ParallelForEach Class

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Enumerates the elements of a collection and executes an embedded statement for each element of the collection in parallel.

Namespace:  System.Activities.Statements
Assembly:  System.Activities (in System.Activities.dll)
[ContentPropertyAttribute("Body")]
public sealed class ParallelForEach : NativeActivity

The embedded statements are scheduled together and run asynchronously, but they do not run on separate threads so each successive activity will only execute when the previously scheduled activity completes or goes idle. If none of the child activities of this activity go idle, this activity execute in the same way that a ForEach activity does.so each successive activitiy will only execute when the previously scheduled activity completes or goes idle. If none of the child activities of this activity go idle, this activity execute in the same way that a Sequence activity does.. Unlike ParallelForEach<T>, this element supports IEnumerable, and can iterate through non-generic lists.
