NameObjectCollectionBase Constructor (Int32, IEqualityComparer)

NameObjectCollectionBase Constructor (Int32, IEqualityComparer)

 

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

Namespace:   System.Collections.Specialized
Assembly:  System (in System.dll)

Protected Sub New (
	capacity As Integer,
	equalityComparer As IEqualityComparer
)

Parameters

capacity
Type: System.Int32

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

equalityComparer
Type: System.Collections.IEqualityComparer

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

Exception Condition
ArgumentOutOfRangeException

capacity is less than zero.

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(n) operation, where n is the capacity parameter.
