Error unzipping in WCF

[Alexander]

Hello


I'm trying to create a ZIP file from Silverlight with a list of JSON data and compresses well. 
The problem is to receive it in the server because I have no library Telerik receive the Zip to 
extract and process the result. The library I am using is IonicZip to receive the result but 
I get error trying to read the MemoryStream. Is there a library for ASP.net Telerik decompress 
the ZIP file

Code in Silverlight:
MemoryStream memoryStream = new MemoryStream();
ZipCompression method = ZipCompression.Default;
Telerik.Windows.Zip.ZipOutputStream zipOutputStream = new Telerik.Windows.Zip.ZipOutputStream(memoryStream, method);
StreamWriter writer = new StreamWriter(zipOutputStream);
writer.Write(listSave.ToJSON());
writer.Flush();
ServicesClient context = new ServicesClient();
context.SetZipFileAsync( Convert.ToBase64String(memoryStream.ToArray()));

Code in WCF:
public void SetZipFile(string _parameter)
     {
         if (!string.IsNullOrWhiteSpace(_parameter))
         {
             var info = Convert.FromBase64String(_parameter);
             MemoryStream stream = new MemoryStream(info);
             string dataList = string.Empty;
             MemoryStream output = new MemoryStream();
             StreamReader read = new StreamReader(output);
             using (ZipFile zip = ZipFile.Read(stream))
             {
                 ZipEntry item = zip[0];
                 item.Extract(output);
                 output.Seek(0, SeekOrigin.Begin);
                 dataList = read.ReadToEnd();
             }
         }
     }

Hi Alexander,

In the RadControls for WPF suite of controls, you can get the Telerik.Windows.Zip.dll which is a plain .Net assembly and you can reference it in your WebApplication. Give this a try and let us know if you need more information.

All the best,
