Set Time Out duration for requested association for C-Echo / C-Store

In the API Documentation, the DicomClient constructonr lets you set the AssociationRequestTimeoutInMs via the DicomClientOptions hope this helps!

Thanks for reply....
I did used it and found that default Association Request Time Out duration is 5000 ms. I have added the Eventhandler with client as

        client.AssociationRequestTimedOut += (sender, e) =>
        {
            UpdateServerStatus($"Association requested for server time out: "+e.String());
        };

But even after no response from server after 5 sec. this event handler is not getting accessed by program. But also the system.exception error is getting logged as Exception thrown: 'System.Net.Sockets.SocketException' in System.dll.
So is it that where it is not allowing and exiting the current thread.
Also is there a way to cancel a request sent by client because in some discussions I have read that C-Cancel is not supported by fo-dicom.

Maybe A-Abort?

Take a look at this class: Tests/FO-DICOM.Tests/Network/Client/DicomClientTimeoutTests.cs
This are the unit tests about timeouts in clients. There you also find a method that tests the AssociationRequestTimeout:

fo-dicom/Tests/FO-DICOM.Tests/Network/Client/DicomClientTimeoutTests.cs

Line 620 in b45ffe1

public async Task AssociationRequestTimeOutExceptionShouldThrowAfterMaxRetry()

Basically, you have to wrap your await client.SendAsync() in a try-catch-block and catch the DicomAssociationRequestTimeOutException instead of only adding a handler to the event. You should catch all exceptions, also the SocketException.

You also can cancel requests. You can pass a CancellationToken as parameter to client.SendAsync(cancellationToken).
