Barrier Class
Enables multiple tasks to cooperatively work on an algorithm in parallel through multiple phases.
Assembly: System (in System.dll)
The Barrier type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Barrier(Int32) | Initializes a new instance of the Barrier class. |
![]() | Barrier(Int32, Action<Barrier>) | Initializes a new instance of the Barrier class. |
| Name | Description | |
|---|---|---|
![]() | CurrentPhaseNumber | Gets the number of the barrier's current phase. |
![]() | ParticipantCount | Gets the total number of participants in the barrier. |
![]() | ParticipantsRemaining | Gets the number of participants in the barrier that haven’t yet signaled in the current phase. |
| Name | Description | |
|---|---|---|
![]() | AddParticipant | Notifies the Barrier that there will be an additional participant. |
![]() | AddParticipants | Notifies the Barrier that there will be additional participants. |
![]() | Dispose() | Releases all resources used by the current instance of the Barrier class. |
![]() | Dispose(Boolean) | When overridden in a derived class, releases the unmanaged resources used by the Barrier, and optionally releases the managed resources. |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | RemoveParticipant | Notifies the Barrier that there will be one less participant. |
![]() | RemoveParticipants | Notifies the Barrier that there will be fewer participants. |
![]() | SignalAndWait() | Signals that a participant has reached the Barrier and waits for all other participants to reach the barrier as well. |
![]() | SignalAndWait(CancellationToken) | Signals that a participant has reached the Barrier and waits for all other participants to reach the barrier, while observing a CancellationToken. |
![]() | SignalAndWait(Int32) | Signals that a participant has reached the Barrier and waits for all other participants to reach the barrier as well, using a 32-bit signed integer to measure the timeout. |
![]() | SignalAndWait(TimeSpan) | Signals that a participant has reached the Barrier and waits for all other participants to reach the barrier as well, using a TimeSpan to measure the time interval. |
![]() | SignalAndWait(Int32, CancellationToken) | Signals that a participant has reached the barrier and waits for all other participants to reach the barrier as well, using a 32-bit signed integer to measure the timeout, while observing a CancellationToken. |
![]() | SignalAndWait(TimeSpan, CancellationToken) | Signals that a participant has reached the Barrier and waits for all other participants to reach the barrier as well, using a TimeSpan to measure the time interval, while observing a CancellationToken. |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
A group of tasks cooperate by moving through a series of phases, where each in the group signals it has arrived at the Barrier in a given phase and implicitly waits for all others to arrive. The same Barrier can be used for multiple phases.

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: Synchronization | ExternalThreading. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes. |
