Append Method

In namespace: System.Linq

Appends an element to the end of a sequence.

Syntax


                public static IEnumerable<TSource> Append<TSource>(this IEnumerable<TSource> source, TSource element)

Parameters

Name	Description
`source`	An `IEnumerable<TSource>` to append the element to.
`element`	The element to append to the sequence.

Type Parameters

TSource

The type of the elements of source.

Remarks

The Append method returns a new sequence that contains all elements in the input sequence, followed by the specified element.

This method does not modify the original sequence.

If the input sequence implements IList<T>, the Append operation can be more efficient.

Example


                // Sample array
                int[] numbers = { 1, 2, 3, 4 };

                // Append an element
                IEnumerable<int> appendedSequence = numbers.Append(5);

                // Print the new sequence
                foreach (int number in appendedSequence)
                {
                    Console.WriteLine(number);
                }
                // Output:
                // 1
                // 2
                // 3
                // 4
                // 5
