Remarks

Enumerating the collection in C# or Microsoft Visual Basic

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

Constructors

PointCollection()

Initializes a new instance of the PointCollection class.

Properties

Size

Gets the size (count) of the collection.

Methods

Append(Point)

Adds a new item to the collection.
Clear()

Removes all items from the collection.
First()

Returns an iterator for the items in the collection.
GetAt(UInt32)

Returns the item located at the specified index.
GetMany(UInt32, Point[])

Retrieves multiple elements in a single pass through the iterator.
GetView()

Gets an immutable view into the collection.
IndexOf(Point, UInt32)

Retrieves the index of the specified item.
InsertAt(UInt32, Point)

Inserts the specified item at the specified index.
RemoveAt(UInt32)

Removes the item at the specified index.
RemoveAtEnd()

Removes the last item in the collection.
ReplaceAll(Point[])

Initially clears the collection, then inserts the provided array as new items.
SetAt(UInt32, Point)

Sets the value at the specified index to the Point value specified.
