# XblMultiplayerMeasurementFailure

定义指示会话初始化期间服务质量 (QoS) 度量失败原因的值。

## 语法

```cpp theme={null}
enum class XblMultiplayerMeasurementFailure  : uint32_t  
{  
    Unknown,  
    None,  
    Timeout,  
    Latency,  
    BandwidthUp,  
    BandwidthDown,  
    Group,  
    Network,  
    Episode  
}  
```

## 常量

| 常量            | 说明                               |
| ------------- | -------------------------------- |
| Unknown       | 未知度量失败。                          |
| None          | 无度量失败。                           |
| Timeout       | 度量超时。                            |
| Latency       | 延迟度量失败。                          |
| BandwidthUp   | 上行（对等方到主机）带宽度量失败。                |
| BandwidthDown | 下行（主机到对等方）带宽度量失败。                |
| Group         | 此玩家的度量失败，因为该组中另一名玩家的度量失败。        |
| Network       | 由于网络错误导致度量失败；例如无法访问该玩家。          |
| Episode       | 度量失败，因为初始化情节失败。这可能是因为会话中没有足够的用户。 |
