SerializationException:未解析成员“..."的类型； [英] SerializationException: Type is not resolved for member "..."

问题描述

我一直在尝试将程序集动态加载到 AppDomain.我需要这样做，因为我想动态调用一个方法，但不要在我的应用程序运行时保留 DLL 的句柄，以便在需要时可以替换它.但是我收到了这个 SerializationException 异常:成员..."的类型未解析

I've been trying to dynamically load an assembly to an AppDomain. I need to do it because I want to call a method dynamically, but don't keep the handle to the DLL while my app is running, so that it can be replaced, if needed. But I'm getting this SerializationException exception: Type is not resolved for member "..."

这是我的代码:

AppDomain domain = AppDomain.CreateDomain("Temp AppDomain", null, AppDomain.CurrentDomain.SetupInformation);
try {
    object obj = domain.CreateInstanceFromAndUnwrap(dllPath, typeName);
    IMyInterface myObj = (IMyInterface) obj;
    result = myObj.MyMethod(something);
} 
finally {
    AppDomain.Unload(domain);
}

推荐答案

答案:类型必须扩展 MarshalByRefObject.

Answer: The type had to extend MarshalByRefObject.
