This code creates four Task objects that execute the Fibonacci method (which returns
a long result). The Fibonacci method receives as an argument the values Numbers[0],
Numbers[1], Numbers[2], and Numbers[4]. (You could even make the Numbers array local to
the event handler that creates the Tasks. Its only purpose in this program is to pass the values
into the StartNew method.)
Because the StartNew method passes the delegate an object as an argument, the
Fibonacci method must be revised to take an object as a parameter. The following
code shows the new method.
private long Fibonacci(object data)
{
long N = (long)data;
}
if (N
