NameValueCollection(NameValueCollection) NameValueCollection(NameValueCollection) NameValueCollection(NameValueCollection) NameValueCollection(NameValueCollection)

Copies the entries from the specified NameValueCollection to a new NameValueCollection with the same initial capacity as the number of entries copied and using the same hash code provider and the same comparer as the source collection.

NameValueCollection(Int32) NameValueCollection(Int32) NameValueCollection(Int32) NameValueCollection(Int32)

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.

NameValueCollection(Int32, IEqualityComparer) NameValueCollection(Int32, IEqualityComparer) NameValueCollection(Int32, IEqualityComparer) NameValueCollection(Int32, IEqualityComparer)

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

NameValueCollection(Int32, NameValueCollection) NameValueCollection(Int32, NameValueCollection) NameValueCollection(Int32, NameValueCollection) NameValueCollection(Int32, NameValueCollection)

Copies the entries from the specified NameValueCollection to a new NameValueCollection with the specified initial capacity or the same initial capacity as the number of entries copied, whichever is greater, and using the default case-insensitive hash code provider and the default case-insensitive comparer.

NameValueCollection() NameValueCollection() NameValueCollection()

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.

public:
 NameValueCollection();
public NameValueCollection ();
Public Sub New ()

Remarks

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.

Public Sub New (equalityComparer As IEqualityComparer)

Parameters

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

This constructor is an O(1) operation.
