# PFLobbyGetMemberProperty

> PFLobbyGetMemberProperty 参考，用于通过 PlayFab Multiplayer C++ SDK 按键读取 PlayFab 大厅上特定成员的自定义属性值。

根据键获取成员属性的值。

## 语法

```cpp theme={null}
HRESULT PFLobbyGetMemberProperty(  
    PFLobbyHandle lobby,  
    const PFEntityKey* member,  
    const char* key,  
    const char** value  
)  
```

### 参数

**`lobby`**   PFLobbyHandle

大厅的句柄。

**`member`**   [PFEntityKey\*](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmultiplayer/pfentitykey_clientsdk)

我们希望查询其属性包的成员。

**`key`**   char\*\
*is null-terminated*

属性的键。

**`value`**   char\*\*\
*library-allocated output, may return nullptr*

与键关联的输出值。输出为 null 值表示该属性不存在。

### 返回值

类型：HRESULT

如果调用成功，则为 `S_OK`；否则为错误代码。可通过 [PFMultiplayerGetErrorMessage()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmultiplayer/functions/pfmultiplayergeterrormessage) 检索错误代码的可读形式。

## 备注

每个成员的属性仅对大厅成员可见，或者在此为服务器拥有的大厅时对服务器可见。<br /><br /> 如果该成员仍处于通过 [PFMultiplayerCreateAndJoinLobby()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayercreateandjoinlobby)、[PFMultiplayerJoinLobby()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayerjoinlobby) 或 [PFLobbyAddMember()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pflobbyaddmember) 异步加入此大厅的过程中，则此方法将不返回任何属性。
