在主线程中执行Action <>(perform Action<> in main thread)

 我正在编写一个应用程序，它在后台执行很长的请求。 每次请求后我都需要将结果发送到主表单。 
 
 所以，这是一个代码： 
 
 Form1.cs的 
 
private async void StartButton_Click(object sender, EventArgs e)
{
    await Logic.GenerateStackAsync(stackSettings, delegate(FullOrder transaction)
          {
              lastOrderId.Text = transaction.OrderId;
          }
    );

    MessageBox.Show("Completed!");
}
 
 Logic.cs： 
 
    public static bool GenerateStack(StackSettings stackSettings, Action<FullOrder> onOrderCreated = null)
    {
         for(var i = 0; i < 10; i++) 
         {
              // long, long request, replaced with:
              System.Threading.Thread.Sleep(10000);
              if (onOrderCreated != null)
              {
                  onOrderCreated.Invoke(order);
                  // tried to change it with onOrderCreated(order), no results.
              }
          }

          return true;
    }

    public static Task<bool> GenerateStackAsync(StackSettings stackSettings, Action<FullOrder> onOrderCreated)
    {
        return TaskEx.Run(() => GenerateStack(stackSettings, onOrderCreated));
    }
 
 它抛出一个异常：“控制'lastOrderId'从一个线程访问，而不是它创建的线程。”，可以通过添加CheckForIllegalCrossThreadCalls = false;来修复CheckForIllegalCrossThreadCalls = false; ，但我认为这是一次糟糕的经历。 怎么做对了？ 先谢谢你。 
 
 PS抱歉英语不好。 

I'm writing an app, that performs very long requests at background. After each request I need to send result to main form.
 
So, here is a code:
 
Form1.cs
 
private async void StartButton_Click(object sender, EventArgs e)
{
    await Logic.GenerateStackAsync(stackSettings, delegate(FullOrder transaction)
          {
              lastOrderId.Text = transaction.OrderId;
          }
    );

    MessageBox.Show("Completed!");
}
 
Logic.cs:
 
    public static bool GenerateStack(StackSettings stackSettings, Action<FullOrder> onOrderCreated = null)
    {
         for(var i = 0; i < 10; i++) 
         {
              // long, long request, replaced with:
              System.Threading.Thread.Sleep(10000);
              if (onOrderCreated != null)
              {
                  onOrderCreated.Invoke(order);
                  // tried to change it with onOrderCreated(order), no results.
              }
          }

          return true;
    }

    public static Task<bool> GenerateStackAsync(StackSettings stackSettings, Action<FullOrder> onOrderCreated)
    {
        return TaskEx.Run(() => GenerateStack(stackSettings, onOrderCreated));
    }
 
It throws an exception: "Control 'lastOrderId' accessed from a thread other than the thread it was created on.", which can be fixed by adding CheckForIllegalCrossThreadCalls = false;, but I think that this is a bad experience. How make it right? Thank you in advance.
 
P.S. Sorry for bad English.
