HashDictionary(Int32, Double, IEqualityComparer<K>, MemoryType)

Create a hash dictionary using a custom equalityComparer and prescribing the initial size of the dictionary and a non-default threshold for internal table expansion.

Declaration
public HashDictionary(int capacity, double fill, IEqualityComparer<K> keyequalityComparer, MemoryType memoryType = MemoryType.Normal)
Parameters
Type Name Description
System.Int32 capacity

The initial capacity. Will be rounded upwards to nearest power of 2, at least 16.
System.Double fill

The expansion threshold. Must be between 10% and 90%.
System.Collections.Generic.IEqualityComparer<K> keyequalityComparer

The external key equalitySCG.Comparer
MemoryType memoryType

The memory type of the enumerator used to iterate the collection
