ConcurrentStack<T>.PushRange Method (T[], Int32, Int32)

.NET Framework 4

Other Versions

.NET Framework 4.5

Inserts multiple objects at the top of the ConcurrentStack<T> atomically.

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

Syntax

C++

Copy

public void PushRange(
	T[] items,
	int startIndex,
	int count
)

Parameters

items: Type: T[]
The objects to push onto the ConcurrentStack<T>.

startIndex: Type: System.Int32
The zero-based offset in items at which to begin inserting elements onto the top of the ConcurrentStack<T>.

count: Type: System.Int32
The number of elements to be inserted onto the top of the ConcurrentStack<T>.

Exceptions

Exception	Condition
ArgumentNullException	items is a null reference (Nothing in Visual Basic).
ArgumentOutOfRangeException	startIndex or count is negative. Or startIndex is greater than or equal to the length of items.
ArgumentException	startIndex + count is greater than the length of items.

Remarks

When adding multiple items to the stack, using PushRange is a more efficient mechanism than using Push one item at a time. Additionally, PushRange guarantees that all of the elements will be added atomically, meaning that no other threads will be able to inject elements between the elements being pushed. Items at lower indices in the items array will be pushed before items at higher indices.
