[筆記]How to get string width by different font style

Try to use this method :

Graphics.MeasureString(String, Font)

Example :

private void MeasureStringMin(PaintEventArgs e)
{
    // Set up string.
    string measureString = "Measure String";
    Font stringFont = new Font("Arial", 16);

    // Measure string.
    SizeF stringSize = new SizeF();
    stringSize = e.Graphics.MeasureString(measureString, stringFont);

    // Draw rectangle representing size of string.
    e.Graphics.DrawRectangle(new Pen(Color.Red, 1), 0.0F, 0.0F, stringSize.Width, stringSize.Height);

    // Draw string to screen.
    e.Graphics.DrawString(measureString, stringFont, Brushes.Black, new PointF(0, 0));
}

this is also useful in game :)

        return cp;
    }
}
