NameValueCollection Constructor (Int32, IEqualityComparer)

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

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

public:
NameValueCollection(
	int capacity, 
	IEqualityComparer^ equalityComparer
)

Parameters

capacity
Type: System::Int32
The initial number of entries that the NameValueCollection object can 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.

ExceptionCondition
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.
