# PartyXblXboxUserIdToPlayFabEntityIdMapping

> PartyXblXboxUserIdToPlayFabEntityIdMapping 结构的参考，将 XBOX Live 用户 ID 与其链接的 PlayFab Party 实体 ID 配对。

XBOX Live 用户 ID 与 PlayFab 实体 ID 之间的映射。

## 语法

```cpp theme={null}
struct PartyXblXboxUserIdToPlayFabEntityIdMapping {  
    uint64_t xboxLiveUserId;  
    PartyString playfabEntityId;  
}  
```

### 成员

**`xboxLiveUserId`**   uint64\_t

XBOX Live 用户 ID。

**`playfabEntityId`**   [PartyString](/services/playfab/multiplayer/networking/reference/typedefs)

PlayFab 实体 ID。

在 XBOX Live 用户没有链接的 PlayFab 帐户的情况下，此值可能为空字符串。首次调用 [PartyXblManager::LoginToPlayFab](/services/playfab/multiplayer/networking/xblreference/classes/PartyXblManager/methods/partyxblmanager_logintoplayfab) 时会自动创建并链接一个 PlayFab 帐户。PlayFab SDK 提供的 **LoginWithXbox** API 也可用于链接帐户。
