Mit dieser Klasse kann sehr einfach lesend und schreibend auf INI – Dateien zugegriffen werden.
public class IniFile
  {
    public string path;

    [DllImport("kernel32")]
    private static extern long WritePrivateProfileString(string section,
      string key,string val,string filePath);

    [DllImport("kernel32")]
    private static extern int GetPrivateProfileString(string section,
      string key,string def, StringBuilder retVal,
      int size,string filePath);
   
    public IniFile(string INIPath)
    {
      path = INIPath;
    }
    
    public void IniWriteValue(string Section,string Key,string Value)
    {
      WritePrivateProfileString(Section,Key,Value,this.path);
    }
   
    public string IniReadValue(string Section,string Key)
    {
      StringBuilder temp = new StringBuilder(255);
      int i = GetPrivateProfileString(Section,Key,"",temp,255, this.path);
      return temp.ToString();
    }
