Remarks

The ArrangedElementCollection class represents a collection of objects arranged on a design surface or inside a parent System.Windows.Forms.ContainerControl.

There are no publicly defined constructors in ArrangedElementCollection because it is designed to be used only internally within the .NET Framework. However, classes derived from ArrangedElementCollection, such as System.Windows.Forms.Control.ControlCollection, are available to the developer.

Properties

Count	Gets the number of elements in the collection.
IsReadOnly	Gets a value indicating whether the collection is read-only.

Methods

CopyTo(Array, Int32)	Copies the entire contents of this collection to a compatible one-dimensional Array, starting at the specified index of the target array.
Equals(Object)	Determines whether two ArrangedElementCollection instances are equal.
GetEnumerator()	Returns an enumerator for the entire collection.
GetHashCode()	Returns the hash code for this instance.
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)

Thread Safety

Public static (Shared in Visual Basic) members of this type are thread safe. Instance members are not guaranteed to be thread safe.

An ArrangedElementCollection can support multiple readers concurrently, as long as the collection is not modified. The GetEnumerator() method returns an IEnumerator that can be used to access elements.

Enumerating through a collection is intrinsically not a thread-safe procedure. Even when a collection is synchronized, other threads could still modify the collection, which causes the enumerator to throw an exception. To guarantee thread safety during enumeration, you can either lock the collection during the entire enumeration or catch the exceptions resulting from changes made by other threads.
