[DllImport("icc_dll.dll",<br /> EntryPoint = "ICC15693_GetSystemInfo",<br /> CharSet = CharSet.Unicode,<br /> CallingConvention = CallingConvention.Winapi)]<br /> public static extern int ICC15693_GetSystemInfo(int iSid,ref ICC15693_VICC_INFO viccInfo);<br />上述方式即可加载DLL中的方法<br />对于指针参数,其实C#中只是屏蔽显示的指针调用,依然可以同过 ref obj来声明传引用调用。
