public class AsyncSemaphore : IDisposable
type AsyncSemaphore = class

Remarks

This semaphore guarantees FIFO ordering.

This object does *not* need to be disposed of, as it does not hold unmanaged resources. Disposing this object has no effect on current users of the semaphore, and they are allowed to release their hold on the semaphore without exception. An ObjectDisposedException is thrown back at anyone asking to or waiting to enter the semaphore after Dispose() is called.

Constructors

AsyncSemaphore(Int32)

Initializes a new instance of the AsyncSemaphore class.

Properties

CurrentCount

Methods

Dispose()

Faults all pending semaphore waiters with ObjectDisposedException and rejects all subsequent attempts to enter the semaphore with the same exception.

Dispose(Boolean)

Disposes managed and unmanaged resources held by this instance.

EnterAsync(CancellationToken)

Requests access to the lock.

EnterAsync(Int32, CancellationToken)

Requests access to the lock.

EnterAsync(TimeSpan, CancellationToken)
