Parameters

capacity

The initial number of elements that the Queue can contain.

growFactor

The factor by which the capacity of the Queue is expanded.

Exception typeCondition

ArgumentOutOfRangeException

capacity is less than zero.

-or-

growFactor is less than 1.0 or greater than 10.0.

The capacity of a Queue is the number of elements the Queue can hold. As elements are added to a Queue, the capacity is automatically increased as required through reallocation. The capacity can be decreased by calling TrimToSize.

The growth factor is the number by which the current capacity is multiplied when a greater capacity is required. The growth factor is determined when the Queue is constructed. The capacity of the Queue will always increase by a minimum value, regardless of the growth factor; a growth factor of 1.0 will not prevent the Queue from increasing in size.

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 Queue.

This constructor is an O(n) operation, where n is capacity.
