The WPF calling thread cannot access this object because another thread owns the object, and the solution

1.WPF multithreaded Modification UI Example:

// Start thread Modify UI, throw exception ThreadPool.QueueUserWorkItem ((q) +=    {" Zhang San "null);

Solution: Modify the UI by using the Dispatcher.begininvoke+ delegate method

Encapsulating code that modifies the UI in a delegate

// Start thread processing New  true; // set to a background thread, the background thread exits automatically when the main thread ends, otherwise the program cannot end Thread1. Start ();

//threading methods, modifying button contentPrivate voidupdatebtn () {inti =0;  while(true) {i++; Action action1 = () + = {button. Content = i; }; button.        Dispatcher.begininvoke (Action1);         //If you do not set the wait, the entire program dies LoopThread.Sleep ( -); }}
