菜鸟求助:C#调用c++dll问题(嵌套结构)

Question

可以定义的用那个什么Marshas什么的

Answer 1

Red说的是这样么?
            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 80)]
              public RGBCOLOR[] m_Color;

                //得到产品指针

编译config为:0x0......
请问怎么将getProdInfo(config)返回的产品配置信息数据区按照c中的结构解析?
真心求助,希望得到大家的帮助,谢谢!

用unsafe fixed模式可能会解决些问题
