推荐答案

您只能添加对.NET和COM dll的引用. 我认为dll是C或C ++.将

You can only add a reference to .NET and COM dlls.
I assume the dll is C or C++. Add

using System.Runtime.InteropServices

添加到.cs文件的顶部.
您将需要在想要使用的dll中创建所有功能的C#版本，并使用[DllImport("dllname.dll")]属性修饰它们-当然，请指定正确的dll名称.

to the top of the .cs file.
You will need to create C# versions of all functions in the dll you wish to use and decorate them with the [DllImport("dllname.dll")] attribute - specifying the correct dll name of course.
