c# - 从 C 转换为 C#，还是制作 DLL？

Question

我是 C# 编程新手。我有一个用 C 语言修改的程序，现在需要获取从 C 程序获得的字符串数组并将其传递给 C# 程序，以便它可以使用这些值查询 Oracle 数据库。

此程序用于从连接到计算机的所有 iButton 设备获取序列号。

这是C代码

// function prototypes
void  UnLoadTMEX(void);
short LoadTMEX(void);

// globals
static FARPROC Get_Version, TMGetTypeVersion, TMEndSession;
static FARPROC TMSetup, TMNext, TMRom, ExtendedStartSession;
static FARPROC TMReadDefaultPort;
long (__fastcall *TMExtendedStartSession)(short,short,void *);

static HINSTANCE hInst;
unsigned char state_buf[5125];

//--------------------------------------------------------------------------
// Main of iSerial64
//
void main(int argc, char **argv)
{
   char refresh,buf[200];
   short flag,i,didsetup=0;
   short ROM[9];
   short PortNum,PortType;
   long SHandle;
   char serialtmp[2], serial[10][17];
   int j = -1;


   // load the TMEX driver and get pointers to functions 
   if (!LoadTMEX())
   {
      printf("ERROR, could not load IBFS64.DLL\n");
      exit(0);
   }

   // load the TMEX driver and get pointers to functions 
   TMReadDefaultPort(&PortNum, &PortType);

   // get the TMEX driver version

   printf("Port number: %d     Port type: %d\n",PortNum,PortType);
   Get_Version(buf);
   printf("Main Driver: %s\n",buf);
   printf("TYPE%d:",PortType);
   if ((short)TMGetTypeVersion(PortType,buf) < 0)
   {
      printf("\nNo Hardware Driver for this type found!\n");
      // Unload the TMEX driver
      UnLoadTMEX();
      exit(0);
   }
   printf(" %s\n\n\n",buf);

   // check the command line
   if (argc > 1)
      PortNum = atoi(argv[1]);

   // check for valid range of PortNum
   if ((PortNum < 1) || (PortNum > 15))
   {
      printf("ERROR, invalid port requested: %d\n",PortNum);
      exit(0);
   }

   // loop to display the rom numbers until key hit
   do
   {
      // get a session handle to the requested port
      SHandle = TMExtendedStartSession(PortNum,PortType,NULL);
      if (SHandle > 0)
      {
         // check to see if TMSetup has been done once
         if (!didsetup)
         {
            flag = (short)TMSetup(SHandle);
            if (flag == 1 || flag == 2)
            {
               printf("TMSetup complete %d\n",flag);
               didsetup = 1;
            }
            else
            {
               printf("ERROR doing setup %d\n",flag);
               break;
            }
         }
         // only get the next rom after setup complete
         else
         {
             //j was added to keep track of the serial number strings
             j++;
             memset(serial[j], 0, strlen(serial[j]));
            flag = (short)TMNext(SHandle,(void far *)&state_buf[0]);
            if (flag > 0)
            {
                ROM[0] = 0;
                flag = (short)TMRom(SHandle, (void far *)&state_buf[0], (short far *)&ROM[0]);
                for (i = 7; i >= 0; i--)
                {
                    //This section was changed from the original
                    //copies raw number into string
                    sprintf(serialtmp, "%02X", ROM[i]);
                    strcat(serial[j], serialtmp);

                }
                printf("%s ", serial[j]);
                printf("\n");

            }
            else
               printf("end of search\n");
         }

         // close the opened session 
         TMEndSession(SHandle);
      }

   } 
   while (flag > 0);

   // Unload the TMEX driver

我应该尝试转换它，还是只是创建一个 C DLL 并将其导入到我的 C# 程序中？就像我说的，我还没有真正使用过 C#，我是一名实习生，我的老板给了我这个项目，以便我可以学习 C#。非常感谢任何帮助

如果你想在 c# 中使用 c dll，请阅读 this文章。 但最好将代码转换为 C# 代码，因为您可以轻松管理此代码并更新代码。
