Remarks

Collection member lists

For JavaScript, PnpObjectCollection has the members shown in the member lists. In addition, PnpObjectCollection supports a length property, members of Array.prototype, and using an index to access items.

Enumerating the collection in C# or Microsoft Visual Basic

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

Properties

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

Gets the element at the specified index in the read-only list.

This member is not implemented in C++T this[int index] { get; }ReadOnly Property Item(index As Integer) As T
Parameters
index
System.Int32 System.Int32 System.Int32

The zero-based index of the element to get.

Value
T T T

The element at the specified index in the read-only list.

Attributes

Size Size Size

Returns the number of items in the collection.

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

The number of items in the collection.

Attributes

Methods

First() First() First()

Returns the iterator for iteration over the items in the collection.

public IIterator<PnpObject> First()This member is not implemented in C#This member is not implemented in VB.Net
Returns

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

Attributes

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

Returns the PnpObject located at the specified index.

public PnpObject GetAt(UInt32 index)This member is not implemented in C#This member is not implemented in VB.Net
Parameters
index
System.UInt32 System.UInt32 System.UInt32

The integer index for the value to retrieve.

Returns

The PnpObject at the specified index.

Attributes

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
System.Collections.Generic.IEnumerator<T> System.Collections.Generic.IEnumerator<T> System.Collections.Generic.IEnumerator<T>

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

GetMany(UInt32, PnpObject[]) GetMany(UInt32, PnpObject[]) GetMany(UInt32, PnpObject[])

Retrieves multiple elements in a single pass through the iterator.

public unsigned short GetMany(UInt32 startIndex, PnpObject[] items)This member is not implemented in C#This member is not implemented in VB.Net
Parameters
startIndex
System.UInt32 System.UInt32 System.UInt32

The index from which to start retrieval.

items
Windows.Devices.Enumeration.Pnp.PnpObject[] Windows.Devices.Enumeration.Pnp.PnpObject[] Windows.Devices.Enumeration.Pnp.PnpObject[]

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
uint uint uint

The number of items retrieved.

Attributes

IndexOf(PnpObject, UInt32) IndexOf(PnpObject, UInt32) IndexOf(PnpObject, UInt32)

Retrieves the index of the specified item.

public PlatForm::Boolean IndexOf(PnpObject value, UInt32 index)This member is not implemented in C#This member is not implemented in VB.Net
Parameters
value
PnpObject PnpObject PnpObject

The value to find in the collection.

index
System.UInt32 System.UInt32 System.UInt32

The index of the item to find, if found.

Returns
bool bool bool

True if an item with the specified value was found; otherwise, False.
