IReadOnlyList<T> Interface

Definition

Namespace:: System.Collections.Generic

Assemblies:: System.Runtime.dll, mscorlib.dll, netstandard.dll

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: Microsoft.Extensions.Primitives.StringValues

System.ArraySegment<T>

System.Collections.Immutable.IImmutableList<T>

Implements: IEnumerable<T> IReadOnlyCollection<T> IEnumerable

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.
