运行一个任务，做一些事情然后等待？

我熟悉任务、asyn/await 等的基础知识，但我没有做太多高级的事情，而且我有点陷入一个问题。我有一种与相机系统进行通信的方法。相机代码在其自己的线程上运行，使用Task.

    public Task<bool> DoCameraWork()
    {
       bool Result = true;

       return Task.Run<bool>(() =>
         {
             for (int i = 0; i < 10; i++)
             {
                 // Do something which will set Result to True or False

                 if (Result)
                     break;
                 else
                     Task.Delay(1000);
             }

            return Result;
         });
    }

我想要做的是启动任务（DoCameraWork），更新 UI，调用另一个方法，然后等待任务完成后再继续。

实现这一目标的最佳方法是什么？这是一个模拟方法，我希望能对其进行更多解释。是的，代码很差，但它只是为了解释我想要实现的目标。

// Running on UI Thread
public async void SomeMethod()
{
   DoCameraWork();  // If I do await DoCameraWork() then rest of code won't process untill this has completed

   TextBox.Text = "Waiting For camera work";
   SendData(); // Calls a method to send data to device on RS232, notthing special in this method 

   // Now I want to wait for the DoCameraWork Task to finish

   // Once camera work done, check result, update UI and continue with other stuff       

   // if result is true
   // TextBox.Text = "Camera work finished OK";
   // else if result is false
   // TextBox.Text = "Camera work finished OK";
   // Camera work finished, now do some more stuff
}

听起来您只想在该方法中稍后等待：

public async void SomeMethod()
{
   var cameraTask = DoCameraWork();

   TextBox.Text = "Waiting For camera work";
   SendData();

   var result = await cameraTask;
   TextBox.Text = result ? "Camera work finished OK"
                         : "Eek, something is broken";
   ...
}
