ConcurrentStack<T>.IProducerConsumerCollection<T>.TryAdd(T) 方法

定义

尝试将一个对象添加到 IProducerConsumerCollection<T> 中。Attempts to add an object to the IProducerConsumerCollection<T>.

 virtual bool System.Collections.Concurrent.IProducerConsumerCollection<T>.TryAdd(T item) = System::Collections::Concurrent::IProducerConsumerCollection<T>::TryAdd;
bool IProducerConsumerCollection<T>.TryAdd (T item);
abstract member System.Collections.Concurrent.IProducerConsumerCollection<T>.TryAdd : 'T -> bool
override this.System.Collections.Concurrent.IProducerConsumerCollection<T>.TryAdd : 'T -> bool
Function TryAdd (item As T) As Boolean Implements IProducerConsumerCollection(Of T).TryAdd

参数

item
T

要添加到 IProducerConsumerCollection<T> 的对象。The object to add to the IProducerConsumerCollection<T>. 该值对于引用类型可以是空引用(在 Visual Basic 中为 Nothing)。The value can be a null reference (Nothing in Visual Basic) for reference types.

返回

Boolean

如果成功添加了对象,则为 true;否则为 falsetrue if the object was added successfully; otherwise, false.

实现

注解

对于 ConcurrentStack<T> ,此操作始终将对象插入到顶部 ConcurrentStack<T> ,并返回 true。For ConcurrentStack<T>, this operation will always insert the object onto the top of the ConcurrentStack<T> and return true.
