Create Zip in a BinData Object

See more Zip Examples

Recursively appends files in a directory tree and writes a zip archive into a Chilkat BinData object. C#

bool success = false;

//  This example assumes the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

Chilkat.Zip zip = new Chilkat.Zip();

//  Initialize the zip object.  Because we will never actually write a zip file to the filesystem,
//  the filepath passed to NewZip does not matter.
success = zip.NewZip("x.zip");
if (success != true) {
    Debug.WriteLine(zip.LastErrorText);
    return;
}

//  Append a directory tree.  The call to AppendFiles does
//  not read the file contents or append them to the zip
//  object in memory.  It simply appends references
//  to the files so that when WriteBd, WriteZip, or WriteZipAndClose 
//  is called, the referenced files are streamed and compressed
//  into the .zip output file (or BinData object).

bool recurse = true;
success = zip.AppendFiles("c:/temp/a/*",recurse);
if (success != true) {
    Debug.WriteLine(zip.LastErrorText);
    return;
}

//  Write the zip archive into the bdZip object.
Chilkat.BinData bdZip = new Chilkat.BinData();
success = zip.WriteBd(bdZip);
if (success != true) {
    Debug.WriteLine(zip.LastErrorText);
    return;
}

//  We could directly access the bytes of the zip archive, or perhaps
//  get the zip bytes in base64 format.
string zipAsBase64 = bdZip.GetEncoded("base64");
Debug.WriteLine(zipAsBase64);

//  Or the zip can be used by some other Chilkat method call that accepts
//  a BinData object as an argument.
