how to convert this C function into C-Sharp ?

[Ms. Seren]

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 less than 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;
}

Two code snippets for inspiration:

using System;
using System.IO;
using System.Diagnostics;

namespace E
{
public class Program
{
public static void Main(string[] args)
{
string fnm = @"c:\work\tmp_file";
Process.Start("cmd", "/c ipconfig/all > " + fnm);
using(StreamReader sr = new StreamReader(fnm))
{
string line;
while((line = sr.ReadLine()) != null)
{
Console.WriteLine(line);
}
}
File.Delete(fnm);
Console.ReadKey();
}
}
}

using System;
using System.Net.NetworkInformation;

namespace E
{
public class Program
{
public static void Main(string[] args)
{
foreach(NetworkInterface ni in
NetworkInterface.GetAllNetworkInterfaces())
{
Console.WriteLine("name=" + ni.Name);
foreach(UnicastIPAddressInformation addr in
ni.GetIPProperties().UnicastAddresses)
{
Console.WriteLine("addr=" + addr.Address.ToString());
}
foreach(GatewayIPAddressInformation gw in
ni.GetIPProperties().GatewayAddresses)
{
Console.WriteLine("gw=" + gw.Address.ToString());
}
}
Console.ReadKey();
}
}
}
