Android aseats 加密,Easy way to stop a task from executing after certain amount of time(Xamarin.Androi...

On button click I want to open a ProgressDialog which will show until a task is being executed, but I want to be able to stop the task even if it hasn't been completed after certain amount of time. I saw a lot of solutions on internet but they are very long. I want to know if there is an easier way.

here is my On Button Click event:

private async void Btn_Click(object sender, System.EventArgs e)

{

var mDialog = new ProgressDialog(this);

mDialog.SetMessage("Loading data...");

mDialog.SetCancelable(false);

mDialog.Show();

CancellationTokenSource cts = new CancellationTokenSource();

cts.CancelAfter(5000);

Task task = new Task(Foo, cts.Token);

task.Start();

int integer = await task;

mDialog.Dismiss();

txtView.Text = integer.ToString();

}

And here is my method which will execute in the task:

public int Foo()

{

System.Threading.Thread.Sleep(10000);

return 100;

}

Is it possible to stop the task at the 5th second of its execution without changing a lot the code I've just pasted, for example with only passing some time or object to the task's constructor, and also without making the Foo() method async
