.NET:加载同一个 DLL 的两个版本 [英] .NET: Load two version of the same DLL

问题描述

我需要加载同一个 DLL 的两个版本，以便比较它们的输出.我假设我可以为此使用 AppDomains，但我需要一些指导.

I need to load two versions of the same DLL in order to compare their outputs. I assume that I can use AppDomains for this, but I need some guidence.

推荐答案

好吧，实际上比我想象的要容易得多.

Ok, it was actually a lot easier than I imagined.

    m_Assembly1 = Reflection.Assembly.LoadFile(IO.Path.Combine(System.Environment.CurrentDirectory, "Old Version\Some.dll"))
    m_Assembly2 = Reflection.Assembly.LoadFile(IO.Path.Combine(System.Environment.CurrentDirectory, "New Version\Some.dll"))

    Console.WriteLine("Old Version: " & m_Assembly1.GetName.Version.ToString)
    Console.WriteLine("New Version: " & m_Assembly2.GetName.Version.ToString)

    m_OldObject = m_Assembly1.CreateInstance("FullClassName")
    m_NewObject = m_Assembly2.CreateInstance("FullClassName")

从现在开始，我使用后期绑定和/或反射来运行我的测试.

From here on out I used late binding and/or reflection to run my tests.
