Returns the iterator for iteration over the items in the collection.
public: virtual IIterator<DependencyObject ^> ^ First() = IIterable<DependencyObject ^>::First;
public IIterator<DependencyObject> First();
Public Function First () As IIterator(Of DependencyObject)
The iterator object. The iterator's current position is at the 0-index position, or at the collection end if the collection is empty.
You can iterate through a DependencyObjectCollection in C# or Microsoft Visual Basic. In many cases, such as using foreach syntax, the compiler does this casting for you and you won't need to cast to
IEnumerable<DependencyObject> explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable with a DependencyObject constraint.
