IList<T> Interface

Definition

Represents a collection of objects that can be individually accessed by index.

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

Type Parameters

T

The type of elements in the list.

Derived
Implements

Remarks

The IList<T> generic interface is a descendant of the ICollection<T> generic interface and is the base interface of all generic lists.

Properties

Count

Gets the number of elements contained in the ICollection<T>.

(Inherited from ICollection<T>)
IsReadOnly

Gets a value indicating whether the ICollection<T> is read-only.

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

Gets or sets the element at the specified index.

Methods

Add(T)

Adds an item to the ICollection<T>.

(Inherited from ICollection<T>)
Clear()

Removes all items from the ICollection<T>.

(Inherited from ICollection<T>)
Contains(T)

Determines whether the ICollection<T> contains a specific value.

(Inherited from ICollection<T>)
CopyTo(T[], Int32)

Copies the elements of the ICollection<T> to an Array, starting at a particular Array index.

(Inherited from ICollection<T>)
GetEnumerator()

Returns an enumerator that iterates through a collection.

(Inherited from IEnumerable)
IndexOf(T)

Determines the index of a specific item in the IList<T>.

Insert(Int32, T)

Inserts an item to the IList<T> at the specified index.

Remove(T)

Removes the first occurrence of a specific object from the ICollection<T>.

(Inherited from ICollection<T>)
RemoveAt(Int32)

Removes the IList<T> item at the specified index.

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.
