`public BulkTaskResult(BulkTaskState State, TResult? Result = default, Exception? Exception = null, DateTimeOffset? StartedAt = null, DateTimeOffset? FinalizedAt = null)` 

Represents the result of a bulk task execution. For tasks that have not finished, [BulkTaskResult<TResult>.Empty](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskResult-TResult/) is used.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `State` | `BulkTaskState` | The state of the task. |
| `Result` | `{TResult}` | If the task has completed with the status [BulkTaskState.Completed](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/), the result will be stored here; otherwise, it will be null. |
| `Exception` | `Exception` | If the task has completed with the status [BulkTaskState.Failed](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/), the exception will be stored here; otherwise, it will be null. |
| `StartedAt` | `Nullable<DateTimeOffset>` | The timestamp recorded when the task transitions to [BulkTaskState.Running](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/) and before task execution starts. |
| `FinalizedAt` | `Nullable<DateTimeOffset>` | The timestamp recorded after transitioning to [BulkTaskState.Completed](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/) or [BulkTaskState.Failed](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/), before the task result is returned. |

## Properties

`public BulkTaskState State { get; init; }` 

The state of the task.

`public TResult? Result { get; init; }` 

If the task has completed with the status [BulkTaskState.Completed](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/), the result will be stored here; otherwise, it will be null.

`public Exception? Exception { get; init; }` 

If the task has completed with the status [BulkTaskState.Failed](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/), the exception will be stored here; otherwise, it will be null.

`public DateTimeOffset? StartedAt { get; init; }` 

The timestamp recorded when the task transitions to [BulkTaskState.Running](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/) and before task execution starts.

`public DateTimeOffset? FinalizedAt { get; init; }` 

The timestamp recorded after transitioning to [BulkTaskState.Completed](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/) or [BulkTaskState.Failed](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/), before the task result is returned.

`public static BulkTaskResult<TResult> Empty { get; }` 

Gets a canonical result value for a task that has not yet started.

`public TimeSpan? Duration { get; }` 

Gets the elapsed time between task start and finalization.
