这个c++接口怎么转换为c#？？？

[zzyhost]

如下是文档给的c++接口，怎么用ｃ#声明？

short USER_API dc_SamAReadCardInfo  ( HANDLE  icdev,  
  int  type,  
  int *  text_len,  
  unsigned char *  text,  
  int *  photo_len,  
  unsigned char *  photo,  
  int *  fingerprint_len,  
  unsigned char *  fingerprint,  
  int *  extra_len,  
  unsigned char *  extra  
 ) 

这是我自己写的，不行，程序直接卡死退出
 [DllImport("dcrf32.dll")]
        private static extern short dc_SamAReadCardInfo(
            IntPtr handle,
            int type,
            out int text_len,
            out byte[] text,
            out int photo_len,
            out byte[] photo,
            out int fingerprint_len,
            out byte[] fingerprint,
            out int extra_len,
            out byte[] extra);

[杀马特丶蛮牛]

public static extern short dc_SamAReadCardInfo(System.IntPtr icdev, int type, ref int text_len, System.IntPtr text, ref int photo_len, System.IntPtr photo, ref int fingerprint_len, System.IntPtr fingerprint, ref int extra_len, System.IntPtr extra) ;

上面那个就可以了，还有种笨方法 你不确定 * 怎么写的时候 全用Intptr
