The type of elements of source.

Parameters

source
ParallelQuery<TSource>

A ParallelQuery on which to set the option.

executionMode

source is a null reference (Nothing in Visual Basic).

ArgumentException

Remarks

The execution mode specifies whether PLINQ will attempt to fall back to sequential execution if it detects certain query shapes. For more information and examples, see How to: Specify the Execution Mode in PLINQ.
