# PartyChatControl::GetEntityId

> 取得與此聊天控制項相關聯之使用者的 PlayFab 實體識別碼。

取得與此聊天控制項相關聯之使用者的 PlayFab 實體識別碼。

## 語法

```cpp theme={null}
PartyError GetEntityId(  
    PartyString* entityId  
)  
```

### 參數

**`entityId`**   [PartyString\*](/zh-TW/services/playfab/multiplayer/networking/reference/typedefs)\
*library-allocated output*

輸出的實體識別碼。

### 傳回值

PartyError

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

## 備註

傳回的字串與代表該實體之 `PFEntityKey` 結構的 *id* 欄位中的值相同。[GetEntityType()](/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyChatControl/methods/partychatcontrol_getentitytype) 傳回的值則代表 `PFEntityKey` 的另一半。 <br /><br /> 實體識別碼字串的記憶體在聊天控制項的存留期間內保持有效，也就是直到 [PartyManager::StartProcessingStateChanges()](/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_startprocessingstatechanges) 提供其 [PartyChatControlDestroyedStateChange](/zh-TW/services/playfab/multiplayer/networking/reference/structs/partychatcontroldestroyedstatechange) 和/或 [PartyDestroyChatControlCompletedStateChange](/zh-TW/services/playfab/multiplayer/networking/reference/structs/partydestroychatcontrolcompletedstatechange) (視發生的終結類型而定)，且所有參考該聊天控制項的狀態變更都已傳回給 [PartyManager::FinishProcessingStateChanges()](/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_finishprocessingstatechanges) 為止。
