### Remarks

You can only access the native array as long as the the buffer memory has not been reallocated. Several dynamic buffer operations, such as [DynamicBuffer\<T>.Add](/engine/7000.0/script-reference/unity/entities/dynamicbuffer1/add.md) and [DynamicBuffer\<T>.TrimExcess](/engine/7000.0/script-reference/unity/entities/dynamicbuffer1/trimexcess.md) can result in buffer reallocation.
