如何timout這項任務

Question

我打電話第三方庫的API 運行方法如下

await Task.Factory.StartNew(() => ThirdPartLibraryAPI.Run()); 

我想設置一些超時在此情況下，在這個API的時間太長。我怎樣才能做到這一點？

Answer 1

下面的代碼片段：

 var timeoutTask = Task.Delay(1500); 
     //using .ContinueWith(t => /*stuff to do on timeout*/); 
     //will cause the code to execute even if the timeout did not happen. 
     //remember that this task keeps running. we are just not waiting for it 
     //in case the worker task finishes first. 

     var workerTask = Task.Run(() => { ThirdPartLibraryAPI.Run() }); 
     var taskThatCompletedFirst = await Task.WhenAny(timeoutTask, workerTask); 

     //stuff to do on timeout can be done here 
     //if (taskThatCompletedFirst == timeoutTask) 

Answer 2

你可以使用這個片段

Task t = Task.Factory.StartNew(() => ThirdPartLibraryAPI.Run()); 
Task.WaitAny(t, miliseconds);
