keywords: stretch text, Graphics, DrawString, GraphicsPath, draw text, draw string, text, text size, C#.NET

It helps to draw a text completely streched to your frame. it Works with the help of Graphics Objects Measuring String

You have to import a namespace.
using System.Drawing.Drawing2D;

The System.Drawing.Drawing2D namespace provides advanced two-dimensional and vector graphics functionality.

Here the complete code.

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;
using System.Drawing.Drawing2D;

namespace testc

    public partial class Form1 : Form
        public Form1()
        private void Form1_Load(object sender, EventArgs e)

        private void Form1_Paint(object sender, PaintEventArgs e)
            // Get the target area.

                Rectangle target = new Rectangle(8, 8, this.ClientSize.Width - 16,
                    this.ClientSize.Height - 16);

                Font the_font = new Font("Times New Roman", target.Height,
                    FontStyle.Bold, GraphicsUnit.Pixel);

                // Make the StringFormat.
                StringFormat sf = new StringFormat();
                sf.Alignment = StringAlignment.Center;
                sf.LineAlignment = StringAlignment.Center;

                // Add the text to the GraphicsPath.
                GraphicsPath text_path = new GraphicsPath();
                text_path.AddString("Hello .NET World", the_font.FontFamily,
                    Convert.ToInt32(FontStyle.Bold), target.Height, new PointF(0, 0), sf);

                RectangleF text_rectf = text_path.GetBounds();
                PointF[] target_pts = {
            new PointF(target.Left, target.Top),
            new PointF(target.Right, target.Top),
            new PointF(target.Left, target.Bottom)};
                e.Graphics.Transform = new Matrix(text_rectf, target_pts);

                // Draw the text.
                e.Graphics.SmoothingMode = SmoothingMode.AntiAlias;
                e.Graphics.FillPath(Brushes.Blue, text_path);
                e.Graphics.DrawPath(Pens.Blue, text_path);


                //It draws the boundry for the text.
                e.Graphics.DrawRectangle(Pens.Red, target);

                // to clear the graphics.
