示例1: QueueExplore
public void QueueExplore()
{
var queue = new Queue<string>();
queue.Enqueue("1");
queue.Enqueue("2");
Assert.That(queue.Dequeue(), Is.EqualTo("1"));
Assert.That(queue.Count, Is.EqualTo(1));
queue.Enqueue("3");
// you CAN loop through a queue as it implements IEnumerable
foreach (var number in queue)
{
Console.WriteLine(number);
}
// original queue would have memory for 3, decrease it to only use 2 (same as count)
queue.TrimExcess();
}示例2: Main
static void Main(string[] args)
{
Queue<DateTime> aq = new Queue<DateTime>();
aq.Enqueue(new DateTime(2008, 1, 19)); // item 1
aq.Enqueue(new DateTime(2008, 4, 5)); // item 2
aq.Enqueue(new DateTime(2008, 7, 2)); // item 3
aq.Enqueue(new DateTime(2008, 12, 3)); // item 4
Console.WriteLine("Count: {0}", aq.Count);
PrintValues(aq);
// Peek item 1 but do not remove
DateTime item = aq.Peek();
Console.WriteLine("Peek: {0}", item.ToShortDateString()); // item is DateTime, not object
PrintValues(aq);
// Contains
Boolean contains = aq.Contains(new DateTime(2008, 7, 2));
Console.WriteLine("Contains: {0}", contains);
// Remove items
DateTime item1 = aq.Dequeue();
DateTime item2 = aq.Dequeue();
Console.WriteLine("Dequeue: {0} {1}", item2.ToShortDateString(), item2.ToShortDateString());
PrintValues(aq);
Console.WriteLine("Count: {0}", aq.Count);
// Trim to size
aq.TrimExcess(); // c.f. TrimToSize in non-generic Queue
// iterate through Queue using a Queue.Enumerator
Console.WriteLine("Listing using Queue.Enumerator");
Queue<DateTime>.Enumerator qenum = aq.GetEnumerator(); // Queue<T>.Enumerator is a public inner struct declared in Queue<t>, see MyClass in this project for similar example
while (qenum.MoveNext())
{
DateTime dt = qenum.Current;
Console.WriteLine("{0}", dt.ToShortDateString());
}
}示例3: DequeueFrom
private ConcurrencyBehavior.IWaiter DequeueFrom(Queue<ConcurrencyBehavior.IWaiter> queue)
{
ConcurrencyBehavior.IWaiter waiter = queue.Dequeue();
if (queue.Count == 0)
{
queue.TrimExcess();
}
return waiter;
}示例4: TrimExcess
public void TrimExcess(int items, int capacity)
{
var q = new Queue<int>(capacity);
for (int i = 0; i < items; i++)
{
q.Enqueue(i);
}
q.TrimExcess();
Assert.Equal(items, q.Count);
Assert.Equal(Enumerable.Range(0, items), q);
}示例5: Undo
internal static void Undo( Player player, Command command ) {
if( player.UndoBuffer.Count > 0 ) {
// no need to set player.drawingInProgress here because this is done on the user thread
Logger.Log( "Player {0} initiated /undo affecting {1} blocks (on world {2})", LogType.UserActivity,
player.Name,
player.UndoBuffer.Count,
player.World.Name );
player.MessageNow( "Restoring {0} blocks...", player.UndoBuffer.Count );
Queue<BlockUpdate> redoBuffer = new Queue<BlockUpdate>();
while( player.UndoBuffer.Count > 0 ) {
BlockUpdate newBlock = player.UndoBuffer.Dequeue();
BlockUpdate oldBlock = new BlockUpdate( null, newBlock.X, newBlock.Y, newBlock.H,
player.World.Map.GetBlock( newBlock.X, newBlock.Y, newBlock.H ) );
player.World.Map.QueueUpdate( newBlock );
redoBuffer.Enqueue( oldBlock );
}
player.UndoBuffer = redoBuffer;
redoBuffer.TrimExcess();
player.MessageNow( "Type /undo again to reverse this command." );
Server.RequestGC();
} else {
player.MessageNow( "There is currently nothing to undo." );
}
