Я создаю систему плагинов, и я создаю один AppDomain для каждого плагина. У каждого плагина есть собственный каталог с его основными сборками и ссылками. Основные сборки будут загружены моим загрузчиком плагинов в дополнение к моим интерфейсным сборкам (чтобы плагин мог взаимодействовать с приложением).
Создание AppDomain:
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
- имя файла сборки без ". Я получаю исключение о том, 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))
.
AssemblyResolve
к this.appDomain
. Я встречался с тем же исключением, что и в (1), и загрузка вручную не помогает. 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 ее зависимостями в каталог этого плагина, одновременно загружая некоторые сборки в текущий каталог?
Примечание: сборки плагина могут (вероятно, будут) ссылки уже загружены в текущий домен. При необходимости его можно использовать в разных доменах (повышение производительности? Простота?).
