# PartyEndpoint::GetSharedProperty

> 取得共用屬性的值。

取得共用屬性的值。

## 語法

```cpp theme={null}
PartyError GetSharedProperty(  
    PartyString key,  
    PartyDataBuffer* value  
)  
```

### 參數

**`key`**   [PartyString](https://docs.xbox.com/zh-TW/services/playfab/multiplayer/networking/reference/typedefs.md)

要擷取之共用屬性的索引鍵。

**`value`**   [PartyDataBuffer\*](https://docs.xbox.com/zh-TW/services/playfab/multiplayer/networking/reference/structs/partydatabuffer.md)\
*輸出*

輸出結構，接收屬性值的指標以及值資料的長度 (以位元組為單位)。如果找不到屬性，呼叫會成功，但值為 nullptr 且位元組長度為 0。

### 傳回值

PartyError

`c_partyErrorSuccess` (如果呼叫成功)，否則為錯誤碼。可透過 [PartyManager::GetErrorMessage()](https://docs.xbox.com/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_geterrormessage.md) 擷取錯誤碼的人類可讀形式。

## 備註

如果沒有與該索引鍵相關聯的屬性，產生的值為 nullptr。傳回的值只在下一次呼叫 [PartyManager::StartProcessingStateChanges()](https://docs.xbox.com/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_startprocessingstatechanges.md) 之前有效。

## 需求

**標頭：** Party.h
