# XblMultiplayerManagerGameSessionPropertiesJson

以 JSON 字符串形式检索游戏会话的自定义属性。

## 语法

```cpp theme={null}
const char* XblMultiplayerManagerGameSessionPropertiesJson(  
)  
```

### 参数

### 返回值

类型：const char\*

指定游戏会话自定义属性的 JSON 字符串，如果游戏会话不存在则为 null。返回指针的内存在下次调用 [XblMultiplayerManagerDoWork](/reference/live/xsapi-c/multiplayer_manager_c/functions/xblmultiplayermanagerdowork) 之前保持有效。

## 备注

此函数检索游戏会话的自定义属性，以 JSON 字符串形式表示。可以随时更改这些自定义属性。如果自定义属性在多个设备之间共享，或可能同时由多个设备更新，请使用 [XblMultiplayerManagerGameSessionSetSynchronizedProperties](/reference/live/xsapi-c/multiplayer_manager_c/functions/xblmultiplayermanagergamesessionsetsynchronizedproperties) 函数来更改自定义属性。否则，你可以使用 [XblMultiplayerManagerGameSessionSetProperties](/reference/live/xsapi-c/multiplayer_manager_c/functions/xblmultiplayermanagergamesessionsetproperties) 函数来更改自定义属性。
