Run-length encodes a sequence by converting consecutive instances of the same element into a KeyValuePair{T,int} representing the item and its occurrence count. This overload uses a custom equality comparer to identify equivalent items.

Namespace:  MoreLinq

public static IEnumerable<KeyValuePair<T, int>> RunLengthEncode<T>(
	this IEnumerable<T> sequence,
	IEqualityComparer<T> comparer


Type: System.Collections.GenericIEnumerableT
The sequence to run length encode
Type: System.Collections.GenericIEqualityComparerT
The comparer used to identify equivalent items

Type Parameters

The type of the elements in the sequence

Return Value

Type: IEnumerableKeyValuePairT, Int32
A sequence of KeyValuePair{T,int} where they key is the element and the value is the occurrence count
