CollectionBase Constructors

Definition

Namespace:

System.Collections

Assemblies:

netstandard.dll, System.Collections.NonGeneric.dll

Initializes a new instance of the CollectionBase class.

Overloads

CollectionBase()	Initializes a new instance of the CollectionBase class with the default initial capacity.
CollectionBase(Int32)	Initializes a new instance of the CollectionBase class with the specified capacity.

CollectionBase()

Source:

CollectionBase.cs

Initializes a new instance of the CollectionBase class with the default initial capacity.

C#

protected CollectionBase();

Remarks

The capacity of a CollectionBase is the number of elements that the CollectionBase can hold. As elements are added to a CollectionBase, the capacity is automatically increased as required by reallocating the internal array.

If the size of the collection can be estimated, specifying the initial capacity eliminates the need to perform a number of resizing operations while adding elements to the CollectionBase.

This constructor is an O(1) operation.

CollectionBase(Int32)

Source:

CollectionBase.cs

Initializes a new instance of the CollectionBase class with the specified capacity.

C#

protected CollectionBase(int capacity);

Parameters

capacity

Int32

The number of elements that the new list can initially store.

Remarks

The capacity of a CollectionBase is the number of elements that the CollectionBase can hold. As elements are added to a CollectionBase, the capacity is automatically increased as required by reallocating the internal array.

If the size of the collection can be estimated, specifying the initial capacity eliminates the need to perform a number of resizing operations while adding elements to the CollectionBase.

This constructor is an O(n) operation, where n is capacity.
