Exception: EOF in Header occuring while extracting zip from isolated storage

Question

I have generated a zip using streamwriter in isolated storage named temp.zip and return its bytes in stream for extraction. Please find the code as below

stream = LoadZipFromLocalFolder(filename);
using (IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication())
{
    using (var zipStream = new ZipInputStream(stream))
    {
        ZipEntry entry;
        //EOF in header occuring on below line
        while ((entry = zipStream.GetNextEntry()) != null)
        {
            string directoryName = Path.GetDirectoryName(entry.Name);
            string fileName = Path.GetFileName(entry.Name);

            if (!string.IsNullOrEmpty(fileName))
            {
                if (!isoStore.DirectoryExists(directoryName))
                {
                    isoStore.CreateDirectory(directoryName);
                }

                string fileFullPath = Path.Combine(directoryName, fileName);
                Debug.WriteLine(fileFullPath);
                using (var streamWriter = new BinaryWriter(new IsolatedStorageFileStream(fileFullPath, FileMode.Create, FileAccess.Write, FileShare.Write, isoStore)))
                {
                    var buffer = new byte[2048];
                    int size;
                    while ((size = zipStream.Read(buffer, 0, buffer.Length)) > 0)
                    {
                        streamWriter.Write(buffer, 0, size);
                    }
                    streamWriter.Close();
                    streamWriter.Dispose();
                }
            }
        }
    }
}

When I created temp.zip, it has ReadWrite,Share permissions and also I tried to unzip manually, then its getting extracted properly without causing any error, but in code its showing error EOF in HEADER.

Please help..

Thanks

I solved the EOF in header by using just a simple code as follows :

Stream.Position =0;

Hope it helps to some one.

Thanks.
