Method Slice

Slice<T>(IEnumerable<T>, int, int)

Extracts a contiguous count of elements from a sequence at a particular zero-based starting index

Declaration

public static IEnumerable<T> Slice<T>(this IEnumerable<T> source, int startIndex, int count)

Parameters

Type	Name	Description
IEnumerable<T>	source	The sequence from which to extract elements
int	startIndex	The zero-based index at which to begin slicing
int	count	The number of items to slice out of the index

Returns

Type	Description
IEnumerable<T>	A new sequence containing any elements sliced out from the source sequence

Type Parameters

Name	Description
T	The type of the elements in the source sequence

Remarks

If the starting position or count specified result in slice extending past the end of the sequence, it will return all elements up to that point. There is no guarantee that the resulting sequence will contain the number of elements requested - it may have anywhere from 0 to count.

Examples

The following code example demonstrates how to take a range of elements from a sequence using Slice.

var sequence = Enumerable.Range(1, 10);

// Take a slice of the sequence
var result = sequence.Slice(2, 3);

Console.WriteLine(
    "[" +
    string.Join(", ", result) +
    "]");

// This code produces the following output:
// [3, 4, 5]
