# Handle

> Gets native handle of the ProfilerMarker.

## Definition

* **Type:** Property
* **Namespace:** [Unity.Profiling](/engine/6000.6/script-reference/unity/profiling.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public nint Handle { get; }
```

### Remarks

Use *Handle* to obtain a native marker handle and extend funtionality of [ProfilerMarker](/engine/6000.6/script-reference/unity/profiling/profilermarker.md).
