C# 调用 c++dll 参数为结构体 求大神指教

[xzm71908]

c++ dll代码如下：
#pragma pack(1)
//////////////////////////////////////////////////////////////////////////
typedef unsigned long bpf_u_int32;
struct pcap_pkthdr
{
struct timeval ts; /* time stamp */
bpf_u_int32 caplen; /* length of portion present */
bpf_u_int32 len; /* length this packet (off wire) */
};

typedef struct _proto_node
{
struct _proto_node *first_child;
struct _proto_node *last_child;
struct _proto_node *next;
struct _proto_node *parent;
char* protoinfo;

_proto_node()
{
first_child = NULL;
last_child = NULL;
next = NULL;
parent = NULL;
protoinfo = NULL;
};

} proto_node;

#define PAKINFO_LEN 1024
#define ADDR_LEN 32
//数据包列表信息
struct SPacketListInfo
{
int nNumber;
float fTimeStamp;

char szSurAddr[ADDR_LEN];
char szSurAddrEx[ADDR_LEN];
char szDesAddr[ADDR_LEN];
char szDesAddrEx[ADDR_LEN];

char szAPBSSID[ADDR_LEN];

char szProtocol[ADDR_LEN];
char szInfor[PAKINFO_LEN];

int nFrameSubType;
int nNoise;
int nFCS;
float fRate;
bool bRetry;
};

int __stdcall CreatDecodeObject();
int __stdcall PacketDecode(int nObject,pcap_pkthdr *pkhead,SPacketListInfo* packList,proto_node** protoTree);

//////////这是c++里面的调用 那么我在c#当中该如何调用呢？ 如何传正确的参数
/*c++里面的调用：*/
int nObject = CreatDecodeObject();
pcap_pkthdr hdr;
SPacketListInfo stPakInfo;
proto_node* pNode = NULL;
int nRet = PacketDecode(nObject,&hdr,&stPakInfo,&pNode);

本人不懂c++
请问我在C# 当中如何才能的正确调用 该dll
跪求C# 调用源码 急~~~~~~~

自己顶一个，跪求啊

使用导入dll,网上例子一堆 http://blog.sina.com.cn/s/blog_68c4a1b50100u3kn.html

跟引用API一个样
