====== Read from text file ======
  * Here is the code for reading from text file.
<code csharp>

            StreamReader sr = null;
            string file = @"c:\temp\test.txt";
            string line;

            try
            {
                sr = new StreamReader(file);
                while ((line = sr.ReadLine()) != null)
                {
                    Console.WriteLine(line);
                }
            }
            finally
            {
                if (sr!= null) sr.Dispose();
            }

<code csharp>
            string file = @"c:\temp\test.txt";
            using (StreamReader sr = File.OpenText(file))
            {
                    string line;
                    while ((line = sr.ReadLine()) != null)
                    {
                        Console.WriteLine(line);
                    }
            }

  * If you need to read types, like in fscanf, you can use the code above, or write scanf yourself :-)
<code csharp>
           String[] values = line.Split(' ');
           int id = int.Parse(values[0]);
           ...
