C# 已将程序集加载到AppDomain，但获取无法加载文件或程序集异常

我正在尝试动态加载一些程序集，如下所示：

using (var svc = new MyClient()) // MyClient is proxy to a WCF service
{
    var bytecode = svc.GetAssembly();
    var assembly = Assembly.Load(bytecode);
    var dependencies = svc.GetDependencies();
    foreach (var dependency in dependencies)
    {
        Assembly.Load(dependency.Bytecode);
        Console.WriteLine("loaded {0}", asm.FullName);
    }
    var type = assembly.GetExportedTypes().First();
    var ctor = type.GetConstructor(new Type[0]);
    var obj = ctor.Invoke(new object[0]);    // get an exception here
}

但是，当调用ctor，CLR尝试加载依赖程序集时，我会遇到一个异常。我已将依赖项加载到for循环中的应用程序域中。如何修复此异常

我通过处理AppDomain.CurrentDomain.AssemblyResolve解决了一个类似的问题：

AppDomain.CurrentDomain.AssemblyResolve += AssemblyResolve;

private static Assembly AssemblyResolve(object sender, ResolveEventArgs args)
{
    return AppDomain.CurrentDomain.GetAssemblies().FirstOrDefault(a => a.FullName == args.Name);
}

这要求已加载所有依赖项。

堆栈跟踪表明缺少Asm2。您能否检查Asm2程序集是否在此目录中：f:/Client/bin/Debug/您想做什么？我已经编写了许多动态加载程序集和实例化类型的应用程序。这显然是一个依赖性问题，其中Asm2与加载它的项目有关。Asm2不在该目录中。我已经在for循环中将其加载到应用程序域中。还使用Console.WriteLine进行了验证。CLR应针对已加载的程序集进行绑定，而不是搜索文件系统。这就是我想要完成的，我在问。我认为你应该把它复制到那里，以确保这是当前的问题，然后反向工作，看看为什么它试图“再次”加载它。它是否正在寻找旧版本的Asm（1.0.0.0）？使用Assembly.Load（字节[]）？CLR不应该与那个绑定。太好了！进行了此修改：私有静态程序集AssemblyResolve（对象发送方，ResolveEventArgs args）{return AppDomain.CurrentDomain.GetAssemblys（）。其中（a=>a.FullName==args.Name）。SingleOrDefault（）；}
