关于多线程传递参数调用方法
学习完多线程通信方法，界面再也不会卡死了，但是项目中有级联反应，需要传递参数调度线程。
一级级联：
private void Window_Loaded(object sender, RoutedEventArgs e) { Thread thread = new Thread(new ThreadStart(GetProjectList)); thread.IsBackground = true; thread.Start(); } private void GetProjectList() { //Raw data ProjectList = GetProject(); //从主 UI 线程派生的后台线程不能更新的内容 Button UI 线程上创建。 为了使后台线程访问的内容属性的 Button, ，后台线程必须将工作委托给 Dispatcher 与 UI 线程关联 Action action = () => { cbProject.ItemsSource = ProjectList; cbProject.SelectedIndex = 0; }; if (System.Threading.Thread.CurrentThread != cbProject.Dispatcher.Thread) { cbProject.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, action); } else { action(); } }
二级级联：
private void cbProject_SelectionChanged(object sender, SelectionChangedEventArgs e) { string Project = cbProject.SelectedValue.ToString(); if(string.IsNullOrEmpty(Project) || Project.Equals("Project")) { return; } Thread thread = new Thread(new ParameterizedThreadStart(GetWaferNoList)); thread.IsBackground = true; thread.Start(Project); }
（参数类型需要object）
private void GetWaferNoList(object strProj) { WaferList=GetWaferList(); Action action = () => { cbWaferNo.ItemsSource = WaferList; cbWaferNo.SelectedIndex = 0; cbWaferNo.IsEnabled = true; lblWafer.Content = string.Empty; btnGenerate.IsEnabled = true; cbProject.IsEnabled = true; }; if (System.Threading.Thread.CurrentThread != cbWaferNo.Dispatcher.Thread) { cbWaferNo.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, action); } else { action(); } }
