# ThreadIndex

> Gets the index for the current thread when executing a job, otherwise 0.

## Definition

* **Type:** Property
* **Namespace:** [Unity.Jobs.LowLevel.Unsafe](/engine/6000.3/script-reference/unity/jobs/lowlevel/unsafe.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public static int ThreadIndex { get; }
```

### Remarks

When multiple threads are executing jobs, no two threads have the same index. The range of this property is `[0, Unity.Jobs.LowLevel.Unsafe.JobsUtility.ThreadIndexCount)`. The value returned when used from within a job is the same as the value stored in job members decorated with `[Unity.Collections.LowLevel.Unsafe.NativeSetThreadIndexAttribute]`.
