Hi this is small class I made to learn about files and strings in C#, it read a text file with keys and valules you chould use this to make your program support language files. anyway hope this may help someone

Class Code

Code:
using System;
using System.Collections;
using System.Linq;
using System.Text;
using System.IO;
namespace StrList
{
    public class cStrList
    {
       // string File;
        Hashtable ht = new Hashtable();

        //Consturctor
        public cStrList(string Filename)
        {
            //Filename to open
            string sLine = "";
            string sKey = "";
            string sValue = "";
            int s_pos = 0;
            //File = Filename;
            
            //Create file stream object
            StreamReader sr = new StreamReader(Filename);

            while (sLine !=null)
            {
                //Read the line
                sLine = sr.ReadLine();

                if (sLine != null)
                {
                    if (Convert.ToBoolean(sLine.Length))
                    {
                        s_pos = sLine.IndexOf("=");
                        if (s_pos > -1)
                        {
                            //Extract Key.
                            sKey = sLine.Substring(0, s_pos).Trim();
                            //Extract Value.
                            sValue = sLine.Substring(s_pos + 1, sLine.Length - s_pos - 1).Trim();
                            //Test if key is already added
                            if (!ht.ContainsKey(sKey))
                            {
                                //Store the key and value into hashtable.
                                ht.Add(sKey, sValue);
                            }
                        }
                    }
                }
            }
            sr.Close();
        } 

        public string ReadValue(int Key)
        {
            //This returns a string from a given key.
            try
            {
                //Try and resturn value
                return ht[Key.ToString()].ToString();
            }
            catch
            {
                //Just return
                return "";
            }
        }

    }
}
Example code

Code:
        private void button1_Click(object sender, EventArgs e)
        {
            //Example File
            //100=String List Example
            //101=About
            //102=E&xit

            //Code example
            string Filename;
            Filename = "C:\\cd\\test.txt";

            if (!System.IO.File.Exists(Filename))
            {
                MessageBox.Show("File Not Found\n" + Filename,"File Not Found",
                    MessageBoxButtons.OK,MessageBoxIcon.Error);
            }
            else
            {
                cStrList cLst = new cStrList(Filename);
                //Set form text properties
                ActiveForm.Text = cLst.ReadValue(100);
                cmdAbout.Text = cLst.ReadValue(101);
                cmdExit.Text = cLst.ReadValue(102);
            }
        }
