(.NET Core C#) Download a Zip from a URL and OpenBd. (No .zip file is created)Demonstrates how to download a .zip from a URL, opens the Zip, and gets the contents of a file. No file is ever written.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.Http http = new Chilkat.Http(); Chilkat.BinData bd = new Chilkat.BinData(); // This URL is valid and can be tested... bool success = http.QuickGetBd("http://chilkatdownload.com/example_data/hamlet.zip",bd); if (http.LastMethodSuccess != true) { Debug.WriteLine(http.LastErrorText); return; } Chilkat.Zip zip = new Chilkat.Zip(); // Open the zip from the bytes contained in bd. success = zip.OpenBd(bd); if (success == false) { Debug.WriteLine(zip.LastErrorText); return; } // Get the entry for the file we want.. Chilkat.ZipEntry entry = zip.GetEntryByName("hamlet.xml"); if (zip.LastMethodSuccess != true) { Debug.WriteLine(zip.LastErrorText); return; } // Convert all line endings to CRLF (if needed) int lineEndingBehavior = 2; string xmlStr = entry.UnzipToString(lineEndingBehavior,"utf-8"); if (entry.LastMethodSuccess != true) { Debug.WriteLine(entry.LastErrorText); return; } // The XML in this case is about 274K, so let's just examine the last 20 lines... Chilkat.StringBuilder sb = new Chilkat.StringBuilder(); sb.Append(xmlStr); Debug.WriteLine(sb.LastNLines(20,true)); |
