Remarks

A HubSectionCollection is the type of object that you get from the Sections property of a Hub. All the properties that use a HubSectionCollection in the Windows Runtime API are read-only properties, where the property is initialized with zero items when an object is first instantiated. But you can then add, remove or query items in the collection at run time, using the HubSectionCollection properties and methods.

Enumerating the collection in C# or Microsoft Visual Basic

A HubSectionCollection is enumerable, so you can use language-specific syntax such as foreach in C# to enumerate the items in the collection. The compiler does the type-casting for you and you won't need to cast to IEnumerable explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable with a HubSection constraint.

Properties

Item[Int32] Item[Int32] Item[Int32] Item[Int32]

Gets or sets the element at the specified index.

This member is not implemented in C++
T this[int index] { get; set; }
Property Item(index As Integer) As T
T this[int index] { get; set; }
Parameters
index

The zero-based index of the element to get or set.

Value
T T T

The element at the specified index.

Exceptions

index is not a valid index in the System.Collections.Generic.IList`1.

The property is set and the System.Collections.Generic.IList`1 is read-only.

Size Size Size

Gets the size (count) of the collection.

public : unsigned int Size { get; }
This member is not implemented in C#
This member is not implemented in VB.Net
Value
unsigned int uint uint

The count of items in the collection.

Remarks

If you are programming using C# or Microsoft Visual Basic, use the Count property.

Methods

Append(HubSection) Append(HubSection) Append(HubSection)

Adds a new item to the collection.

public : void Append(HubSection value)
This member is not implemented in C#

Parameters
value
HubSection HubSection HubSection

The new item to add.

Remarks

To add an item to a position in the collection that's not at the collection end, use InsertAt.

If you are programming using C# or Microsoft Visual Basic, the equivalent method is Add.

Clear() Clear() Clear()

The iterator object. The iterator's current position is at the 0-index position, or at the collection end if the collection is empty.

GetAt(UInt32) GetAt(UInt32) GetAt(UInt32)

Returns the item located at the specified index.

public : HubSection GetAt(unsigned int index)
This member is not implemented in C#
This member is not implemented in VB.Net
Parameters

unsigned int UInt32 UInt32

The integer index for the value to retrieve.

Returns

The item value at the specified index.

GetEnumerator() GetEnumerator() GetEnumerator() GetEnumerator()

Returns an enumerator that iterates through the collection.

This member is not implemented in C++
IEnumerator<T> GetEnumerator()
Function GetEnumerator As IEnumerator(Of T)
IEnumerator<T> GetEnumerator()
Returns

An enumerator that can be used to iterate through the collection.

GetMany(UInt32, HubSection[]) GetMany(UInt32, HubSection[]) GetMany(UInt32, HubSection[])

Retrieves multiple elements in a single pass through the iterator.

public : unsigned int GetMany(unsigned int startIndex, HubSection[] items)
This member is not implemented in C#
This member is not implemented in VB.Net
Parameters
startIndex
unsigned int UInt32 UInt32

The index from which to start retrieval.

items
HubSection[] HubSection[] HubSection[]

Provides the destination for the result. Size the initial array size as a "capacity" in order to specify how many results should be retrieved.

Returns
unsigned int uint uint

The number of items retrieved.

GetView() GetView() GetView()

Gets an immutable view into the collection.

public : IVectorView<HubSection> GetView()
This member is not implemented in C#
This member is not implemented in VB.Net
Returns
IVectorView<HubSection> IReadOnlyList<HubSection> IReadOnlyList<HubSection>

An object representing the immutable collection view.

IndexOf(T) IndexOf(T) IndexOf(T) IndexOf(T)

Determines the index of a specific item in the System.Collections.Generic.IList`1.

This member is not implemented in C++
int IndexOf(T item)
Function IndexOf(item As T) As Integer
int IndexOf(T item)
Parameters
item
T T T

The object to locate in the System.Collections.Generic.IList`1.

Returns

The index of item if found in the list; otherwise, -1.

IndexOf(HubSection, UInt32) IndexOf(HubSection, UInt32) IndexOf(HubSection, UInt32)

Retrieves the index of the specified item.

public : Platform::Boolean IndexOf(HubSection value, unsigned int index)
This member is not implemented in C#
This member is not implemented in VB.Net
Parameters
value
HubSection HubSection HubSection

The value to find in the collection.

index
unsigned int UInt32 UInt32

The index of the item, if it is found.

Returns
Platform::Boolean bool bool

true if an item with the specified value was found; otherwise, false.

Insert(Int32, T) Insert(Int32, T) Insert(Int32, T) Insert(Int32, T)

Inserts an item to the System.Collections.Generic.IList`1 at the specified index.

This member is not implemented in C++
void Insert(int index, T item)
Sub Insert(index As Integer, item As T)
void Insert(int index, T item)
Parameters
index

The zero-based index at which item should be inserted.

item
T T T

The object to insert into the System.Collections.Generic.IList`1.

Exceptions

index is not a valid index in the System.Collections.Generic.IList`1.

The System.Collections.Generic.IList`1 is read-only.

InsertAt(UInt32, HubSection) InsertAt(UInt32, HubSection) InsertAt(UInt32, HubSection)

Inserts the specified item at the specified index.

public : void InsertAt(unsigned int index, HubSection value)

This member is not implemented in VB.Net
Parameters
index

Remarks

InsertAt expands the collection and moves all subsequent index items by one.

Parameters
index
unsigned int UInt32 UInt32

The index position of the item to remove.

Remarks

If successful, calling this method reduces the collection size by one. Items with index values greater than the called index have their index values reduced by one.

RemoveAtEnd() RemoveAtEnd() RemoveAtEnd()
