Fill shapes with gradient brush

Closed shapes(rectangles, ellipses,...) that are drawn on the control can be filled with a mix of colors by using LinearGradientBlush object. You can create a LinearGradientBrush object from the LearnGradientBrush class of System.Drawing.Drawing2D library.

Example: filling the rectangle and ellipse with a mix of colors

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Drawing.Drawing2D;

using System.Linq;

using System.Text;

using System.Windows.Forms;


namespace WindowsFormsApplication2


    public partial class Form2 : Form


        public Form2()





        private void Form2_Load(object sender, EventArgs e)


            this.WindowState = FormWindowState.Maximized;




        private void Form2_Paint(object sender, PaintEventArgs e)



            //Create graphic object for the current form

            Graphics gs = this.CreateGraphics();

            //Create a rectangle object

            Rectangle rt = new Rectangle(20, 100, 200, 200);

            Rectangle rt1 = new Rectangle(230, 100, 200, 200);


            //Create brush object

            LinearGradientBrush lb = new LinearGradientBrush(



                Color.FromArgb(255, 0, 0, 0),


            LinearGradientBrush lb1 = new LinearGradientBrush(


                Color.FromArgb(255, 0, 255, 0),

                Color.FromArgb(255, 0, 0, 255),


            //fill the shapes

            gs.FillRectangle(lb, rt);

            gs.FillEllipse(lb1, rt1);
