Assembly: DigitalRune (in DigitalRune.dll) Version: 1.20.0.0 (1.20.1.14552)

Syntax

C++

Copy

public static void ForEach<T>(
	IEnumerable<T> collection,
	Action<T> action
)

Public Shared Sub ForEach(Of T) ( 
	collection As IEnumerable(Of T),
	action As Action(Of T)
)

public:
generic<typename T>
static void ForEach(
	IEnumerable<T>^ collection, 
	Action<T>^ action
)

static member ForEach : 
        collection : IEnumerable<'T> * 
        action : Action<'T> -> unit

Parameters

collection: Type: System.Collections.GenericIEnumerableT
The enumerable data source.
action: Type: SystemActionT
The method to execute at each iteration. The item to process is supplied as the parameter.

Type Parameters

T: The type of item to iterate over.

Exceptions

Exception	Condition
ArgumentNullException	Either collection or action is .

Remarks

The parallel foreach-loop has a few disadvantages: Enumerating the sequence in parallel requires locking. In addition, creating an IEnumeratorT object allocates memory on the managed heap. It is therefore recommended to use the parallel for-loop instead of the parallel for-each loop where possible.
