c# - MyApp.App不包含添加ResourceDictionary之后的初始化定义

一切正常，直到我添加资源字典。然后看起来像：

App.xaml：

<Application x:Class="MyApp.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
         xmlns:local="clr-namespace:MyApp.MyApp.Common">
<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>

        </ResourceDictionary.MergedDictionaries>
        <local:MainMenuButtonVisibilityConverter x:Key="MainMenuButtonVisibilityConverter" />  <!-- withoot this line is fine-->
    </ResourceDictionary>
</Application.Resources>

App.g.cs：

namespace MyApp {
...
    public static void Main() {
        MyApp.App app = new MyApp.App();
        app.InitializeComponent(); // <------ here is the problem
        app.Run();
    }
}

MainMenuButtonVisibilityConverter：

namespace MyApp.MyApp.Common
{
public class MainMenuButtonVisibilityConverter : IValueConverter
{
...
}}

我的错误：

Error   2   'MyApp.MyApp.App' does not contain a definition for 'InitializeComponent' and no extension method 'InitializeComponent' accepting a first argument of type 'MyApp.MyApp.App' could be found (are you missing a using directive or an assembly reference?)

我的项目名称：MyApp
包含ViewModels和Common的文件夹也经过校准：MyApp

添加资源字典时我做错了什么？

App.xaml.cs

namespace MyApp.MyApp
{
public partial class App : Application
{
    private Shell shell;
    private MyAppMain myAppMain;

    public App()
    {
    }

    private void Dispatcher_UnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e)
    {
        MessageBox.Show(e.Exception.Message, "", MessageBoxButton.OK, MessageBoxImage.Hand);
        e.Handled = true;
    }

    protected override void OnStartup(StartupEventArgs e)
    {
        base.OnStartup(e);
        base.Dispatcher.UnhandledException += new DispatcherUnhandledExceptionEventHandler(this.Dispatcher_UnhandledException);
        myAppMain = new MyAppMain("");
    }

}}

最佳答案

您是否尝试过更改声明的顺序？首先应在ResourceDictionary中声明转换器。

 <ResourceDictionary>
 <local:MainMenuButtonVisibilityConverter x:Key="MainMenuButtonVisibilityConverter" />  <!-- withoot this line is fine-->
        <ResourceDictionary.MergedDictionaries>

        </ResourceDictionary.MergedDictionaries>

    </ResourceDictionary>
