添加引用*.dll文件不成功，提示请确保此文件可访问并且是一个有效的程序集或COM组件。不知问题出在哪？

Question

添加引用*.dll文件不成功，提示请确保此文件可访问并且是一个有效的程序集或COM组件。查看该*.dll文件的属性都是可读可写的，只是语言为中文繁体。而我用的WIN7及VisualStudio2010都为中文简体版，不知跟这有没有关系？怎样才能正常引用该*.dll文件？

Answer 1

请问你引用的这个 *.dll 是 COM 组件吗？

Answer 2

不知道啊！是IC厂商提供的驱动文件。有2个文件，BridgeMini.cs/BridgeMini.dll总共不到80K，要不要发给你看看？

你把 BridgeMini.cs 中的代码稍微贴一些出来就行。

Answer 5

很好，你不需要做什么添加引用的操作了，只要 BridgeMini.dll 同你的程序集在同一个目录下就行。

注意 DllImport("BridgeMini.dll", 这类语句，你可以上 MSDN 了解下。

在你的程序中可以直接添加 BridgeMini.cs 文件，然后使用它提供的方法和类型。
