Introduction

I created a C# class Ini which exposes 2 functions from KERNEL32.dll. These functions are: WritePrivateProfileString and GetPrivateProfileString

Namespaces you will need: System.Runtime.InteropServices and System.Text

The Class

Collapse

using System;
using System.Runtime.InteropServices;
using System.Text;

namespace Ini
{
    /// <summary>

    /// Create a New INI file to store or load data

    /// </summary>

    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);

        /// <summary>

        /// INIFile Constructor.

        /// </summary>

        /// <PARAM name="INIPath"></PARAM>

        public IniFile(string INIPath)
        {
            path = INIPath;
        }
        /// <summary>

        /// Write Data to the INI File

        /// </summary>

        /// <PARAM name="Section"></PARAM>

        /// Section name

        /// <PARAM name="Key"></PARAM>

        /// Key Name

        /// <PARAM name="Value"></PARAM>

        /// Value Name

        public void IniWriteValue(string Section,string Key,string Value)
        {
            WritePrivateProfileString(Section,Key,Value,this.path);
        }
        
        /// <summary>

        /// Read Data Value From the Ini File

        /// </summary>

        /// <PARAM name="Section"></PARAM>

        /// <PARAM name="Key"></PARAM>

        /// <PARAM name="Path"></PARAM>

        /// <returns></returns>

        public string IniReadValue(string Section,string Key)
        {
            StringBuilder temp = new StringBuilder(255);
            int i = GetPrivateProfileString(Section,Key,"",temp, 
                                            255, this.path);
            return temp.ToString();

        }
    }
}

Using the class

Steps to use the Ini class:

1. In your project namespace definition add 
   Collapse

   using INI;

2. Create a INIFile like this
   
   Collapse

   INIFile ini = new INIFile("C:\\test.ini");

3. Use IniWriteValue to write a new value to a specific key in a section or use IniReadValue to read a value FROM a key in a specific Section.

That's all. It's very easy in C# to include API functions in your class(es).
