C# と VB.NET の質問掲示板

> ・特定のフォルダーに XML で保存するのか

XMLに保存したいです。

CustomColors プロパティとは　public int[] CustomColors { get; set; }　の事ですよね？

>CustomColorsは追加した色がint配列で格納されているので
>ダイアログを閉じたときにCustomColorsを参照して適当なファイルに保存

どう参照すればいいのでしょう？

素人なので本当にわからないのですごく困ってます。

namespace ApplicationTest001
{
    public partial class Form1 : Form
    {
        private int Form1BackColor;

        //public int[] CustomColors { get; set; }


        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            if (colorDialog1.ShowDialog() == DialogResult.OK)
            {
                Form1BackColor = colorDialog1.Color.ToArgb();
                BackColor = colorDialog1.Color; 
            }
        }

        
        private void Form1_Load(object sender, EventArgs e)
        {
            textBox1.Text = Properties.Settings.Default.textBox1;
            Form1BackColor = Properties.Settings.Default.Form1BackColor;
        }

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            Properties.Settings.Default.textBox1 = this.textBox1.Text;
            Properties.Settings.Default.Save();
        }
    }
}

コレで上手くいかないのはなんででしょう？

private void LoadCustomColors(ColorDialog targetColorDialog)
private void SaveCustomColors(ColorDialog sourceColorDialog)

↑ココの呼び出し方読み込み方がわからない。

namespace ApplicationTest001
{

    public partial class Form1 : Form
    {
        
        private int Form1BackColor;

        public Form1()
        {
            InitializeComponent();
        }

        

        private void button1_Click(object sender, EventArgs e)
        {
            if (colorDialog1.ShowDialog() == DialogResult.OK)
            {
                Form1BackColor = colorDialog1.Color.ToArgb();
                BackColor = colorDialog1.Color;
                
            }
            
        }

        private void LoadCustomColors(ColorDialog targetColorDialog)
        {
            targetColorDialog.CustomColors =
                Properties.Settings.Default.ColorSettings.Split(new[] { ',' }, 16).Select(int.Parse).ToArray();
        }

        private void SaveCustomColors(ColorDialog sourceColorDialog)
        {
            Properties.Settings.Default.ColorSettings = string.Join(",", sourceColorDialog.CustomColors);
            Properties.Settings.Default.Save();
        }



        private void Form1_Load(object sender, EventArgs e)
        {
            textBox1.Text = Properties.Settings.Default.textBox1;
            Form1BackColor = Properties.Settings.Default.Form1BackColor;
        }

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            Properties.Settings.Default.textBox1 = this.textBox1.Text;
            Properties.Settings.Default.Save();
        }

        
    }
}

一応、出来たっぽいです。。。。
これであってますかね？

namespace ApplicationTest001
{

    public partial class Form1 : Form
    {
        
        private int Form1BackColor;
        

        public Form1()
        {
            InitializeComponent();
        }

        
        private void button1_Click(object sender, EventArgs e)
        {
            if (colorDialog1.ShowDialog() == DialogResult.OK)
            {
                Form1BackColor = colorDialog1.Color.ToArgb();
                BackColor = colorDialog1.Color;
            }
            
        }

        
        private void Form1_Load(object sender, EventArgs e)
        {
            textBox1.Text = Properties.Settings.Default.textBox1;
            Form1BackColor = Properties.Settings.Default.Form1BackColor;
            ColorSave();
        }

        private void ColorSave()
        {
            colorDialog1.CustomColors = Properties.Settings.Default.ColorSettings.Split(new[] { ',' }, 16).Select(int.Parse).ToArray();
        }

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            Properties.Settings.Default.textBox1 = this.textBox1.Text;
            Properties.Settings.Default.ColorSettings = string.Join(",", colorDialog1.CustomColors);
            Properties.Settings.Default.Save();
        }
    }
}

見た目的にこうかな？

namespace ApplicationTest001
{

    public partial class Form1 : Form
    {
        
        private int Form1BackColor;
        

        public Form1()
        {
            InitializeComponent();
        }

        
        private void button1_Click(object sender, EventArgs e)
        {
            if (colorDialog1.ShowDialog() == DialogResult.OK)
            {
                Form1BackColor = colorDialog1.Color.ToArgb();
                BackColor = colorDialog1.Color;
            }
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            textBox1.Text = Properties.Settings.Default.textBox1;
            Form1BackColor = Properties.Settings.Default.Form1BackColor;
            CustomColorLoad();
        }

        private void CustomColorLoad()
        {
            colorDialog1.CustomColors = Properties.Settings.Default.ColorSettings.Split(new[] { ',' }, 16).Select(int.Parse).ToArray();
        }

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            Properties.Settings.Default.textBox1 = this.textBox1.Text;
            CustomColorSave();
            Properties.Settings.Default.Save();
        }

        private void CustomColorSave()
        {
            Properties.Settings.Default.ColorSettings = string.Join(",", colorDialog1.CustomColors);
        }
    }
}
