# MatchmakingTicket.Cancel 方法

取消票证。

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

## 备注

此方法将一个异步操作加入队列以取消该匹配票证。成功时,将提供 [`OnMatchmakingTicketCompleted`](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/PlayFabMultiplayer/OnMatchmakingTicketCompleted),指示该票证已被取消。

此方法不保证票证一定会被取消。票证可能在取消处理之前就已完成,或者取消请求可能因网络或服务错误而失败。如果取消尝试失败但可重试,库将继续重试取消操作。否则,将提供 [`OnMatchmakingTicketCompleted`](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/PlayFabMultiplayer/OnMatchmakingTicketCompleted),指示该票证已失败。
