NameObjectCollectionBase()

Source:

NameObjectCollectionBase.cs

Initializes a new instance of the NameObjectCollectionBase class that is empty.

protected:
 NameObjectCollectionBase();

protected NameObjectCollectionBase ();

Protected Sub New ()

Remarks

The capacity of a NameObjectCollectionBase is the number of elements that the NameObjectCollectionBase can hold. As elements are added to a NameObjectCollectionBase, 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 NameObjectCollectionBase.

The hash code provider dispenses hash codes for keys in the NameObjectCollectionBase instance. The default hash code provider is the CaseInsensitiveHashCodeProvider.

The comparer determines whether two keys are equal. The default comparer is the CaseInsensitiveComparer.

This constructor is an O(1) operation.

NameObjectCollectionBase(IEqualityComparer)

Source:

NameObjectCollectionBase.cs

Initializes a new instance of the NameObjectCollectionBase class that is empty, has the default initial capacity, and uses the specified IEqualityComparer object.

protected:
 NameObjectCollectionBase(System::Collections::IEqualityComparer ^ equalityComparer);

protected NameObjectCollectionBase (System.Collections.IEqualityComparer? equalityComparer);

new System.Collections.Specialized.NameObjectCollectionBase : System.Collections.IEqualityComparer -> System.Collections.Specialized.NameObjectCollectionBase

Protected Sub New (equalityComparer As IEqualityComparer)

Parameters

equalityComparer

IEqualityComparer

The IEqualityComparer object to use to determine whether two keys are equal and to generate hash codes for the keys in the collection.

Remarks

The capacity of a NameObjectCollectionBase object is the number of elements that the NameObjectCollectionBase can hold. As elements are added to a NameObjectCollectionBase, 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 NameObjectCollectionBase.

The IEqualityComparer object combines the comparer and the hash code provider. The hash code provider dispenses hash codes for keys in the NameObjectCollectionBase. The comparer determines whether two keys are equal.

This constructor is an O(1) operation.

NameObjectCollectionBase(Int32)

Source:

NameObjectCollectionBase.cs

Initializes a new instance of the NameObjectCollectionBase class that is empty, has the specified initial capacity, and uses the default hash code provider and the default comparer.

protected:
 NameObjectCollectionBase(int capacity);

protected NameObjectCollectionBase (int capacity);

new System.Collections.Specialized.NameObjectCollectionBase : int -> System.Collections.Specialized.NameObjectCollectionBase

Protected Sub New (capacity As Integer)

Parameters

capacity

Int32

The approximate number of entries that the NameObjectCollectionBase instance can initially contain.

Exceptions

ArgumentOutOfRangeException

capacity is less than zero.

Remarks

The capacity of a NameObjectCollectionBase is the number of elements that the NameObjectCollectionBase can hold. As elements are added to a NameObjectCollectionBase, 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 NameObjectCollectionBase.

The hash code provider dispenses hash codes for keys in the NameObjectCollectionBase instance. The default hash code provider is the CaseInsensitiveHashCodeProvider.

The comparer determines whether two keys are equal. The default comparer is the CaseInsensitiveComparer.

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