Зависимости AppDomain между каталогами

8 голосов
/ 24 декабря 2010

Я создаю систему плагинов и создаю один домен приложений на плагин. Каждый плагин имеет свой каталог со своими основными сборками и ссылками. Основные сборки будут загружаться моим загрузчиком плагинов, в дополнение к моим сборкам интерфейса (чтобы плагин мог взаимодействовать с приложением).

Создание домена приложения: 

this.appDomain = AppDomain.CreateDomain("AppDomain", null, new AppDomainSetup {
    ApplicationBase = pluginPath,
    PrivateBinPath = pluginPath,
});

Загрузка сборок: 

this.appDomain.Load(myInterfaceAssembly.GetName(true));

var assemblies = new List<Assembly>();

foreach (var assemblyName in this.assemblyNames) {
    assemblies.Add(this.appDomain.Load(assemblyName));
}

Формат assemblyName - это имя файла сборки без ".dll".

Проблема в том, что AppDomain.Load(assemblyName) выдает исключение:

Не удалось загрузить файл или сборку '[[assemblyName]], версия = 1.0.0.0, культура = нейтральная, PublicKeyToken = null' или одна из ее зависимостей. Система не может найти указанный файл.

Все зависимости [[assemblyName]]:

  1. Внутри каталога pluginPath,
  2. myInterfaceAssembly, который уже загружен, или
  3. В GAC (например, mscorelib).

Очевидно, я что-то не так делаю. Я пробовал:

  1. Создание объекта с использованием this.appDomain.CreateInstanceAndUnwrap, унаследованного от MarshalByRefObject с методом LoadAssembly для загрузки сборки. Я получаю исключение, говорящее, что текущая сборка (содержащая прокси-класс) не может быть загружена (файл не найден, как указано выше), даже если я вручную вызываю this.appDomain.Load(Assembly.GetExecutingAssembly().GetName(true)).
  2. Присоединение обработчика AssemblyResolve к this.appDomain. Меня встречает то же исключение, что и в (1), и загрузка вручную не помогает.
  3. Рекурсивная загрузка сборок путем загрузки их зависимостей в this.appDomain. Это не работает, но я сомневаюсь, что мой код правильный: 
private static void LoadAssemblyInto(AssemblyName assemblyName, AppDomain appDomain) {
    var assembly = Assembly.Load(assemblyName);

    foreach (var referenceName in assembly.GetReferencedAssemblies()) {
        if (!referenceName.FullName.StartsWith("MyProject")) {
            continue;
        }

        var loadedAssemblies = appDomain.GetAssemblies();

        if (loadedAssemblies.Any((asm) => asm.FullName == referenceName.FullName)) {
            continue;
        }

        LoadAssemblyInto(referenceName, appDomain);
    }

    appDomain.Load(assembly.GetName(true));
}

Как я могу загрузить свою сборку плагина с зависимостями в каталоге этого плагина, а также загрузить некоторые сборки в текущем каталоге?

Примечание: сборки, на которые плагин может (вероятно, будет ссылаться) уже загружены в текущем домене. Это может быть разделено между доменами (выигрыш в производительности? Простота?) При необходимости.

Я снова попробовал одно из своих попыток решения:

Создание объекта с использованием this.appDomain.CreateInstanceAndUnwrap наследования от MarshalByRefObject с методом LoadAssembly для загрузки сборки.Я получаю исключение, говорящее, что текущая сборка (содержащая прокси-класс) не может быть загружена (файл не найден, как указано выше), даже если я вручную вызываю this.appDomain.Load(Assembly.GetExecutingAssembly().GetName(true)).

. Я обнаружил, чтоCreateInstanceFromAndUnwrap может принять путь к файлу сборки, что упрощает задачу: 

private T CreateOnAppDomain<T>() {
    var type = typeof(T);

    return (T) this.appDomain.CreateInstanceFromAndUnwrap(
        type.Assembly.Location,
        type.FullName
    );
}

public void LoadAssemblies() {
    var assemblyLoader = CreateOnAppDomain<AssemblyLoader>();

    assemblyLoader.LoadAssembly(myInterfaceAssembly.GetName(true));

    foreach (var assemblyName in this.assemblyNames) {
        assemblyLoader.LoadAssembly(new AssemblyName(assemblyName));
    }
}

class AssemblyLoader : MarshalByRefObject {
    public void LoadAssembly(AssemblyName name) {
        Assembly.Load(name);
    }
}

Это решает мои проблемы с созданием AppDomain.(Теперь, чтобы все остальное работало!)

Спасибо за помощь всем;Я действительно ценю ваш вклад.

Я полагаю, что исключение возникает, когда он пытается загрузить сборку в основной AppDomain, а не в домен, который вы создали явно. Это побочный эффект использования AppDomain.Load, который приводит к загрузке сборки в текущий домен и созданный вами домен. Поскольку сборка находится только в каталоге bin (каталог подключаемых модулей) созданного вами домена, вы получаете исключение.

Из MSDN, относящегося к AppDomain.Load :

Сборка загружена в оба домены, потому что сборка не наследовать от MarshalByRefObject и поэтому возвращаемое значение Load метод не может быть маршалированным. Вместо, общеязыковая среда выполнения пытается загрузить сборку в вызов домен приложения.

У меня была похожая проблема. Вам нужно настроить метод, используемый для поиска сборок. Возможно, для компиляции операторы Console.Debug необходимо изменить, но вот общая суть: 

private static void SetupResolvingAdditionalThirdPartyDlls()
{
  AppDomain.CurrentDomain.AssemblyResolve += ResolveAssemblies;
}

private static Assembly ResolveAssemblies(object sender, ResolveEventArgs args)
{
  Assembly assembly = null;
  bool foundAssembly = false;

  Console.DebugFormat("Received request for the following dll {0}", args.Name);
  int idx = args.Name.IndexOf(',');
  if (idx > 0)
  {
    string partialName = args.Name.Substring(0, idx);
    string dllName = partialName + ".dll";
