POInstantiating thread method from a different class in c#
text
Body
copied!<p>Can someone point me how to deal with the following issue? Basically, im trying to reuse code from the following example found at: <a href="http://www.codeproject.com/KB/threads/SynchronizationContext.aspx" rel="nofollow">http://www.codeproject.com/KB/threads/SynchronizationContext.aspx</a> the only issue i dont understand is how i can instantiate the RUN method if it is found in a different class. Please see following code.</p> <pre><code>public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void mToolStripButtonThreads_Click(object sender, EventArgs e) { // let's see the thread id int id = Thread.CurrentThread.ManagedThreadId; Trace.WriteLine("mToolStripButtonThreads_Click thread: " + id); // grab the sync context associated to this // thread (the UI thread), and save it in uiContext // note that this context is set by the UI thread // during Form creation (outside of your control) // also note, that not every thread has a sync context attached to it. SynchronizationContext uiContext = SynchronizationContext.Current; // create a thread and associate it to the run method Thread thread = new Thread(Run); // start the thread, and pass it the UI context, // so this thread will be able to update the UI // from within the thread thread.Start(uiContext); } // THIS METHOD SHOULD GO IN A DIFFERENT CLASS (CLASS2) SO HOW TO CALL METHOD UpdateUI() private void Run(object state) { // lets see the thread id int id = Thread.CurrentThread.ManagedThreadId; Trace.WriteLine("Run thread: " + id); // grab the context from the state SynchronizationContext uiContext = state as SynchronizationContext; for (int i = 0; i < 1000; i++) { // normally you would do some code here // to grab items from the database. or some long // computation Thread.Sleep(10); // use the ui context to execute the UpdateUI method, // this insure that the UpdateUI method will run on the UI thread. uiContext.Post(UpdateUI, "line " + i.ToString()); } } /// <summary> /// This method is executed on the main UI thread. /// </summary> private void UpdateUI(object state) { int id = Thread.CurrentThread.ManagedThreadId; Trace.WriteLine("UpdateUI thread:" + id); string text = state as string; mListBox.Items.Add(text); } } </code></pre> <h2>EDIT:</h2> <p>for instance, the run method is given me by someone else (another developer) and i need to run this method as a different thread in my UI thread (Main Thread or class Form1), however, whenever i run the thread (run method) i also need to update a ListBox <code>mListBox</code> using the UpdateUI method.</p>
