Come impostare il gestore per webrequest.gettriponsesysync in IronRuby?

Question

Sto provando:

request = WebRequest.Create( uri )
responseTask = request.GetResponseAsync
action = Action.new { process_request( sender, e ) }
task = Task.new( action )
responseTask.Wait( TimeSpan.new( -1 ) )
responseTask.ContinueWith( task )

.

ma avere un errore seguente:

can't convert System::Threading::Tasks::Task into System::Action[System::Threading::Tasks::Task] (TypeError)  

.

UPD

on

responseTask = request.GetResponseAsync  
action = Action[Task].new { process_request( sender, e ) }  
responseTask.Wait( TimeSpan.new( -1 ) )  
responseTask.ContinueWith( action )  

.

Sto ricevendo questo errore:

Found multiple methods for 'ContinueWith': ContinueWith(System::Action[System::Threading::Tasks::Task]), ContinueWith(System::Action[System::Threading::Tasks::Task[System::Net::WebResponse]]) (System::Reflection::AmbiguousMatchException)

.

Answer 1

Continuewith prende un

Action<Task> 

.

e ha altri sovraccarichi, ma non per un'attività.

EG:

action = Action.new {Console.WriteLine("action")}
task = Task.new( action )
action2 = Action[Task].new{Console.WriteLine("action2")}
task.ContinueWith(action2)
task.Start()
#prints "action" then "action2".

IronRuby può lasciarti saltare specializzazioni tipo generico Era l'attività non generica, ecco la versione completamente digitata per il tuo problema:

 action = Action[Task[WebResponse]].new { process_request( sender, e ) }
