跨目录的AppDomain依赖项

时间：2010-12-24 14:31:30

标签： c# plugins appdomain

我正在创建一个插件系统，我正在为每个插件创建一个AppDomain。每个插件都有自己的目录及其主要程序集和引用。除了我的接口程序集之外，我的插件加载器将加载主程序集（因此插件可以与应用程序交互）。

创建AppDomain：

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

加载程序集：

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

var assemblies = new List<Assembly>();

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

assemblyName的格式是程序集的文件名，不带“.dll”。

问题是AppDomain.Load(assemblyName)抛出异常：

  

无法加载文件或程序集'[[assemblyName]]，Version = 1.0.0.0，Culture = neutral，PublicKeyToken = null'或其依赖项之一。系统找不到指定的文件。

[[assemblyName]]的所有依赖关系都是：

  1. 在目录pluginPath内，
  2. 已加载的myInterfaceAssembly或
  3. 在GAC（例如mscorelib）。

    4. 显然我没有做对。我试过了：

    1. 使用this.appDomain.CreateInstanceAndUnwrap继承MarshalByRefObject并使用LoadAssembly方法创建对象以加载程序集。我得到一个异常，说当前程序集（包含代理类）无法加载（找不到文件，如上所述），即使我手动调用this.appDomain.Load(Assembly.GetExecutingAssembly().GetName(true))。
    2. 将AssemblyResolve处理程序附加到this.appDomain。我遇到了与（1）中相同的异常，并且手动加载没有帮助。
    3. 首先通过将其依赖项加载到this.appDomain来递归加载程序集。这不起作用，但我怀疑我的代码是否正确：
      4. 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));
}

      如何在插件目录中加载我的插件程序集及其依赖项，同时还在当前目录中加载一些程序集？

      注意：插件可能（可能会）引用的程序集已经加载到当前域中。如果需要，可以跨域共享（性能优势？简单性？）。

答案 0 :(得分：9)

我再次尝试了一个尝试过的解决方案：

  

使用this.appDomain.CreateInstanceAndUnwrap继承MarshalByRefObject并使用LoadAssembly方法创建对象以加载程序集。我得到一个例外，说明当前程序集（包含代理类）无法加载（找不到文件，如上所述），即使我手动调用this.appDomain.Load(Assembly.GetExecutingAssembly().GetName(true))。

我发现CreateInstanceFromAndUnwrap可以接受汇编文件的路径，这使事情变得简单：

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);
    }
}

这解决了我的AppDomain创建问题。 （现在让其他一切工作！）

感谢大家的帮助;我非常感谢您的投入。

答案 1 :(得分：3)

我相信当尝试将程序集加载到主AppDomain而不是您明确创建的域时，会发生异常。这是使用AppDomain.Load的副作用，导致程序集被加载到当前域和您创建的域中。由于程序集仅在您创建的域的bin路径（插件目录）中，因此您将获得异常。

来自与AppDomain.Load相关的MSDN：

  

将程序集加载到两者中   域，因为汇编没有   派生自MarshalByRefObject，和   因此负载的返回值   方法无法编组。代替，   公共语言运行库尝试   将程序集加载到调用中   应用领域。

答案 2 :(得分：2)

我有类似的问题。您需要自定义用于查找程序集的方法。可能需要修改Console.Debug语句以进行编译，但这是一般要点：

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";
    string exeName = partialName + ".exe";

    string searchDirectory = "locationOfDirectoryToSearch";
    // Add other directories that you want to search here


    List<string> directorySearch = new List<string>
    {
      CombinePath(searchDirectory, dllName),
      CombinePath(searchDirectory, exeName),
      // Include the other directories here to this list adding both the dll and exe.
    };

    foreach (string fileName in directorySearch)
    {
      if (File.Exists(fileName))
      {
