IReadOnlyList<T> Interface

Definition

Represents a read-only collection of elements that can be accessed by index.

generic <typename T>
public interface class IReadOnlyList : System::Collections::Generic::IEnumerable<T>, System::Collections::Generic::IReadOnlyCollection<T>
public interface IReadOnlyList<out T> : System.Collections.Generic.IEnumerable<out T>, System.Collections.Generic.IReadOnlyCollection<out T>
type IReadOnlyList<'T> = interface
    interface IReadOnlyCollection<'T>
    interface seq<'T>
    interface IEnumerable
Public Interface IReadOnlyList(Of Out T)
Implements IEnumerable(Of Out T), IReadOnlyCollection(Of Out T)

Type Parameters

T

The type of elements in the read-only list.

Derived
Implements

Remarks

The IReadOnlyList<T> represents a list in which the number and order of list elements is read-only. The content of list elements is not guaranteed to be read-only.

Properties

Count

Gets the number of elements in the collection.

(Inherited from IReadOnlyCollection<T>)
Item[Int32]

Gets the element at the specified index in the read-only list.

Methods

GetEnumerator()

Returns an enumerator that iterates through a collection.

(Inherited from IEnumerable)

Extension Methods

CopyToDataTable<T>(IEnumerable<T>)

Returns a DataTable that contains copies of the DataRow objects, given an input IEnumerable<T> object where the generic parameter T is DataRow.

CopyToDataTable<T>(IEnumerable<T>, DataTable, LoadOption)

Copies DataRow objects to the specified DataTable, given an input IEnumerable<T> object where the generic parameter T is DataRow.

CopyToDataTable<T>(IEnumerable<T>, DataTable, LoadOption, FillErrorEventHandler)

Copies DataRow objects to the specified DataTable, given an input IEnumerable<T> object where the generic parameter T is DataRow.

Cast<TResult>(IEnumerable)

Casts the elements of an IEnumerable to the specified type.

OfType<TResult>(IEnumerable)

Filters the elements of an IEnumerable based on a specified type.

AsParallel(IEnumerable)

Enables parallelization of a query.

AsQueryable(IEnumerable)

Converts an IEnumerable to an IQueryable.

Ancestors<T>(IEnumerable<T>)

Returns a collection of elements that contains the ancestors of every node in the source collection.

Ancestors<T>(IEnumerable<T>, XName)

Returns a filtered collection of elements that contains the ancestors of every node in the source collection. Only elements that have a matching XName are included in the collection.

DescendantNodes<T>(IEnumerable<T>)

Returns a collection of the descendant nodes of every document and element in the source collection.

Descendants<T>(IEnumerable<T>)

Returns a collection of elements that contains the descendant elements of every element and document in the source collection.

Descendants<T>(IEnumerable<T>, XName)

Returns a filtered collection of elements that contains the descendant elements of every element and document in the source collection. Only elements that have a matching XName are included in the collection.

Elements<T>(IEnumerable<T>)

Returns a collection of the child elements of every element and document in the source collection.

Elements<T>(IEnumerable<T>, XName)

Returns a filtered collection of the child elements of every element and document in the source collection. Only elements that have a matching XName are included in the collection.

InDocumentOrder<T>(IEnumerable<T>)

Returns a collection of nodes that contains all nodes in the source collection, sorted in document order.

Nodes<T>(IEnumerable<T>)

Returns a collection of the child nodes of every document and element in the source collection.

Remove<T>(IEnumerable<T>)

Removes every node in the source collection from its parent node.
