Members

The PnpObjectCollection class has these types of members:

Methods

The PnpObjectCollection class has these methods. With C#, Visual Basic, and C++, it also inherits methods from the Object class.

MethodDescription
First [C++, JavaScript]Returns the iterator for iteration over the items in the collection.
GetAt [C++, JavaScript]Returns the PnpObject located at the specified index.
GetMany [C++, JavaScript]Retrieves multiple elements in a single pass through the iterator.
IndexOf [C++, JavaScript]Retrieves the index of the specified item.

PropertyAccess typeDescription

Count [C#, VB]

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.
