如果不添加dll引用，如何从VB.net调用C＃方法 [英] Without adding dll reference, how to call C# method from VB.net

问题描述

我有C＃dll包含方法。

我需要在运行时加载这个dll而不添加引用并从VB.net调用C＃方法。

I have C# dll which contains method .
I need to load this dll on runtime without adding reference and call C# method from VB.net.

推荐答案

虽然您可以使用反射来执行此操作，但它很慢并且容易出现故障：如果目标DLL被删除或更改，则当您尝试使用它来调用该方法时，您的应用程序将会失败。这可能为时已晚：您可能会丢失用户数据。



这是一个很多，更好的想法使用一个引用：方法和它的必需参数然后在编译时检查，它会工作，或者当你的应用程序试图启动时你会收到无法找到的错误。



有充分的理由吗强迫自己反思？如果可以避免这种情况通常不是一个好主意。

While you can use reflection to do this, it's slow, and prone to failure: if the target DLL is removed or changed, your app will fail when it tries to use it to call the method. This is likely to be too late: you can lose user data.

It's a lot, lot better idea to use a reference: the method and it's required parameters are then checked at compile time, and it will work, or you will get a "could not be found" error when you application tries to start.

Is there a good reason for forcing yourself into reflection? It's not normally a good idea if it can be avoided.
