如下是檔案給的c++介面，怎么用ｃ#宣告？
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
)
這是我自己寫的，不行，程式直接卡死退出
[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);
