OrderedDictionary Constructor (Int32, IEqualityComparer)

Initializes a new instance of the OrderedDictionary class using the specified initial capacity and comparer.

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

public OrderedDictionary(
	int capacity,
	IEqualityComparer comparer
)

Parameters

capacity
Type: System.Int32
The initial number of elements that the OrderedDictionary collection can contain.
comparer
Type: System.Collections.IEqualityComparer
The IComparer to use to determine whether two keys are equal.
-or-
null to use the default comparer, which is each key's implementation of Object.Equals.

The comparer determines whether two keys are equal. Every key in a OrderedDictionary collection must be unique. The default comparer is the key's implementation of Object.Equals.

The custom comparer enables such scenarios as doing lookups with case-insensitive strings.
