# PFLobbyGetSearchProperty

> PFLobbyGetSearchProperty 参考，用于通过 PlayFab Multiplayer C++ SDK 大厅 API 按键读取 PlayFab 大厅上可搜索的属性值。

根据键获取搜索属性值。

## 语法

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

### 参数

**`lobby`**   PFLobbyHandle

**`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

搜索属性作为元数据对大厅的非成员可见，可用于过滤和排序大厅搜索结果。<br /><br /> 如果此大厅对象仍处于通过调用 [PFMultiplayerCreateAndJoinLobby()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayercreateandjoinlobby)、[PFMultiplayerCreateAndClaimServerLobby](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayercreateandclaimserverlobby)、[PFMultiplayerClaimServerLobby()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayerclaimserverlobby) 或 [PFMultiplayerJoinLobby()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayerjoinlobby) 异步创建、加入或领取的过程中，则此方法将不返回任何属性。
