## WaitHandle::WaitAll(const System::ArrayPtr\<System::SharedPtr\<WaitHandle\>\>\&) method


等待所有句柄触发。

```cpp
static bool System::Threading::WaitHandle::WaitAll(const System::ArrayPtr<System::SharedPtr<WaitHandle>> &waitHandles)
```


| Parameter | Type | 描述 |
| --- | --- | --- |
| waitHandles | const System::ArrayPtr\<System::SharedPtr\<WaitHandle\>\>\& | 要等待的句柄。 |

### ReturnValue

当 waitHandles 中的每个元素都已收到信号时为 True；否则该方法永不返回。
