(Mono C#) Set Entry Filepath (in output Zip) when ZippingDemonstrates how to set the path for the file entry within the .zip to something different than the path in the filesystem.
// This requires the Chilkat Zip API to have been previously unlocked. // See Unlock Chilkat Zip for sample code. Chilkat.Zip zip = new Chilkat.Zip(); bool success = zip.NewZip("qa_output/zipA.zip"); // When an absolute filepath is passed to AppendOneFileOrDir, the path within the .zip // will be one of two values: (1) just the filename part if saveExtraPath is false, // or (2) the full absolute path, but made relative, if saveExtraPath is true. // (For example, "c:/ck2000/appData/UnitTest/qa_data/hamlet.xml" made relative is // "ck2000/appData/UnitTest/qa_data/hamlet.xml") bool saveExtraPath = false; success = zip.AppendOneFileOrDir("c:/ck2000/appData/UnitTest/qa_data/hamlet.xml",saveExtraPath); if (success != true) { Debug.WriteLine(zip.LastErrorText); return; } // When a relative path is passed to AppendOneFileOrDir, then saveExtraPath does not apply. // For example, assume our current working directory is "c:/ck2000/appData/UnitTest". The following // call to AppendOneFileOrDir creates an entry with the filepath "qa_data/hamlet.xml". success = zip.AppendOneFileOrDir("qa_data/hamlet.xml",saveExtraPath); if (success != true) { Debug.WriteLine(zip.LastErrorText); return; } // Examine the entries int numEntries = zip.NumEntries; int i = 0; while (i < numEntries) { Chilkat.ZipEntry e = zip.GetEntryByIndex(i); Debug.WriteLine(Convert.ToString(i) + ": " + e.FileName); i = i + 1; } // The output so far is: // 0: hamlet.xml // 1: qa_data/hamlet.xml // If we write the .zip as-is, then the zip will have two entries // with the filepaths as shown above. // This writes "qa_output/zipA.zip" success = zip.WriteZip(); // Now change the entry filepaths to whatever is desired. Chilkat.ZipEntry entry = zip.GetEntryByName("hamlet.xml"); if (zip.LastMethodSuccess == false) { Debug.WriteLine("entry not found"); return; } entry.FileName = "Shakespeare/Claudius1.xml"; entry = zip.GetEntryByName("qa_data/hamlet.xml"); if (zip.LastMethodSuccess == false) { Debug.WriteLine("entry not found"); return; } entry.FileName = "Shakespeare/Claudius2.xml"; // Change the name of the .zip to be written and write again: zip.FileName = "qa_output/zipB.zip"; success = zip.WriteZipAndClose(); if (success != true) { Debug.WriteLine(zip.LastErrorText); } else { Debug.WriteLine("Zip created!"); } // Examine both zipA.zip and zipB.zip using 7zip (or another tool) to see the differences. |
