) As IEnumerable(Of Integer())

C++/CLI

public:
static IEnumerable<array<int>^>^ CombinationsWithReplacement(
	int count, 
	int length, 
	array<int>^ result
)

static member CombinationsWithReplacement : 
        count : int * 
        length : int * 
        result : int[] -> IEnumerable<int[]>

Parameters

count Int32: The size of the set to draw combinations from.
length Int32: The length of the combinations.
result Int32[]: An array that is to hold the result.

Return Value

IEnumerable<Int32[]>
A sequence of integer arrays that contain the indexes of all combinations with replacement of length elements from a set of size count.

Remarks

The indexes are returned each time in the same array, result. Its elements should not be modified. If they are modified, the results are unpredictable.

Exceptions

ArgumentOutOfRangeException

length is less than zero.
