Examples

Cancel Apple Archive extraction after a certain time.

using (System.Threading.CancellationTokenSource cts = new System.Threading.CancellationTokenSource())
{
    cts.CancelAfter(System.TimeSpan.FromSeconds(60)); 
    using (var a = new AppleArchive("big.aar", new AppleArchiveLoadOptions() { CancellationToken = cts.Token }))
    {
        try
        {
             a.ExtractToDirectory("destination");
        }
        catch(System.OperationCanceledException)
        {
            Console.WriteLine("Extraction was cancelled after 60 seconds");
        }
    }
}

Using with Task

System.Threading.CancellationTokenSource cts = new System.Threading.CancellationTokenSource();
cts.CancelAfter(System.TimeSpan.FromSeconds(60));
System.Threading.Tasks.Task t = System.Threading.Tasks.Task.Run(delegate()
{
    var loadOptions = new AppleArchiveLoadOptions() { CancellationToken = cts.Token };
    using (var a = new AppleArchive("big.aar", loadOptions))
    {
         a.ExtractToDirectory("destination");
    }
}, cts.Token);

t.ContinueWith(delegate(System.Threading.Tasks.Task antecedent)
{
     if (antecedent.IsCanceled)
     {
         Console.WriteLine("Extraction was cancelled after 60 seconds");
     }

     cts.Dispose();
});

Cancellation mostly results in some data not being extracted.
