Executes a for (For in Visual Basic) loop with 64-bit indexes in which iterations may run in parallel and loop options can be configured.
A structure that contains information about which portion of the loop completed.
Supports 64-bit indexes. The body delegate is invoked once for each value in the iteration range (fromInclusive, toExclusive). It is provided with the iteration count (long) as a parameter.
If fromInclusive is greater than or equal to toExclusive, then the method returns immediately without performing any iterations.
