我正在寫output board 的program, 但是那output board給的DLL是C++ version , 請問各位大大, 我如何才能在C#調用這個DLL?因為我試過Add reference, visual studio 2003 有error message
"A reference to 'C:\game\bin\Debug\Dii.dll' could not be added. This is not a valid assemble or COM component. Only assemblies with extension 'dll'and COM components can be referenced. Please make sure that the file is accessible, and that it is a valid assembly or COM component.

好像是用DllImport引用一下所要使用的dll文件,然后声明一下需要使用的函数,好像就可以了,例子如下:

[DllImport("MyDll.dll",CharSet=CharSet.Auto)]

public static extern int GetNum(int Num);

請問大大, 若果個Dll 有個class 叫 calculation, 而calcutation 有個function 叫(int)"abc", 請問我如何能夠拿這個"abc" function 來用
