是否有方法强制将所有引用的程序集加载到应用程序域中?

这似乎起到了关键作用:

        var loadedAssemblies = AppDomain.CurrentDomain.GetAssemblies().ToList();
        var loadedPaths = loadedAssemblies.Select(a => a.Location).ToArray();

        var referencedPaths = Directory.GetFiles(AppDomain.CurrentDomain.BaseDirectory, "*.dll");
        var toLoad = referencedPaths.Where(r => !loadedPaths.Contains(r, StringComparer.InvariantCultureIgnoreCase)).ToList();
        toLoad.ForEach(path => loadedAssemblies.Add(AppDomain.CurrentDomain.Load(AssemblyName.GetAssemblyName(path))));

正如jon所指出的,理想的解决方案需要递归到每个已加载的程序集的依赖项中,但是在我的特定场景中,我不必担心它。

更新: .NET4中包含的托管扩展性框架(system.componentmodel)具有更好的工具来完成类似的事情。

你可以用 Assembly.GetReferencedAssemblies 得到一个 AssemblyName[] ,然后打电话 Assembly.Load(AssemblyName) 在他们每个人身上。当然,您需要重复执行-但最好跟踪已加载的程序集:)

只想共享一个递归示例。我在启动例程中调用loadReferencedAssembly方法,如下所示:

foreach (Assembly assembly in AppDomain.CurrentDomain.GetAssemblies())
{
    this.LoadReferencedAssembly(assembly);
}

这是递归方法:

private void LoadReferencedAssembly(Assembly assembly)
{
    foreach (AssemblyName name in assembly.GetReferencedAssemblies())
    {
        if (!AppDomain.CurrentDomain.GetAssemblies().Any(a => a.FullName == name.FullName))
        {
            this.LoadReferencedAssembly(Assembly.Load(name));
        }
    }
}

如果使用fody.costura或任何其他程序集合并解决方案,接受的答案将不起作用。

下面加载当前加载的任何程序集的引用程序集。递归留给您。

var loadedAssemblies = AppDomain.CurrentDomain.GetAssemblies().ToList();

loadedAssemblies
    .SelectMany(x => x.GetReferencedAssemblies())
    .Distinct()
    .Where(y => loadedAssemblies.Any((a) => a.FullName == y.FullName) == false)
    .ToList()
    .ForEach(x => loadedAssemblies.Add(AppDomain.CurrentDomain.Load(x)));

由于今天必须从特定路径加载一个程序集+依赖项,所以我编写了这个类来完成它。

public static class AssemblyLoader
{
    private static readonly ConcurrentDictionary<string, bool> AssemblyDirectories = new ConcurrentDictionary<string, bool>();

    static AssemblyLoader()
    {
        AssemblyDirectories[GetExecutingAssemblyDirectory()] = true;
        AppDomain.CurrentDomain.AssemblyResolve += ResolveAssembly;

    }

    public static Assembly LoadWithDependencies(string assemblyPath)
    {
        AssemblyDirectories[Path.GetDirectoryName(assemblyPath)] = true;
        return Assembly.LoadFile(assemblyPath);
    }

    private static Assembly ResolveAssembly(object sender, ResolveEventArgs args)
    {
        string dependentAssemblyName = args.Name.Split(',')[0] + ".dll";
        List<string> directoriesToScan = AssemblyDirectories.Keys.ToList();

        foreach (string directoryToScan in directoriesToScan)
        {
            string dependentAssemblyPath = Path.Combine(directoryToScan, dependentAssemblyName);
            if (File.Exists(dependentAssemblyPath))
                return LoadWithDependencies(dependentAssemblyPath);
        }
        return null;
    }

    private static string GetExecutingAssemblyDirectory()
    {
        string codeBase = Assembly.GetExecutingAssembly().CodeBase;
        var uri = new UriBuilder(codeBase);
        string path = Uri.UnescapeDataString(uri.Path);
        return Path.GetDirectoryName(path);
    }
}

另一个版本(基于 Daniel Schaffer 答案)在这种情况下,您可能不需要加载所有程序集,但需要预定义的程序集数量:

var assembliesToLoad = { "MY_SLN.PROJECT_1", "MY_SLN.PROJECT_2" };

// First trying to get all in above list, however this might not 
// load all of them, because CLR will exclude the ones 
// which are not used in the code
List<Assembly> dataAssembliesNames =
   AppDomain.CurrentDomain.GetAssemblies()
            .Where(assembly => AssembliesToLoad.Any(a => assembly.GetName().Name == a))
            .ToList();

var loadedPaths = dataAssembliesNames.Select(a => a.Location).ToArray();

var compareConfig = StringComparison.InvariantCultureIgnoreCase;
var referencedPaths = Directory.GetFiles(AppDomain.CurrentDomain.BaseDirectory, "*.dll")
    .Where(f =>
    {
       // filtering the ones which are in above list
       var lastIndexOf = f.LastIndexOf("\\", compareConfig);
       var dllIndex = f.LastIndexOf(".dll", compareConfig);

       if (-1 == lastIndexOf || -1 == dllIndex)
       {
          return false;
       }

       return AssembliesToLoad.Any(aName => aName == 
          f.Substring(lastIndexOf + 1, dllIndex - lastIndexOf - 1));
     });

var toLoad = referencedPaths.Where(r => !loadedPaths.Contains(r, StringComparer.InvariantCultureIgnoreCase)).ToList();

toLoad.ForEach(path => dataAssembliesNames.Add(AppDomain.CurrentDomain.Load(AssemblyName.GetAssemblyName(path))));

if (dataAssembliesNames.Count() != AssembliesToLoad.Length)
{
   throw new Exception("Not all assemblies were loaded into the  project!");
}
