c# - 在运行时引用 .dll？

Question

如果您观察下图，我的“RSR.exe”应用程序运行良好，因为两个 .dll 位于同一文件路径上；但是，如果这 2 个 .dll 与 RSR.exe 不在同一文件路径/目录中，则会导致崩溃/“程序已停止工作”。

这是我尝试使用但没有成功的以下代码。

public static MainForm _mainForm;

    static string subPath = @"C:\Users\Public\Documents\RSR";

    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        if (!Directory.Exists(subPath))
        {
            Directory.CreateDirectory(subPath);

            if (IntPtr.Size == 4)
            {
                File.WriteAllBytes("C:\\Users\\Public\\Documents\\RSR\\MouseKeyboardActivityMonitor.dll", Properties.Resources.MouseKeyboardActivityMonitor);

                File.WriteAllBytes("C:\\Users\\Public\\Documents\\RSR\\WindowsFormsAero.dll", Properties.Resources.WindowsFormsAero);
            }
            else
            {
                File.WriteAllBytes("C:\\Users\\Public\\Documents\\RSR\\MouseKeyboardActivityMonitor.dll", Properties.Resources.MouseKeyboardActivityMonitor1);

                File.WriteAllBytes("C:\\Users\\Public\\Documents\\RSR\\WindowsFormsAero.dll", Properties.Resources.WindowsFormsAero);
            }
        }

        AssemblyName asm1 = AssemblyName.GetAssemblyName(@"C:\Users\Public\Documents\RSR\MouseKeyboardActivityMonitor.dll");
        Assembly.Load(asm1);

        AssemblyName asm2 = AssemblyName.GetAssemblyName(@"C:\Users\Public\Documents\RSR\WindowsFormsAero.dll");
        Assembly.Load(asm2);

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        using (_mainForm = new MainForm())
        {
            Application.Run(_mainForm);
        }

        Cursor normalCursor1 = new Cursor(new System.IO.MemoryStream(Properties.Resources.cursor_normal));
        SetSystemCursor(normalCursor1.Handle, 32512);
    }

这是当 2 个 .dll 不在同一目录/路径中时的崩溃信息的下图。

任何援助将不胜感激。

谢谢。

如果您必须将 DLL 打包为嵌入式资源，您可以通过动态程序集解析加载它。您的代码也必须运行加载权限。

public static MainForm _mainForm;
{ 
  //Add this in your main initialization   
  AppDomain.CurrentDomain.AssemblyResolve+=new ResolveEventHandler(CurrentDomain_AssemblyResolve);
}

private static Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
{
    if (args.Name.Contains("FullNameSpace.MouseKeyboardActivityMonitor"))
    {
        return Assembly.Load(Properties.Resources.MouseKeyboardActivityMonitor);
    }

    if (args.Name.Contains("FullNameSpace.MouseKeyboardActivityMonitor"))
    {
        return Assembly.Load(Properties.Resources.WindowsFormsAero);
    }

    return null;
}
