ArrayExtensions.Enumerate<T>(T[]) Method

Definition

Namespace:

Microsoft.Toolkit.HighPerformance

Assembly:

Microsoft.Toolkit.HighPerformance.dll

Package:

Microsoft.Toolkit.HighPerformance v7.1.2

Enumerates the items in the input T array instance, as pairs of reference/index values. This extension should be used directly within a foreach loop:

int[] numbers = new[] { 1, 2, 3, 4, 5, 6, 7 };

foreach (var item in numbers.Enumerate())
{
    // Access the index and value of each item here...
    int index = item.Index;
    ref int value = ref item.Value;
}

The compiler will take care of properly setting up the foreach loop with the type returned from this method.

public static Microsoft.Toolkit.HighPerformance.Enumerables.SpanEnumerable<T> Enumerate<T> (this T[] array);

static member Enumerate : 'T[] -> Microsoft.Toolkit.HighPerformance.Enumerables.SpanEnumerable<'T>

<Extension()>
Public Function Enumerate(Of T) (array As T()) As SpanEnumerable(Of T)

Type Parameters

T

The type of items to enumerate.

Parameters

array

T[]

The source T array to enumerate.

Returns

SpanEnumerable<T>

A wrapper type that will handle the reference/index enumeration for array.

Remarks

The returned SpanEnumerable<T> value shouldn't be used directly: use this extension in a foreach loop.
