how to convert this C function into C # code?

[serendipity1276]

Hi,

Can any C-Sharp expert out there convert the C function below, into
C-Sharp code, that I can insert into an already-existing C-Sharp program, that will compile? Thanks.

I have an existing C code that compiles in the C environment. I want to insert this function into an already running C-Sharp program. Because I only have a week to get this done, learning C-Sharp at this time is not practical.

The C function is simple:

a) get the output of the ipconfig /all command, write it into a tmp file
b) read that file for the string "gateway.net" or for anything string
that contains the string "192.168.1"
c) if this is found, set found = 1
d) when done, delete the tmp file
e) if found == 0, stop the program

Below is that C function.

Check ( )

{
  char str [100];
  int found = 0;

  FILE *fi;

  system ("ipconfig /all > c:\\temp\\tmp_file");

  fi = fopen ("c:\\temp\\tmp_file", "r");
  
  while (! feof (fi))
    {
      fscanf (fi, "%s", str);

      if ((strcmp (str, "gateway.net") == 0) || (strstr (str, "192.168.1") != NULL))
        found = 1;
    }

  fclose (fi);
  
  remove ("c:\\temp\\tmp_file");

  if (found == 0)
    exit (0);

  return 0;
}

Why would you want to convert something which is full of bugs?

> system ("ipconfig /all > c:\\temp\\tmp_file");
Chances are, c# already has a method to enumerate all the network connections anyway.

You don't have to learn it all, just enough to make a reasonable stab at it.
1 day on C# network APIs might go a long way to helping you solve the problem.

Salam is right, there are some nice helpers built into C# for this kind of thing. Hint: use the System.Net.NetworkInformation namespace.

I've just put together a C# version of what you require in a few lines of code, without the need to dump the contents of ipconfig into a file.

Have a go, now that you know which namespace you need. I can post my code if you want, but it would be better to learn yourself. It's actually quite simple.

How do you get stuck with a job that you're unqualified for? I'm guessing this is for work. Undoubtedly, you'd just steal our code and pass it off as your own.
