This is a test code, the real business, LoopAsync is a file upload method, cannot pass CancellationToken, sometimes takes a long time, want to force to stop and stop, consult,

 
The static void Main (string [] args) 
{
Var timeoutCancellationTokenSource=new CancellationTokenSource (); 
DateTime currentDate=DateTime. Now; 
Console. WriteLine ($" beginning of the test: {currentDate: yyyyMMdd HH: mm: ss} "); 
Try 
{
_=Task. Run (()=& gt; 
{
For (int I=0; I & lt; 3; I++) 
{
Console. WriteLine ($" Cancel the countdown: {I} "); 
Task. Delay (1000). The Wait (); 
} 
TimeoutCancellationTokenSource. Cancel (); 
}); 
Var task=LoopAsync (/* timeoutCancellationTokenSource. Token */); 
Task. Wait (6 * 1000); 
} 
The catch (Exception ex) 
{
Console. WriteLine ($" test error: {ex. Message} "); 
} 
The finally 
{
Console. WriteLine ($" end of the test, available: {(DateTime. Now - currentDate). TotalSeconds} "); 
Console.ReadLine(); 
} 
} 

///& lt; Summary> 
///if you can't into CancellationToken here, so what are the way to stop the task 
///& lt;/summary> 
///& lt; Returns>  
Public static async Task LoopAsync (/* CancellationToken token=default */) 
{
For (int I=0; I & lt; 10000; I++) 
{
//if (token. IsCancellationRequested) 
//{
//the Console. WriteLine ($" LoopAsync: IsCancellationRequested "); 
//return; 
//} 
Console. WriteLine ($" LoopAsync: I={I} "); 
Await Task. Delay (1000); 
} 
return; 
}

LoopAsync is a third party to receive incoming Token to stop, also have no a ManualResetEvent to suspend,
Feel this link inside operation, is I understand is wrong?
