Returns true if all the items match the predicate, otherwise false

Returns true if any of the items match the predicate, otherwise false

Example

if (myEnumerable.any()) {
    // do something because the enumerable has elements
}
Copy

let myEnumerable = new ArrayEnumerable([1, 2, 3, 4]);
if (myEnumerable.any((i) => i == 2)) {
    // the enumerable contains a '2'
}
Copy

Adds a value to the end of the sequence.

Returns the average of the numbers selected by the selector

Concatenates two sequences.

Determines whether a sequence contains a specified element.

Returns the number of items in the enumerable

Returns the unique items designated by the selector

Returns the first item in the enumerable

Returns the first item in the enumerable that matches the predicate

Returns the first item in the enumerable or null

Returns the first item in the enumerable that matches the predicate or null

Iterates over the enumerable and performs the callback on each item. Return false to break.

returns an Enumerator for the items

Groups the items by the key selector using the default comparer

Groups the items by the key selector using the specified comparer

Returns the item at the specified index

Returns the last item in the enumerable

Returns the last item in the enumerable that matches the predicate

Returns the last item in the enumerable or null

Returns the last item in the enumerable that matches the predicate or null

Returns the largest number designated by the selector

Returns the smallest number designated by the selector

Returns an enumerable of items that match the type

Orders the enumerable by the the selector and optional comparer ascending

Orders the enumerable by the the selector and optional comparer descending

Adds a value to the beginning of the sequence.

Selects the items by the selector

Returns a single element only if there is one element in the enumerable

Throws

InvalidOperationException if there is not exactly one item in the enumerable

Returns a single element only if there is one element in the enumerable that matches the predicate

Throws

InvalidOperationException if there is not exactly one item in the enumerable that matches the predicate

Returns a single element only if there is one element in the enumerable. If there are no items in the enumerable, then null is returned

Throws

InvalidOperationException if there is not exactly one or zero items in the enumerable

Returns a single element only if there is one element in the enumerable that matches the predicate. If there are no items in the enumerable, then null is returned

Throws

InvalidOperationException if there is not exactly one or zero item in the enumerable that matches the predicate

Skips the number of items specified. If the count is larger than the size of the enumerable, no items will be returned.

Splits a enumerable into two queryables. One set is for true predicates, the other set is for false predicates.

Sums the items in the enumerable using the selector

Takes the number of specified items from the enumerable. If the count is larger than the size of the enumerable, all items will be returned

Returns the items as an array

Returns a dictionary based on the key and value selctors

Returns the items as a List

Filters the enumerable by the predicate
