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 with a PnpObject constraint.

Properties

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

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

Size Size Size Size Size

Returns the number of items in the collection.

Methods

First() First() First() First() First()

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

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

Returns the PnpObject located at the specified index.

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

Returns an enumerator that iterates through the collection.

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

Retrieves multiple elements in a single pass through the iterator.

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

Retrieves the index of the specified item.
