How To Use Settings File

First thing we need to do is adding a windows form from project.
Our windows form must be Settings File.

Into Settings File we are writing like this :

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Setting_Kullanma
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
this.Text = Ayarlar.Default.FormIsmi;
this.BackColor = Ayarlar.Default.FormArkaPlan;
}
}
}
