NameValueCollection Constructor (IHashCodeProvider, IComparer)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Note: This API is now obsolete.

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

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

[ObsoleteAttribute("Please use NameValueCollection(IEqualityComparer) instead.")]
public NameValueCollection(
	IHashCodeProvider hashProvider,
	IComparer comparer


Type: System.Collections.IHashCodeProvider

The IHashCodeProvider that will supply the hash codes for all keys in the NameValueCollection.

Type: System.Collections.IComparer

The IComparer to use to determine whether two keys are equal.

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.
