The ManualResetEventSlim type exposes the following members.

  NameDescription
Public methodManualResetEventSlim()Initializes a new instance of the ManualResetEventSlim class with an initial state of nonsignaled.
Public methodManualResetEventSlim(Boolean)Initializes a new instance of the ManualResetEventSlim class with a Boolean value indicating whether to set the intial state to signaled.
Public methodManualResetEventSlim(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.

  NameDescription
Public propertyIsSetGets whether the event is set.
Public propertySpinCountGets the number of spin waits that will be occur before falling back to a kernel-based wait operation.
Public propertyWaitHandleGets the underlying WaitHandle object for this ManualResetEventSlim.

  NameDescription
Public methodDispose()Releases all resources used by the current instance of the ManualResetEventSlim class.
Protected methodDispose(Boolean)When overridden in a derived class, releases the unmanaged resources used by the ManualResetEventSlim, and optionally releases the managed resources.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodResetSets the state of the event to nonsignaled, which causes threads to block.
Public methodSetSets the state of the event to signaled, which allows one or more threads waiting on the event to proceed.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodWait()Blocks the current thread until the current ManualResetEventSlim is set.
Public methodWait(CancellationToken)Blocks the current thread until the current ManualResetEventSlim receives a signal, while observing a CancellationToken.
Public methodWait(Int32)Blocks the current thread until the current ManualResetEventSlim is set, using a 32-bit signed integer to measure the time interval.
Public methodWait(TimeSpan)Blocks the current thread until the current ManualResetEventSlim is set, using a TimeSpan to measure the time interval.
Public methodWait(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.
Public methodWait(TimeSpan, CancellationToken)Blocks the current thread until the current ManualResetEventSlim is set, using a TimeSpan to measure the time interval, while observing a CancellationToken.

NoteNote

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.

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.
