ISet<T> Interface

Definition

Provides the base interface for the abstraction of sets.

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

Type Parameters

T

The type of elements in the set.

Derived
Implements

Remarks

This interface provides methods for implementing sets, which are collections that have unique elements and specific operations. The HashSet<T> and SortedSet<T> collections implement this interface.

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>)

Methods

Add(T)

Adds an element to the current set and returns a value to indicate if the element was successfully added.

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>)
ExceptWith(IEnumerable<T>)

Removes all elements in the specified collection from the current set.

GetEnumerator()

Returns an enumerator that iterates through a collection.

(Inherited from IEnumerable)
IntersectWith(IEnumerable<T>)

Modifies the current set so that it contains only elements that are also in a specified collection.

IsProperSubsetOf(IEnumerable<T>)

Determines whether the current set is a proper (strict) subset of a specified collection.

IsProperSupersetOf(IEnumerable<T>)

Determines whether the current set is a proper (strict) superset of a specified collection.

IsSubsetOf(IEnumerable<T>)

Determines whether a set is a subset of a specified collection.

IsSupersetOf(IEnumerable<T>)

Determines whether the current set is a superset of a specified collection.

Overlaps(IEnumerable<T>)

Determines whether the current set overlaps with the specified collection.

Remove(T)

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

(Inherited from ICollection<T>)
SetEquals(IEnumerable<T>)

Determines whether the current set and the specified collection contain the same elements.

SymmetricExceptWith(IEnumerable<T>)

Modifies the current set so that it contains only elements that are present either in the current set or in the specified collection, but not both.

UnionWith(IEnumerable<T>)

Modifies the current set so that it contains all elements that are present in the current set, in the specified collection, or in both.

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.
