# MatchmakingTicket.Cancel 方法

取消票證。

```csharp theme={null}
public void Cancel()
```

## 備註

此方法會將非同步作業排入佇列，以取消此配對票證。成功時，會提供 [`OnMatchmakingTicketCompleted`](/zh-TW/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/PlayFabMultiplayer/OnMatchmakingTicketCompleted)，表示票證已取消。

此方法不保證票證會被取消。票證可能在取消作業處理之前就已完成，或取消要求可能因網路或服務錯誤而失敗。如果取消嘗試失敗但可以重試，程式庫會繼續重試取消作業。否則，會提供 [`OnMatchmakingTicketCompleted`](/zh-TW/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/PlayFabMultiplayer/OnMatchmakingTicketCompleted)，表示票證已失敗。
