启动窗体上不存在WPF触发事件

本文关键字：事件 WPF 不存在 窗体 启动 | 更新日期: 2023-09-27 18:01:24

我的WPF应用程序中有一些表单。我在app。xaml中指定了启动表单假设它是 form A

当应用程序启动时，我的其他表单的事件像

一样触发
  • 组合框选择改变
  • 复选框已选中更改

我只想打开表单A，不想让其他表单事件触发。有什么简单的方法可以防止这些事件发生吗?

这是我的app。xaml

<Application x:Class="MMS.UI.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:sys="clr-namespace:System;assembly=mscorlib"
             xmlns:local="clr-namespace:MMS.UI"
             StartupUri="FormAcilis.xaml">
    <!--<Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Themes/Metro/Metro.MSControls.Core.Implicit.xaml" />
                <ResourceDictionary Source="Themes/Metro/Metro.MSControls.Toolkit.Implicit.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>-->
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
                <ResourceDictionary Source="/Resources/Icons.xaml" />
            </ResourceDictionary.MergedDictionaries>
            <local:NullToBooleanConverter x:Key="ntb"/>
            <local:NullToVisibilityConverter x:Key="ntv"/>
            <local:NullToBooleanRevConverter x:Key="ntbr"/>
            <BooleanToVisibilityConverter x:Key="btv" />
            <local:BooleanToVisibilityRevConverter x:Key="btvr"/>
            <local:GroupsToTotalConverter x:Key="gtt"/>
            <local:GroupsToTotalConverter2 x:Key="gtt2"/>
            <local:DurumToBooleanConverter x:Key="dtb"/>
            <local:DurumToBooleanConverterRev x:Key="dtbr"/>
            <local:DosyalarToPathConverter x:Key="dtp"/>
            <Style x:Key="RightAligned" TargetType="TextBlock">
                <Setter Property="HorizontalAlignment" Value="Right"/>
            </Style>
        </ResourceDictionary>
    </Application.Resources>
</Application>

这是app。example。cs

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);
        }
    }
}

我没有尝试打开任何其他表单。但是他们的事件还在触发

启动窗体上不存在WPF触发事件

好吧，我知道我错了，这是因为一个函数初始化其他形式像这样:

  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;
            }

我想知道我的项目有哪些窗口。抱歉我的英语不好。你的建议对我有帮助。
