Determines whether the end of the first sequence is equivalent to the second sequence, using the default equality comparer.

public static bool EndsWith<T>(this IEnumerable<T> source, IEnumerable<T> sequence);

T
The type of the elements of the sequences.

source IEnumerable <TSource>
The source sequence.

sequence IEnumerable <TSource>
The target sequence.

Boolean
true if source ends with sequence, false otherwise.

ArgumentNullException
source is null

-or-

sequence is null

The following code example demonstrates how to use EndsWith(IEnumerable sequence) to check if the a sequence ends with another sequence.

int[] sourceNumbers = new int[] { 1, 2, 3 };

int[] tail1 = new int[] { 2, 3 };
int[] tail2 = new int[] { 1, 2, 3 };
int[] tail3 = new int[] { 0, 1, 2, 3 };

sourceNumbers.EndsWith(tail1);
//=> true

sourceNumbers.EndsWith(tail2);
//=> true

sourceNumbers.EndsWith(tail3);
//=> false

Determines whether the end of the first sequence is equivalent to the second sequence, using the default equality comparer.

public static bool EndsWith<T>(this IEnumerable<T> source, IEnumerable<T> sequence, IEqualityComparer<T>? comparer);

T
The type of the elements of the sequences.

source IEnumerable <TSource>
The source sequence.

sequence IEnumerable <TSource>
The target sequence.

comparerIEqualityComparer
An equality comparer to compare values.

Boolean
true if source ends with sequence, false otherwise.

ArgumentNullException
source is null

The following code example demonstrates how to use EndsWith(IEnumerable sequence, IEqualityComparer? comparer) to check if the a sequence ends with another sequence.

string[] source = new string[] { "a", "b", "C"};

string[] tail1 = new string[] { "b", "c" };
string[] tail2 = new string[] { "A", "b", "C" };
string[] tail3 = new string[] { "a", "b", "C", "d" };

sourceNumbers.EndsWith(tail1, StringComparer.OrdinalIgnoreCase);
//=> true

sourceNumbers.EndsWith(tail2, StringComparer.OrdinalIgnoreCase);
//=> true

sourceNumbers.EndsWith(tail3, StringComparer.OrdinalIgnoreCase);
//=> false
