NameObjectCollectionBase Constructor (Int32, IHashCodeProvider, IComparer)

Note: This API is now obsolete.

Initializes a new instance of the NameObjectCollectionBase class that is empty, has the specified 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 NameObjectCollectionBase(Int32, IEqualityComparer) instead.")>]
new : 
        capacity:int * 
        hashProvider:IHashCodeProvider * 
        comparer:IComparer -> NameObjectCollectionBase

Parameters

capacity
Type: System.Int32

The approximate number of entries that the NameObjectCollectionBase instance can initially contain.

hashProvider
Type: System.Collections.IHashCodeProvider

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

comparer
Type: System.Collections.IComparer

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

ExceptionCondition
ArgumentOutOfRangeException

capacity is less than zero.

The capacity of a NameObjectCollectionBase is the number of elements that the NameObjectCollectionBase can hold. As elements are added to a NameObjectCollectionBase, 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 NameObjectCollectionBase.

The hash code provider dispenses hash codes for keys in the NameObjectCollectionBase instance. 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.
