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

Returns a sequence with a range of elements in the source sequence moved to a new offset.

Declaration

public static IEnumerable<T> Move<T>(this IEnumerable<T> source, int fromIndex, int count, int toIndex)

Parameters

Type	Name	Description
IEnumerable<T>	source	The source sequence.
int	fromIndex	The zero-based index identifying the first element in the range of elements to move.
int	count	The count of items to move.
int	toIndex	The index where the specified range will be moved.

Returns

Type	Description

Examples

The following code example demonstrates how to move a subsequence from one location to another using Move.

var sequence = Enumerable.Range(0, 6);

// move a subsequence within the larger sequence
var result = sequence
    .Move(3, 2, 0);

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

// This code produces the following output:
// [3, 4, 0, 1, 2, 5]

Exceptions

ArgumentOutOfRangeException	fromIndex, count, or toIndex is less than 0.
