尝试在任务中嵌套任务以不阻止UI线程

Question

因此，我有一个发送服务调用的任务...该任务具有continuewith，以便在调用返回时程序可以整理数据。 现在，我还希望当调用返回数据时，它基于该数据进行另一个服务调用，而不会阻塞UI线程。 这可能吗？

到目前为止，我的示例代码是：

 Task t = new Task(() =>{//Make my service call};
 t.Start();
 t.ContinueWith((sender) =>
 {
     //sort my data out
     //when thats done make another service call based on that data that doesn't
     // block UI thread
 }, cts.Token, TaskContinuationOptions.OnlyOnRanToCompletion, TaskScheduler.FromCurrentSynchronizationContext());

Answer 1

如果有人想要更多有关如何执行此操作的信息：

void MyMethod()
{
    Task t = new Task(() =>{//Make my service call};
    t.Start();
    t.ContinueWith((sender) =>
    {
        //sort my data out
        //when thats done make another service call based on that data that doesn't
        // block UI thread

        BackgroundWorker bw = new BackgroundWorker();
        bw.DoWork += bw_DoWork;
        bw.RunWorkerAsync();
    }, cts.Token, TaskContinuationOptions.OnlyOnRanToCompletion, TaskScheduler.FromCurrentSynchronizationContext());
}

void bw_DoWork(object sender, DoWorkEventArgs e)
{
     //do some stuff
}
