Stack Constructor (ICollection)

Initializes a new instance of the Stack class that contains elements copied from the specified collection and has the same initial capacity as the number of elements copied.

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

public Stack(
	ICollection col
)

Parameters

col
Type: System.Collections.ICollection

The ICollection to copy elements from.

ExceptionCondition
ArgumentNullException

col is null.

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

The elements are copied onto the Stack 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.
