Here is a sample:

    /// ---- TextToBitmap ----------------------------
    ///
    /// using System.Drawing;
    /// using System.Drawing.Imaging;
    /// Author: Steve Wellens
    /// 
    /// <summary>
    /// Takes a Text string and returns a bitmap of the string
    /// </summary>

    public static Bitmap TextToBitmap(String TheText)
    {
        Font DrawFont = null;
        SolidBrush DrawBrush = null;
        Graphics DrawGraphics = null;
        Bitmap TextBitmap = null;
        try
        {
            // start with empty bitmap, get it's graphic's object
            // and choose a font
            TextBitmap = new Bitmap(1, 1);
            DrawGraphics = Graphics.FromImage(TextBitmap);
            DrawFont = new Font("Arial", 16);

            // see how big the text will be
            int Width = (int)DrawGraphics.MeasureString(TheText, DrawFont).Width;
            int Height = (int)DrawGraphics.MeasureString(TheText, DrawFont).Height;

            // recreate the bitmap and graphic object with the new size
            TextBitmap = new Bitmap(TextBitmap, Width, Height);
            DrawGraphics = Graphics.FromImage(TextBitmap);

            // get the drawing brush and where we're going to draw
            DrawBrush = new SolidBrush(Color.Black);
            PointF DrawPoint = new PointF(0, 0);

            // clear the graphic white and draw the string
            DrawGraphics.Clear(Color.White);
            DrawGraphics.DrawString(TheText, DrawFont, DrawBrush, DrawPoint);

            return TextBitmap;
        }
        finally
        {
            // don't dispose the bitmap, the caller needs it.
            DrawFont.Dispose();
            DrawBrush.Dispose();
            DrawGraphics.Dispose();
        }
    }
