Example Usage

C# Example

using System.Drawing;
using System.Windows.Forms;

public class MyForm : Form

    {
        this.Paint += new PaintEventHandler(MyForm_Paint);
    }

    private void MyForm_Paint(object sender, PaintEventArgs e)
    {
        Graphics g = e.Graphics;

        // Create a solid blue brush
        using (SolidBrush blueBrush = new SolidBrush(Color.Blue))
        {
            // Draw a filled rectangle

        // Create a solid red brush using a KnownColor
        using (SolidBrush redBrush = new SolidBrush(KnownColor.Red))
        {

        using (SolidBrush greenBrush = new SolidBrush(Color.FromArgb(100, 0, 255, 0))) // Semi-transparent green
        {
            g.DrawString("Hello, SolidBrush!", this.Font, greenBrush, 10, 120);
