This article describes the internal members of the System.Threading.Tasks.Task class that help you implement a custom debugger. For general information about this class, see the Task reference article.
Namespace: System.Threading.Tasks
Assembly: mscorlib (in mscorlib.dll)
Because you can't access these internal members from the .NET Framework, the following syntax is provided in Common Intermediate Language (CIL).
Syntax
.class public auto ansi System.Threading.Tasks.Task
extends System.Object
implements System.Threading.IThreadPoolWorkItem,
System.IAsyncResult,
System.IDisposable,
System.Threading.ICancelableOperation
Members
Methods
| Name | Description |
|---|---|
| SetNotificationForWaitCompletion Method | Sets or clears the TASK_STATE_WAIT_COMPLETION_NOTIFICATION state bit. |
| NotifyDebuggerOfWaitCompletion Method | Placeholder method used as a breakpoint target by the debugger. |
Fields
| Name | Description |
|---|---|
| m_action | The delegate that represents the code to execute in the Task object. |
| m_contingentProperties | Stores additional properties of the Task object. |
| m_parent | The backing field for the System.Threading.Tasks.Task parent property. |
| m_stateFlags | Stores information about the current state of the Task object. |
| m_stateObject | An object that represents data that will be used by the action. |
| m_taskId | The backing field for the System.Threading.Tasks.Task.Id property. |
| s_taskIdCounter | The next available identifier for a Task object. |
| TASK_STATE_CANCELED | Indicates that the task canceled before it reached the running state, or that the task confirmed its cancellation and completed without exception. |
| TASK_STATE_EXECUTED | Indicates that the task is running. |
| TASK_STATE_FAULTED | Indicates that the task completed because of an unhandled exception. |
| TASK_STATE_RAN_TO_COMPLETION | Indicates that the task completed execution successfully. |
| TASK_STATE_WAITING_ON_CHILDREN | Indicates that the task finished executing its delegate and is implicitly waiting for attached child tasks to finish. |
Remarks
The following internal methods are useful to a debugger engine because they mark the entrance to Task code execution:
