示例

下面的代码示例表示可重用 SocketAsyncEventArgs 对象的集合。

// Represents a collection of reusable SocketAsyncEventArgs objects.
class SocketAsyncEventArgsPool
{
    Stack<SocketAsyncEventArgs> m_pool;

    // Initializes the object pool to the specified size
    //
    // The "capacity" parameter is the maximum number of
    // SocketAsyncEventArgs objects the pool can hold
    public SocketAsyncEventArgsPool(int capacity)
    {
        m_pool = new Stack<SocketAsyncEventArgs>(capacity);
    }

    // Add a SocketAsyncEventArg instance to the pool
    //
    //The "item" parameter is the SocketAsyncEventArgs instance
    // to add to the pool
    public void Push(SocketAsyncEventArgs item)
    {
        if (item == null) { throw new ArgumentNullException("Items added to a SocketAsyncEventArgsPool cannot be null"); }
        lock (m_pool)
        {
            m_pool.Push(item);
        }
    }

    // Removes a SocketAsyncEventArgs instance from the pool
    // and returns the object removed from the pool
    public SocketAsyncEventArgs Pop()
    {
        lock (m_pool)
        {
            return m_pool.Pop();
        }
    }

    // The number of SocketAsyncEventArgs instances in the pool
    public int Count
    {
        get { return m_pool.Count; }
    }
}

注解

调用此构造函数后，所有属性都将具有其默认值：

• 对象引用将为 null

• 返回整数的属性将返回零。

• 属性 LastOperation 将等于 None。

• 属性 SendPacketsFlags 将等于 TransmitFileOptions.UseDefaultWorkerThread，它指定不使用任何标志。

• 属性 SocketFlags 将等于 None。

调用方必须先设置适当的属性，然后才能将对象传递到相应的异步套接字 (xxxAsync) 方法。
