Question

我的WPF应用程序中有一些表单。我在App.xaml中指定了我的启动表单，让我们说表单A 。

当应用程序启动时，我的其他形式＆＃39;像

这样的事件

组合框选择已更改
复选框已更改

我只想打开表单A ，并且不希望其他表单事件触发。有没有简单的方法来防止这些事件被解雇？

好的，这是我的app.xaml

这是app.xaml.cs

＆＃13;

namespace MMS.UI
{
    /// <summary>
    /// Interaction logic for App.xaml
    /// </summary>
    public partial class App : Application
    {
        public App()
        {
            base.DispatcherUnhandledException += App_DispatcherUnhandledException;
        }

        void App_DispatcherUnhandledException(object sender, System.Windows.Threading.DispatcherUnhandledExceptionEventArgs e)
        {
            var ex = new CustomException(e.Exception, "Providers, App.xaml()");
        }

        protected override void OnStartup(StartupEventArgs e)
        {
            Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("tr-TR"); ;
            Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("tr-TR"); ;

            FrameworkElement.LanguageProperty.OverrideMetadata(
              typeof(FrameworkElement),
              new FrameworkPropertyMetadata(
                    XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag)));

            base.OnStartup(e);
        }
    }
}

我没有试图打开任何其他形式。但他们的事件仍然在解决。

好的，我认为我的不好，那是因为一个初始化其他形式的函数：

  List<MetroWindow> wndList = new List<MetroWindow>();
            try
            {
                Assembly uiProject = Assembly.Load("MMS"); 
                foreach (Type t in uiProject.GetTypes())
                {
                    if (t.BaseType == typeof(MetroWindow))
                    {
                        var emptyCtor = t.GetConstructor(Type.EmptyTypes);
                        if (emptyCtor != null)
                        {
                            MetroWindow f = (MetroWindow)emptyCtor.Invoke(new object[] { });
                            // t.FullName will help distinguish the unwanted entries and
                            // possibly later ignore them
                            wndList.Add(f);
                        }
                    }
                }
                return wndList;
            }
            catch (Exception err)
            {
                // log exception
                return null;
            }

我试图让我的项目有哪些窗口。抱歉英文不好。你的赞扬点亮了我的解决方案。
