Stack(Of T) Constructor (Int32)
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Initializes a new instance of the Stack(Of T) class that is empty and has the specified initial capacity or the default initial capacity, whichever is greater.
Assembly: System (in System.dll)
Parameters
- capacity
- Type: System.Int32
The initial number of elements that the Stack(Of T) can contain.
| Exception | Condition |
|---|---|
| ArgumentOutOfRangeException | capacity is less than zero. |
The capacity of a Stack(Of T) is the number of elements that the Stack(Of T) can hold. As elements are added to a Stack(Of T), 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(Of T).
The capacity can be decreased by calling TrimExcess.
This constructor is an O(n) operation, where n is capacity.
