//Struct需要在C#裡重新定義一個Struct

//unsigned char** ppImage替換成IntPtr ppImage
//int& nWidth替換成ref int nWidth
//int*, int&, 則都可用 ref int 對應
//雙針指型別引數，可以用 ref IntPtr
//函式指標使用c++: typedef double (*fun_type1)(double); 對應 c#:public delegate double fun_type1(double);
//char* 的操作c++: char*; 對應 c#:StringBuilder;
//c#中使用指標:在需要使用指標的地方 加 unsafe
//unsigned char對應public byte
