C#异步计数器的使用

1、

  CancellationTokenSource cancellationToken = new CancellationTokenSource();      
  public void InitData()
  {
      cancellationToken.Token.Register(() => { Name = "被取消了"; });
      int count = 0;
      Task.Run( () => {
          while (!cancellationToken.IsCancellationRequested)
          {
              Name += $"{count}一直在执行...";
              System.Console.WriteLine("一直在执行...");
              Thread.Sleep(1000);
              count++;
          }
      });

      cancellationToken.CancelAfter(5000);
  }

2、也可以写成

  CancellationTokenSource cancellationToken = new CancellationTokenSource();      
  public void InitData()
  {
      cancellationToken.Token.Register(() => { Name = "被取消了"; });
      int count = 0;
      Task.Run(async () => {
          while (!cancellationToken.IsCancellationRequested)
          {
              Name += $"{count}一直在执行...";
              System.Console.WriteLine("一直在执行...");
               await Task.Delay(1000);
              count++;
          }
      });

      cancellationToken.CancelAfter(5000);
  }
