If it's registered in COM, you can simply add a COM reference in Visual Studio and Visual Studio will do all the Interop creation for you.

Assuming you use Visual Studio, in your Solution right click "references" and choose "Add Reference". Select your dll file.

In the classes that will use the dll, add : using MyLibrarysName;

then you can call the functions in that DLL using Mylibraryname.myfunction

Depending on the nature of the DLL, you can

  1. Add a reference to a registered COM DLL,

  2. Call Win32 DLLs with P/Invoke, or

  3. Write a wrapper in C++/CLI.

You would use an "extern" function, marked with the DllImport attribute.

[DllImport(@“C:\mylib.dll”)]
public static extern int myFunc(int param);
