## ICallbackStartEndOperations class


旨在用于在方法开始前和结束后必须执行某些逻辑的场景。需要由必须继承 [ICallbackOperationParams](../icallbackoperationparams/) 接口的类定义 [StartCallbackOperation(ICallbackOperationParams)](../) 和 [EndCallbackOperation(ICallbackOperationParams)](../) 的参数。

```cpp
class ICallbackStartEndOperations : public virtual System::Object
```

## 方法
