ManualResetEventSlim Class
Provides a slimmed down version of ManualResetEvent.
Assembly: mscorlib (in mscorlib.dll)
| Name | Description | |
|---|---|---|
![]() | ManualResetEventSlim() | Initializes a new instance of the ManualResetEventSlim class with an initial state of nonsignaled. |
![]() | ManualResetEventSlim(Boolean) | Initializes a new instance of the ManualResetEventSlim class with a Boolean value indicating whether to set the intial state to signaled. |
![]() | ManualResetEventSlim(Boolean, Int32) | Initializes a new instance of the ManualResetEventSlim class with a Boolean value indicating whether to set the intial state to signaled and a specified spin count. |
| Name | Description | |
|---|---|---|
![]() | IsSet | Gets whether the event is set. |
![]() | SpinCount | Gets the number of spin waits that will occur before falling back to a kernel-based wait operation. |
![]() | WaitHandle | Gets the underlying WaitHandle object for this ManualResetEventSlim. |
| Name | Description | |
|---|---|---|
![]() | Dispose() | Releases all resources used by the current instance of the ManualResetEventSlim class. |
![]() | Dispose(Boolean) | Releases the unmanaged resources used by the ManualResetEventSlim, 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 the default hash function. (Inherited from Object.) |
![]() | GetType() | |
![]() | MemberwiseClone() | |
![]() | Reset() | Sets the state of the event to nonsignaled, which causes threads to block. |
![]() | Set() | Sets the state of the event to signaled, which allows one or more threads waiting on the event to proceed. |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
![]() | Wait() | Blocks the current thread until the current ManualResetEventSlim is set. |
![]() | Wait(CancellationToken) | Blocks the current thread until the current ManualResetEventSlim receives a signal, while observing a CancellationToken. |
![]() | Wait(Int32) | Blocks the current thread until the current ManualResetEventSlim is set, using a 32-bit signed integer to measure the time interval. |
![]() | Wait(Int32, CancellationToken) | Blocks the current thread until the current ManualResetEventSlim is set, using a 32-bit signed integer to measure the time interval, while observing a CancellationToken. |
![]() | Wait(TimeSpan) | Blocks the current thread until the current ManualResetEventSlim is set, using a TimeSpan to measure the time interval. |
![]() | Wait(TimeSpan, CancellationToken) | Blocks the current thread until the current ManualResetEventSlim is set, using a TimeSpan to measure the time interval, while observing a CancellationToken. |
You can use this class for better performance than ManualResetEvent when wait times are expected to be very short, and when the event does not cross a process boundary. ManualResetEventSlim uses busy spinning for a short time while it waits for the event to become signaled. When wait times are short, spinning can be much less expensive than waiting by using wait handles. However, if the event does not become signaled within a certain period of time, ManualResetEventSlim resorts to a regular event handle wait.
The following example shows how to use a ManualResetEventSlim. For more information about the use of SpinCount and other best practices concerning the use of this type, see ManualResetEvent and ManualResetEventSlim.

All public and protected members of ManualResetEventSlim are thread-safe and may be used concurrently from multiple threads, with the exception of Dispose, which must only be used when all other operations on the ManualResetEventSlim have completed, and Reset, which should only be used when no other threads are accessing the event.
