Public method GetAccessControl Gets the access control security for a named system semaphore.
Public method Supported by Portable Class Library GetHashCode Serves as the default hash function. (Inherited from Object.)
Public method GetLifetimeService Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Public method Supported by Portable Class Library GetType Gets the Type of the current instance. (Inherited from Object.)
Public method InitializeLifetimeService Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Public method Static member Supported by Portable Class Library OpenExisting(String) Opens the specified named semaphore, if it already exists.
Public method Static member OpenExisting(String, SemaphoreRights) Opens the specified named semaphore, if it already exists, with the desired security access.
Public method Supported by Portable Class Library Release() Exits the semaphore and returns the previous count.
Public method Supported by Portable Class Library Release(Int32) Exits the semaphore a specified number of times and returns the previous count.

Public method Static member TryOpenExisting(String, Semaphore) Opens the specified named semaphore, if it already exists, and returns a value that indicates whether the operation succeeded.
Public method Static member TryOpenExisting(String, SemaphoreRights, Semaphore) Opens the specified named semaphore, if it already exists, with the desired security access, and returns a value that indicates whether the operation succeeded.
Public method Supported by Portable Class Library WaitOne() Blocks the current thread until the current WaitHandle receives a signal. (Inherited from WaitHandle.)
Public method Supported by Portable Class Library WaitOne(Int32) Blocks the current thread until the current WaitHandle receives a signal, using a 32-bit signed integer to specify the time interval. (Inherited from WaitHandle.)
Public method Supported by Portable Class Library WaitOne(TimeSpan) Blocks the current thread until the current instance receives a signal, using a TimeSpan to specify the time interval. (Inherited from WaitHandle.)
Public method WaitOne(Int32, Boolean) Blocks the current thread until the current WaitHandle receives a signal, using a 32-bit signed integer to specify the time interval and specifying whether to exit the synchronization domain before the wait. (Inherited from WaitHandle.)
Public method WaitOne(TimeSpan, Boolean) Blocks the current thread until the current instance receives a signal, using a TimeSpan to specify the time interval and specifying whether to exit the synchronization domain before the wait. (Inherited from WaitHandle.)
