使用CancellationTokenSource取消任务
代码语言：javascript复制CancellationTokenSource Source = new CancellationTokenSource();
Task T = Task.Factory.StartNew(() =>
{
//如果Token被取消
while (!Source.IsCancellationRequested)
{
Thread.Sleep(100);
Console.WriteLine("当前Thread正在运行{0}", Thread.CurrentThread.ManagedThreadId);
}
}, Source.Token);
Thread.Sleep(1000);
Source.Cancel(); 取消的回调方法
代码语言：javascript复制 CancellationTokenSource Source = new CancellationTokenSource();
Source.Token.Register(() =>
{
Console.WriteLine("当前的Source已经被取消");
});
Task T = Task.Factory.StartNew(() =>
{
while (!Source.IsCancellationRequested)
{
Thread.Sleep(100);
Console.WriteLine("当前Thread正在运行{0}", Thread.CurrentThread.ManagedThreadId);
}
}, Source.Token);
Thread.Sleep(1000);
Source.Cancel();延时取消
代码语言：javascript复制CancellationTokenSource Source = new CancellationTokenSource();
Source.Token.Register(() =>
{
Console.WriteLine("当前的Source已经被取消");
});
Task T = Task.Factory.StartNew(() =>
{
while (!Source.IsCancellationRequested)
{
Thread.Sleep(100);
Console.WriteLine("当前Thread正在运行{0}", Thread.CurrentThread.ManagedThreadId);
}
}, Source.Token);
//延时取消
Source.CancelAfter(new TimeSpan(0, 0, 0, 5));取消的组合
代码语言：javascript复制 //只要一个被取消，comineSource的组合就被取消，类似于WhenAny
CancellationTokenSource Source = new CancellationTokenSource();
Source.Cancel();
CancellationTokenSource Source2 = new CancellationTokenSource();
//comineSource 里面只要有一个被取消了，comineSource的状态就被取消
var comineSource = CancellationTokenSource.CreateLinkedTokenSource(Source.Token, Source2.Token);
Console.WriteLine("s1={0},s2={1},s3={2}", Source.IsCancellationRequested, Source2.IsCancellationRequested, comineSource.IsCancellationRequested);
