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

public NameValueCollection (
	int capacity,
	IEqualityComparer equalityComparer

	IEqualityComparer equalityComparer
)
public function NameValueCollection (
	capacity : int, 
	equalityComparer : IEqualityComparer
)
Not applicable.

Parameters

capacity

The initial number of entries that the NameValueCollection object can contain.

equalityComparer

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

Exception typeCondition

ArgumentOutOfRangeException

capacity is less than zero.

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