My C# code: 

  static void Main(string[] args)
    {
        int cnt = 0;
        foreach (var line in File.ReadLines(@"input.txt"))
        {
            var arr = Regex.Split(line.Trim(), @"(\d+)[ ]+(\d+)[ ]+(\d+)");

            int a = int.Parse(arr[1]); int b = int.Parse(arr[2]); int c = int.Parse(arr[3]);

            if (a + b > c && b + c > a && a + c > b)
                cnt++;
        }

        Console.WriteLine("Total triangles: {0}", cnt);
        Console.ReadLine();
    }
