100分C#调用C++动态库

[zhengjob]

C++的库如下：
#define SOCKET_PACKHEAD_LENGTH 92
#define SOCKET_PACKCHECK_LENGTH 96

#define SOCKET_LENGTH_LENGTH 5
#define SOCKET_LENGTH_POS 0
#define SOCKET_CATEGORY_LENGTH 2
#define SOCKET_CATEGORY_POS 5
#define SOCKET_SUB_COMMAND_LENGTH 2
#define SOCKET_SUB_COMMAND_POS 7
#define SOCKET_OPCODE_LENGTH 4
#define SOCKET_OPCODE_POS 9
#define SOCKET_SEQNO_LENGTH 10
#define SOCKET_SEQNO_POS 13
#define SOCKET_SPID_LENGTH 4
#define SOCKET_SPID_POS 23
#define SOCKET_SERVERID_LENGTH 5
#define SOCKET_SERVERID_POS 27
#define SOCKET_OPERATEID_LENGTH 5
#define SOCKET_OPERATEID_POS 32
#define SOCKET_CALLINGNUMBER_LENGTH 20
#define SOCKET_CALLINGNUMBER_POS 37
#define SOCKET_CALLEDNUMBER_LENGTH 20
#define SOCKET_CALLEDNUMBER_POS 57
#define SOCKET_ERROR_LENGTH 5
#define SOCKET_ERROR_POS 77
#define SOCKET_CRY_TYPE_LENGTH 5
#define SOCKET_CRY_TYPE_POS 82
#define SOCKET_KEY_NO_LENGTH 5
#define SOCKET_KEY_NO_POS 87

struct PACKET_HEAD //包头数据结构
{
unsigned int PACKETLENGTH;
unsigned char CATEGORY[SOCKET_CATEGORY_LENGTH+1];
unsigned char SUBCOMMAND[SOCKET_SUB_COMMAND_LENGTH+1];
unsigned char OPCODE[SOCKET_OPCODE_LENGTH+1];
unsigned char SEQNO[SOCKET_SEQNO_LENGTH+1];
unsigned char SPID[SOCKET_SPID_LENGTH+1];
unsigned char SERVERID[SOCKET_SERVERID_LENGTH+1];
unsigned char OPERATEID[SOCKET_OPERATEID_LENGTH+1];
unsigned char CALLINGNUMBER[SOCKET_CALLINGNUMBER_LENGTH+1];
unsigned char CALLEDNUMBER[SOCKET_CALLEDNUMBER_LENGTH+1];
unsigned char RESULT[SOCKET_ERROR_LENGTH+1];
unsigned char CRYTYPE[SOCKET_CRY_TYPE_LENGTH+1];
unsigned char KEYNO[SOCKET_KEY_NO_LENGTH+1];
};

typedef struct PACKET_HEAD * Packet_Head;

unsigned int VSPPCommInit(unsigned int nPort,unsigned int key);
unsigned int VSPPReceiveAccept(unsigned char * IP,unsigned int &Port);
unsigned int VSPPCheckConnectStatus(unsigned char *IP,unsigned int Port);
unsigned int VSPPSendMessage(unsigned

char

*IP,unsigned int Port,
PACKET_HEAD pPackethead,char * sPackbody);
unsigned int VSPPReceiveMessage(unsigned char * IP,unsigned int &Port,
PACKET_HEAD &pPackethead,char * sPackbody);
unsigned int VSPPCloseConnect(unsigned char *IP,unsigned int Port);
void VSPPReleaseSource();


求把上面的代码转为C#调用

已推荐………………

这有什么好推荐的？

[十八道胡同]

用C#来调用C++的dll [DllImport...]

[fontain2]

1.简单的包装问题，没必要推荐 2.C++打包成动态链接库，由C#导入就可以，标准做法，难不成你还想直接编译进C#?

[雪狼隐迹X]

这个没看懂，抱歉哟

[dinghaohong81]

1、你在C++环境把C++代码打包成dll 2、然后再C#里调用：（先把dll放入bin文件夹中；然后.aspx.cs文件中调用） 、、、、、、、、、、、、、、、、、、、 例如：try.dll 可以在文件中声明为全局变量， try.Class aaa= new try.Class(); protected void Page_Load(object sender, EventArgs e) { ViewState["fldm"] = aaa.函数名(); }

学习学习，回去试试

[comcyd]

百度应该能找到一大片吧

[shuiyuan622]

先把C++代码打包成dll 1 将dll 放置到c#工程的bin/debug目录下 2 在c#工程中加入函数声明，如下 c++ 函数: HANDLE __stdcall IC_InitComm(__int16 port); C#中的声明： [DllImport("dcic32.dll")] public static extern IntPtr IC_InitComm(Int16 port); 3 调用： IntPtr handle = IC_InitComm(100);

做一个clr的C++动态链接库做中转，C# 导入clr 动态链接库

使用com接口

[IE11下面经常卡到爆]

const int SOCKET_SUB_COMMAND_LENGTH = xxx; public struct PACKET_HEAD { public uint PACKETLENGTH; [MarshalAs(UnmanagedType.ByValArray, SizeConst=SOCKET_SUB_COMMAND_LENGTH + 1)] public byte[] CATEGORY; 其他字段类似 }

我最近就在纠结到底是怎么编译进去的，我有一个.Net的dll但里面有C++的“成分”这里让发网盘链接么

[IE11下面经常卡到爆]

你说的那是C++.Net，还是基于.Net的，只不过大部分用的C++的语法
