Create a Zip Entirely in Memory

See more Zip Examples

Demonstrates how to create a .zip from in-memory byte data and strings, and to write the .zip to an in-memory image. .NET Core C#

bool success = false;

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

Chilkat.Crypt2 crypt = new Chilkat.Crypt2();
Chilkat.Zip zip = new Chilkat.Zip();

success = zip.NewZip("test.zip");
if (success == false) {
    Debug.WriteLine(zip.LastErrorText);
    return;
}

// Add the bytes 0x00 0x01 0x02 0x03 ... 0x0F as a file in the .zip
Chilkat.BinData bd = new Chilkat.BinData();
bd.AppendEncoded("000102030405060708090A0B0C0D0E0F","hex");
zip.AddBd("binaryData.dat",bd);

// Add the string "Hello World!" to the .zip
zip.AddString("helloWorld.txt","Hello World!","utf-8");

byte[] zipFileInMemory = null;
zipFileInMemory = zip.WriteToMemory();

// We could save these files to a file, and it is a valid .zip
Chilkat.FileAccess fac = new Chilkat.FileAccess();
success = fac.WriteEntireFile("test.zip",zipFileInMemory);
if (success == false) {
    Debug.WriteLine(fac.LastErrorText);
    return;
}

Debug.WriteLine("Zip Created!");
