A Trick Question With Closures

Given the following code, what do you expect the output to be?

for (int i = 0; i < 100; ++i)
{
    ThreadPool.QueueUserWorkItem(delegate
    {
        Console.WriteLine(i);
    });
}

Keep that answer in your head! Now...what do you expect the output of the following?

int i;
for (i = 0; i < 100; ++i)
{
    ThreadPool.QueueUserWorkItem(delegate
    {
        Console.WriteLine(i);
    });
}

Were your answers the same? Different? Why?
