C1ZipEntry.html">C1ZipEntry</a>, <a href="C1.WPF.Zip.4~C1.C1Zip.C1ZipEntryCollection.html">C1ZipEntryCollection</a></p> </td> <td valign="top" width="341"> <p>Use these classes to create, open, and manage Zip files.
