[ExtensionAttribute]
generic<typename T>
static IEnumerable<KeyValuePair<T, int>>^ RunLengthEncode(
	IEnumerable<T>^ sequence
)

[<ExtensionAttribute>]
static member RunLengthEncode : 
        sequence : IEnumerable<'T> -> IEnumerable<KeyValuePair<'T, int>>

Parameters

sequence: Type: System.Collections.GenericIEnumerableT
The sequence to run length encode

Type Parameters

T: The type of the elements in the sequence

Return Value

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