如何在运行时使外部程序集可用? [英] How to make an external assembly available at runtime?

问题描述

我在此处提问了显然问题是我可以使用Reflection的Assembly.LoadFile或Assembly.LoadFrom加载程序集，并在该程序集内获取类型，该程序集在整个应用程序中仍不可访问.因此，当WPF尝试解析类型时，它找不到该类型，因为它没有找到程序集.

I asked a question here and apparently the problem is where I can load an assembly using Reflection's Assembly.LoadFile or Assembly.LoadFrom, and get the type inside that assembly, the assembly is still not accessible in the whole application. So when WPF tries to resolve a type, it doesn't find that type because it doesn't find the assembly.

我的问题是，我可以在运行时引用程序集，以便WPF对其进行解析吗?

My question is, can I reference an assembly at runtime, so that it will be resolvable by WPF?

推荐答案

一个对我有用的解决方案是处理

A solution that works for me is handling the CurrentDomain.AssemblyResolve event

AppDomain.CurrentDomain.AssemblyResolve += 
    new ResolveEventHandler(OnAssemblyResolveFailure);

Assembly OnAssemblyResolveFailure(object sender, ResolveEventArgs args)
    {
        AssemblyName name = new AssemblyName(args.Name);
        Assembly assembly = .. //some logic here to load the assembly from assembly name
        return assembly;
    }

这样，如果应用程序无法解析程序集名称，它将调用您的处理程序来查找它

This way if the application cannot resolve an assembly name it will call your handler to find it
