(C# UWP/WinRT) Set Entry Filepath (in output Zip) when Zipping

Demonstrates 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 = await zip.AppendOneFileOrDirAsync("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 = await zip.AppendOneFileOrDirAsync("qa_data/hamlet.xml",saveExtraPath);
if (success != true) {

// Examine the entries
int numEntries = zip.NumEntries;
int i = 0;

    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 = await zip.WriteZipAsync();

// 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/Claudius2.xml";

// Change the name of the .zip to be written and write again:
zip.FileName = "qa_output/zipB.zip";
success = await zip.WriteZipAndCloseAsync();
if (success != true) {

// Examine both zipA.zip and zipB.zip using 7zip (or another tool) to see the differences.
