Struct需要在C#里重新定义一个Struct
CallBack回调函数需要封装在一个委托里，delegate static extern int FunCallBack(string str);
nsigned char** ppImage替换成IntPtr ppImage
nt& nWidth替换成ref int nWidth
nt*, int&, 则都可用 ref int 对应
双针指类型参数，可以用 ref IntPtr
函数指针使用c++: typedef double (*fun_type1)(double); 对应 c#:public delegate double fun_type1(double);
char* 的操作c++: char*; 对应 c#:StringBuilder;
c#中使用指针:在需要使用指针的地方 加 unsafe
unsigned char对应public byte
