Here is a class for reading & writing INI file from/to Micro SD
It is very simple one... but does the work just fine ;-)
Any feedback will be nice to have.

Here is the source code:


using System;
using System.IO;
using System.Collections;
using System.Threading;

namespace NetduinoPlusMonitor
{
  public class CIni
  {
    public CIni()
    {
      _Sections = new Hashtable();
    }

    /// <summary>
    /// Loads the Reads the data in the ini file into the IniFile object
    /// </summary>
    /// <param name="filename"></param>
    public void Load(string FileName, bool append)
    {
      if (!append)
        DeleteSections();

      string Section = "";
      string[] keyvaluepair;

      using (FileStream inFileStream = new FileStream(Path.Combine("\\SD",FileName), FileMode.Open))
      {
        using (StreamReader inStreamReader = new StreamReader(inFileStream))
        {
          string[] lines = inStreamReader.ReadToEnd().ToLower().Split(new char[] { '\n', '\r' });

          foreach(string line in lines)
          {
            if (line == string.Empty)
              continue;
            if (';' == line[0])
              continue;

            if ('[' == line[0] && ']' == line[line.Length - 1])
              Section = line.Substring(1, line.Length - 2);

            else if (-1 != line.IndexOf("="))

Thank You..

I was just looking for some of my old code in order to use an ini file.. I will not bother looking further..

Strange.. I was looking for my old code and by chance.. I need to look no further... Yours looks to be more compact than what I remember of mine.

im new using the netduino and i will appreciate if you could show an example of the use of this class on the main program.

 

and thank you so much :P for this post
