Read and write INI files in C #

There are no classes in C # that read and write INI files, but they are easy to implement with API functions.

The form code is as follows:

Using System;
Using System.Collections.Generic;
Using System.ComponentModel;
Using System.Data;
Using System.Drawing;
Using System.Text;
Using System.Windows.Forms;
Using System.Runtime.InteropServices;

Namespace Inifiledemo
{
public partial class Form1:form
{
/**//**//**////<summary>
Read INI file API function declaration
</summary>
<param name= "section" > subsection name </param>
<param name= "key" > Keyword </param>
<param name= "def" > Default value if not found </param>
<param name= "RetVal" > buffer to store return values </param>
<param name= "Size" > Buffer size </param>
<param name= "FilePath" > Path to the INI file to read </param>
<returns> returns the number of characters read to </returns>
[DllImport ("kernel32")]
        private static extern long GetPrivateProfileString (string section, string Key, String def, StringBuilder retVal, int size, string filePath);

       /**//**//**////<summary>
        ///Write INI file API function declaration
       ///</ Summary>
       ///<param name= "section" > subsection name </param>
       ///<param name= "key" > Keywords </param>
        ///<param name= "val" > The value to be written </param>

       / <returns> returns the number of characters written </returns>
        [DllImport ("kernel32")]
        private static extern long WritePrivateProfileString (string section, String key, String val, string filePath);

Public Form1 ()
{

}
