Value

A System.Threading.WaitHandle that is signaled when an asynchronous operation completes. [Edit]

Remarks

Operation

The object returned by IAsyncResult.AsyncWaitHandle can be allocated in advance or on demand. However, once allocated it is required to be kept alive until the user calls a method that ends the asynchronous operation, such as System.IO.FileStream.EndRead(IAsyncResult). Only after the operation completes or is canceled, can the object be disposed of.

Note: WaitHandle supplies methods that support waiting for synchronization objects to become signaled, such as System.Threading.WaitHandle.WaitOne(int, bool) .

This property is read-only.

Usage

Clients that wait for the operation to complete (as opposed to polling), use this property to obtain a synchronization object to wait on.
