BlockingCollection<T>.TryTake Method (T%, TimeSpan)

Tries to remove an item from the BlockingCollection<T> in the specified time period.

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

public bool TryTake(
	out T item,
	TimeSpan timeout
)

Parameters

item
Type: T%
The item to be removed from the collection.
timeout
Type: System.TimeSpan
An object that represents the number of milliseconds to wait, or an object that represents -1 milliseconds to wait indefinitely.

Return Value

Type: System.Boolean
true if an item could be removed from the collection within the specified time; otherwise, false.

ExceptionCondition
ObjectDisposedException

The BlockingCollection<T> has been disposed.

ArgumentOutOfRangeException

timeout is a negative number other than -1 milliseconds, which represents an infinite time-out.

-or-

timeout is greater than MaxValue.

InvalidOperationException

The underlying collection was modified outside of this BlockingCollection<T> instance.

The order in which an item is removed depends on the type of collection used to create the BlockingCollection<T> instance. When you create a BlockingCollection<T> object, you can specify the type of collection to use. For example, you could specify a ConcurrentConcurrentQueue object for first in, first out (FIFO) behavior, or a ConcurrentStack<T> object for last in, first out (LIFO) behavior. You can use any collection class that implements the IProducerConsumerCollection<T> interface. The default collection type for BlockingCollection<T> is ConcurrentQueue<T>.
