[This is preliminary documentation and is subject to change.]
This class allows you to safely invoke a delegate asynchronously, similarly to calling
BeginInvoke(), without ever having to call EndInvoke(). Simply call AsyncHelper.QueueTaskToThreadPool()

This method allows you to safely invoke a delegate asynchronously, similarly to calling
BeginInvoke(), without ever having to call EndInvoke().
|
RemarksStarting with the 1.1 release of the .NET Framework, the SDK docs now carry a caution that mandates calling EndInvoke on delegates you've called BeginInvoke on in order to avoid potential leaks. This means you cannot simply "fire-and-forget" a call to BeginInvoke without the risk of running the risk of causing problems.
Examples
For example, assuming a delegate defined as follows:
CopyC#
Instead of doing this to fire-and-forget an async call to some
target method:
CopyC#
You would instead do this:
CopyC#
CopyC#delegate void CalcAndDisplaySumDelegate( int a, int b );
CopyC#CalcAndDisplaySumDelegate d = new CalcAndDisplaySumDelegate(someCalc.Add); d.BeginInvoke(2, 3, null);
CopyC#CalcAndDisplaySumDelegate d = new CalcAndDisplaySumDelegate(someCalc.Add); AsyncHelper.QueueTaskToThreadPool(d, 2, 3);
