ParallelEnumerable.AsOrdered Method (ParallelQuery)
Enables treatment of a data source as if it were ordered, overriding the default of unordered. AsOrdered may only be invoked on non-generic sequences returned by AsParallel, ParallelEnumerable.Range, and ParallelEnumerable.Repeat.
Assembly: System.Core (in System.Core.dll)
<ExtensionAttribute> Public Shared Function AsOrdered ( source As ParallelQuery ) As ParallelQuery
The input sequence.
Return ValueType: System.Linq.ParallelQuery
The source sequence which will maintain the original ordering in the subsequent query operators.
A natural tension exists between performance and preserving order in parallel processing. By default, a parallelized query behaves as if the ordering of the results is arbitrary unless AsOrdered is applied or there is an explicit OrderBy operator in the query. For more information, see Order Preservation in PLINQ.
