How to switch between streams in c # .net to update the GUI?

• 0
  I have a thread (not the main thread) that is working with treeView, so this is how I call the main thread to update the treeView
  
  I read about delegates, invoke ... I can't figure it out without an example yet.
  
  Something like this:
  
  Working in a background thread ....
  We switched to the main stream
  {
  treeView.items.add (item);
  }
  Working in a background thread ....

  Another option:
  

  this.Invoke(new Action(() =>
  
   {
  
      //  работа с treeView
  
  }));

  There may be several options. I remember it well like this:
  

  this.Invoke((MethodInvoker) delegate { 
  
    //
  
  });

  
  
  I don't see any point in InvokeRequired. In specifying a specific control instead of this - too.

  You can use SynchronizationContext
  
  Example:
  

  // Инициализируете в UI потоке
  
  synchContext = AsyncOperationManager.SynchronizationContext;
  
  // Затем из потоков
  
  synchContext.Post(OnComplete, data);
  
  // Где OnComplete уже будет выполняться в контексте UI

  And apply only when you understand what you are doing
  Control.CheckForIllegalCrossThreadCalls = False
