Queue Constructor (ICollection)

Initializes a new instance of the Queue class that contains elements copied from the specified collection, has the same initial capacity as the number of elements copied, and uses the default growth factor.

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

public function Queue(
	col : ICollection
)

Parameters

col
Type: System.Collections.ICollection

The ICollection to copy elements from.

ExceptionCondition
ArgumentNullException

col is a null reference (Nothing in Visual Basic).

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 elements are copied onto the Queue in the same order they are read by the IEnumerator of the ICollection.

This constructor is an O(n) operation, where n is the number of elements in col.
