# NativeArrayUnsafeUtility

> Contains unsafe methods for working with NativeArray instances.

## Definition

* **Type:** Class
* **Namespace:** [Unity.Collections.LowLevel.Unsafe](/engine/6000.7/script-reference/unity/collections/lowlevel/unsafe.md)
* **Assembly:** UnityEngine.ManagedKernelModule

```csharp
public static class NativeArrayUnsafeUtility
```

## Remarks

This class contains methods that you can use to perform unsafe operations that ignore the job safety system. For example, if you are implementing your own [custom native container](/engine/6000.7/manual/scripting/optimization/job-system/thread-safe-types/custom-nativecontainer.md), you might want to call `NativeArray` methods that cause the safety system to produce errors, even though you're implementing these methods safely. `NativeArrayUnsafeUtility` allows you to perform these operations without triggering errors in the safety system.
