C# and VB.NET Zip Examples - Easily create an archive:

static void Main()
{
    AddFiles("c:\\test.zip", "c:\\temp\\*.cs", "test");
    MoveFiles("c:\\test.zip", "c:\\temp\\*.txt", "test");
}

private static void AddFiles(string fileName,
    string path, string password)
{
    NetXtremeZip zip1 = new NetXtremeZip();
    zip1.FileName = fileName;
    // Create a new zip file.
    zip1.Open(System.IO.FileMode.Create);
    zip1.EncryptionAlgorithm = EncryptionAlgorithm.Aes128;
    zip1.Password = password;
    zip1.AddFiles(path);
    // Close the zip file.
    zip1.Close();
}

private static void MoveFiles(string fileName,
    string path, string password)
{
    NetXtremeZip zip1 = new NetXtremeZip();
    zip1.FileName = fileName;
    // Create a new zip file.
    zip1.Open(System.IO.FileMode.Open);
    zip1.Password = password;
    zip1.MoveFiles(path);
    // Close the zip file.
    zip1.Close();
}

Sub Main()
    AddFiles("c:\test.zip", "c:\temp\*.cs", "test")
    MoveFiles("c:\test.zip", "c:\temp\*.txt", "test")
End Sub

Private Sub AddFiles(ByVal fileName As String, _
    ByVal path As String, ByVal password As String)
    Dim zip1 As New NetXtremeZip()
    zip1.FileName = fileName
    ' Create a new zip file.
    zip1.Open(System.IO.FileMode.Create)
    zip1.EncryptionAlgorithm = EncryptionAlgorithm.Aes128
    zip1.Password = password
    zip1.AddFiles(path)
    ' Close the zip file.
    zip1.Close()
End Sub

Private Sub MoveFiles(ByVal fileName As String, _
    ByVal path As String, ByVal password As String)
    Dim zip1 As New NetXtremeZip()
    zip1.FileName = fileName
    ' Create a new zip file.
    zip1.Open(System.IO.FileMode.Open)
    zip1.Password = password
    zip1.MoveFiles(path)
    ' Close the zip file.
    zip1.Close()
End Sub
