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

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.

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

public:
NameValueCollection(
	int capacity,
	NameValueCollection^ col
)

Parameters

capacity
Type: System::Int32

The initial number of entries that the NameValueCollection can contain.

col
Type: System.Collections.Specialized::NameValueCollection^

The NameValueCollection to copy to the new NameValueCollection instance.

Exception Condition
ArgumentOutOfRangeException

capacity is less than zero.

ArgumentNullException

col is null.

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(n) operation, where n is capacity. If the number of elements in col is greater than capacity, this constructor becomes an O(n + m) operation, where n is capacity and m is the number of elements in col.
