在运行时引用.dll？

Question

If you observe the following picture, my 'RSR.exe' application runs perfectly fine as the two .dlls are located on the same file-path; however, if those 2 .dlls are not located on the same file path/directory as the RSR.exe, it will result in a crash/'program has stopped working'.

Here is the following piece of code I am trying to use with no success.

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);
    }

Here is the following picture of the crash information when the 2 .dlls are not located within the same directory/path.

Any assistance would be appreciated.

Thanks.

If you must package your DLL as embedded resource you can load it through dynamic assembly resolve. Your code must run permission to load as well.

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;
}
