# RefCounted::Release

```cpp
void Release();
```

原子地减少引用计数。

**描述**

原子地减少引用计数。当引用计数归零时，对象会自动 `delete this`。这是实现自动内存管理的关键方法。

**线程安全：** ✅

**复杂度：** O(1)

**示例：**

```cpp
#include <XCEngine/Core/RefCounted.h>
#include <cstdio>

class MyObject : public XCEngine::Core::RefCounted {
public:
    void DoSomething() { }
};

int main() {
    MyObject* obj = new MyObject();
    printf("After create: %u\n", obj->GetRefCount());
    
    obj->AddRef();
    printf("After AddRef: %u\n", obj->GetRefCount());
    
    obj->Release();
    printf("After Release: %u\n", obj->GetRefCount());
    
    obj->Release();
    return 0;
}
```
