c# – 取消任务

CancellationTokenSource tokenSource2 = new CancellationTokenSource();

CancellationToken token2 = tokenSource2.Token;


Task task2 = new Task(() =>
{
    for (int i = 0; i < int.MaxValue; i++)
    {
        token2.ThrowIfCancellationRequested();
        Thread.Sleep(100);
        Console.WriteLine("Task 2 - Int value {0}",i);
    }
},token2);

task2.Start();

Console.WriteLine("Press any key to cancel the task");
Console.ReadLine();

tokenSource2.Cancel();
Console.WriteLine("Task 2 cancelled? {0}",task2.IsCanceled);

我期望Console.WriteLine(“任务2取消？{0}”,task2.IsCanceled);将打印**“任务2取消？真”**,但它打印“假”.

你知道发生了什么吗？这是预期的行为吗？谢谢.

编辑：确保在调用取消请求之前未完成任务.我添加了Console.ReadLine().
