Remarks

Enumerating the collection in C# or Microsoft Visual Basic

A TriggerActionCollection 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<BeginStoryboard> explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable<T> with a BeginStoryboard constraint.

Constructors

TriggerActionCollection() TriggerActionCollection() TriggerActionCollection()

Initializes a new instance of the TriggerActionCollection class.

public : TriggerActionCollection()public TriggerActionCollection()Public Sub New()
Attributes

Properties

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
Parameters
index

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

Value
T T T

The element at the specified index.

Attributes
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 short Size { get; }This member is not implemented in C#This member is not implemented in VB.Net
Value
unsigned short uint uint

The count of items in the collection.

Attributes

Remarks

Note

The equivalent Microsoft .NET API is Count.

Parameters
index
unsigned int UInt32 UInt32

The integer index for the value to retrieve.

Returns

The TriggerAction value at the specified index.

Attributes

Remarks

Note

The equivalent Microsoft .NET API is Item (the indexer).

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)
Returns

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

Attributes

GetMany(UInt32, TriggerAction[]) GetMany(UInt32, TriggerAction[]) GetMany(UInt32, TriggerAction[])

public : unsigned short GetMany(unsigned int startIndex, TriggerAction[] 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
TriggerAction[] TriggerAction[] TriggerAction[]

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 short uint uint

The number of items retrieved.

Attributes

Remarks

Note

The equivalent Microsoft .NET API is CopyTo.

GetView() GetView() GetView()

Gets an immutable view into the collection.

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

An object representing the immutable collection view.
