SerializationException：类型未解决的成员" ..." [英] SerializationException: Type is not resolved for member "..."

问题描述

我一直在试图动态加载程序集到一个AppDomain。我需要做的，因为我想动态调用一个方法，但处理我的应用程序运行时不保持到DLL，因此，它可以更换，如果需要的话。但我得到这个SerializationException异常：类型未解决的成员...

下面是我的代码：

 的AppDomain域= AppDomain.CreateDomain（临时的AppDomain，空，AppDomain.CurrentDomain.SetupInformation）; 
尝试{
 obj对象= domain.CreateInstanceFromAndUnwrap（DllPath的，typeName的）; 
 IMyInterface的MyObj中=（IMyInterface的）目标文件; 
结果= myObj.MyMethod（东西）; 
} 
终于{
 AppDomain.Unload（域）; 
} 
  

解决方案

答：类型必须延长 MarshalByRefObject的。

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 "..."

Here's my code:

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);
}

解决方案

Answer: The type had to extend MarshalByRefObject.
