C# ASP.NET 3.5: zip more than 65535 dynamic files with SharpZipLib -

i'm trying zip 100 000 dynamic files, , on console app can without problem, on web app appears it's @ kind impossible.

console

static void main(string[] args) {     using (zipoutputstream zipoutputstream = new zipoutputstream(file.create("test.zip")))     {         zipoutputstream.setlevel(0);         (long = 1; < 100000; i++)         {             string txt = "file " + i.tostring();             byte[] bytes = system.text.encoding.utf8.getbytes(txt);             using (memorystream ms = new memorystream(bytes))             {                 zipentry entry =                     new zipentry(zipentry.cleanname(i.tostring() + ".txt"))                     {                         datetime = datetime.now,                         compressionmethod = compressionmethod.stored,                         size = bytes.length                     };                 zipoutputstream.putnextentry(entry);                 byte[] buffer = new byte[1024];                 icsharpcode.sharpziplib.core.streamutils.copy(ms, zipoutputstream, buffer);                 console.writeline(i.tostring());             }         }     } } 

web

protected void page_load(object sender, eventargs e) {     response.clear();     response.clearheaders();     response.cache.setcacheability(httpcacheability.nocache);     response.contenttype = "application/octet-stream";     response.addheader("content-disposition", "attachment; filename=" + "file.zip");      using (zipoutputstream zipoutputstream = new zipoutputstream(response.outputstream))     {         zipoutputstream.setlevel(0);         (long = 1; < 100000; i++)         {             string txt = "file " + i.tostring();             byte[] bytes = system.text.encoding.utf8.getbytes(txt);             using (memorystream ms = new memorystream(bytes))             {                 zipentry entry =                     new zipentry(zipentry.cleanname(i.tostring() + ".txt"))                     {                         datetime = datetime.now,                         compressionmethod = compressionmethod.stored,                         size = bytes.length                     };                 zipoutputstream.putnextentry(entry);                 byte[] buffer = new byte[1024];                 icsharpcode.sharpziplib.core.streamutils.copy(ms, zipoutputstream, buffer);                 response.flush();             }         }     }     response.flush();     response.end(); } 

so far know there should zip file amount limit 65535 files on console not matter. know can use zipoutputstream.usezip64 = usezip64.on not change anything. there way solve issue ?

edit: forgot mention file created on unzipping it's broken
