Examples

The following code example represents a collection of reusable SocketAsyncEventArgs objects.

// 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; }
    }
}

Remarks

After calling this constructor all properties will have their default values:

• Object references will be null

• Properties that return an integer will return zero.

• The LastOperation property will be equal to None.

• The SendPacketsFlags property will be equal to TransmitFileOptions.UseDefaultWorkerThread, which specifies no flags will be used.

• The SocketFlags property will be equal to None.

The caller must set the appropriate properties prior to passing the object to the appropriate asynchronous socket (xxxAsync) method.
