推荐答案

您应该与创建它的人交谈 - 他们应该提供技术支持，并且会比我们更了解他们的产品。如果没有，那就找另一个供应商并要求退款！



正如Dave所说，如果DLL文件不是.NET程序集，而是本机代码那么您不能将其添加为参考，而是必须使用P / Invoke：平台调用教程（C＃） [ ^ ]。

这不一定很简单：你需要非常小心地管理数据类型，以确保传递给API函数的是他们的期待 - 所以请仔细阅读函数文档和教程材料。

You should talk to the people who created it - they should provide technical support and will know more about their product than we will. If they don't, then find another supplier and demand your money back!

As Dave says, if the DLL file is not a .NET assembly but Native code then you cannot add it as a reference, you instead have to use P/Invoke: Platform Invoke Tutorial (C#)[^].
That's not necessarily simple: you need to be very careful to manage datatypes in particular to make sure that what you pass to the API functions are what they expect - so read both the documentation of the functions and the tutorial material very carefully.

除了 Griff 的答案之外，值得注意的是C＃样本是随Futronic SDK提供，请参见 Futronic Technology Company Limited [ ^ ]。

In addition to Griff's answer, it is worth noting C# samples are provided with the Futronic SDK, see Futronic Technology Company Limited[^].
