NameValueCollection.NameValueCollection() Constructor

Initializes a new instance of the NameValueCollection class that is empty, has the default initial capacity and uses the default case-insensitive hash code provider and the default case-insensitive comparer.

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

public NameValueCollection ()
public NameValueCollection ()
public function NameValueCollection ()
Not applicable.

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

The hash code provider dispenses hash codes for keys in the NameValueCollection. 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.
