C#调色板如何显示颜色
用C#的什么控件能够显示颜色？我在做一个调色板程序，但是只能改变字体颜色，却无法改变某一控件的颜色或者在某一区域显示调出的颜色。
以下是代码，请指教


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 _1113640111秦超
{
public partial class Form1 : Form
{
int r, g, b;
public Form1()
{
InitializeComponent();
}

private void hScrollBar1_Scroll(object sender, ScrollEventArgs e)
{
textBox1.Text = (hScrollBar1.Value).ToString();
listBox1 .BackColor = System.Drawing.Color.FromArgb(r = hScrollBar1.Value);
}

private void hScrollBar2_Scroll(object sender, ScrollEventArgs e)
{
textBox2.Text = (hScrollBar2.Value).ToString();
listBox1.BackColor = System.Drawing.Color.FromArgb(g = hScrollBar2.Value);
}

private void hScrollBar3_Scroll(object sender, ScrollEventArgs e)
{
textBox3.Text = (hScrollBar3.Value).ToString();
listBox1.BackColor = System.Drawing.Color.FromArgb(b = hScrollBar3.Value);
}
}
}

C#调用调色板

C# code

            ColorDialog colorDialog1 = new ColorDialog();            colorDialog1.FullOpen = true; //是否显示ColorDialog有半部分            //colorDialog1.CustomColors = colorDialog1.Color;//设置自定义颜色            DialogResult result = colorDialog1.ShowDialog();            if (result == DialogResult.OK)//确定事件响应            {                Color color_from = colorDialog1.Color;                int a = color_from.R;                int b = color_from.G;                int c = color_from.B;                string str;                str=a.ToString()+"  "+b.ToString()+"  "+c.ToString()+"  ";                MessageBox.Show(str);            }

如果我想把颜色值转成Int类型的应该怎么办呢。
