如何加载一个wpf exe并在同一个进程和appdomain中通过反射启动它？

Question

我正在使用 TinyJitHook https://github.com/Elliesaur/TinyJitHook 来修补已编译的可执行文件。

我想加载一个 wpf exe 文件并运行它在 c# 控制台程序中；

wpf程序默认为空window of visual studio.

主程序是控制台程序；

当我运行主程序时，出现“无法定位资源 'mainwindow.xaml'”错误。

我该怎么办

感谢发表“Process.Start("WpfApp1.exe")”评论的人，这会启动程序，但似乎不会在一个进程或 AppDomain 中生成它们。

主应用程序

public static void Main(string[] args)
{
    string filePath = @"WpfApp1.exe";

    Assembly asm = Assembly.LoadFrom(filePath);
    MainJitHook hook = new MainJitHook(asm, IntPtr.Size == 8);
    hook.OnCompileMethod += ChangeExample;

    hook.Hook();
    try
    {
        MethodInfo method = asm.EntryPoint;
        method.Invoke(null, new object[] { });
    }
    catch (Exception extInfo)
    {
        Console.WriteLine(extInfo.ToString());
    }

    hook.Unhook();
    Console.WriteLine("DONE");
    Console.ReadKey();
}


private static unsafe void ChangeExample(MainJitHook.RawArguments args, Assembly relatedAssembly, uint methodToken, ref byte[] ilBytes1, ref byte[] ehBytes1)
{
    try
    {
        var methodBase = relatedAssembly.ManifestModule.ResolveMethod((int) methodToken);
        Console.WriteLine("###################### cur method is " + methodBase.Name + " asm fiel is " + relatedAssembly.GetName());
    } catch (Exception ex)
    {
        Console.WriteLine(ex.ToString());
    }
}

App.xaml

             StartupUri="MainWindow.xaml">
    <Application.Resources>
         
    </Application.Resources>
</Application>

MainWindow.xaml

</Window>

如果您有一个已编译的 WPF 应用程序可执行文件，您可以在单独的进程中使用 Process.Start API 到运行它：

System.Diagnostics.Process.Start(@"WpfApp1.exe");
