[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.Core
Assembly: System.Activities.Core (in System.Activities.Core.dll)

Syntax

'Declaration
<ContentPropertyAttribute("Body")> _
Public NotInheritable Class ParallelForEach _
    Inherits NativeActivity
'Usage
Dim instance As ParallelForEach

[ContentPropertyAttribute("Body")]
public sealed class ParallelForEach : NativeActivity

[ContentPropertyAttribute(L"Body")]
public ref class ParallelForEach sealed : public NativeActivity

public final class ParallelForEach extends NativeActivity

[<SealedAttribute>]
[<ContentPropertyAttribute("Body")>]
type ParallelForEach =  
    class
        inherit NativeActivity
    end

Remarks

The embedded statements are scheduled together and run asynchronously, but they do not run on separate threads. Unlike ParallelForEach<T>, this element supports IEnumerable, and can iterate through non-generic lists.
