How to get a string width

Question

I need to build a function in a class library that take a string and a specific font for this string then get the width of the string

So how could I get the string boundary width ?

Answer 1

Another way to do this is with a TextRenderer, and call its MeasureString method, passing the string and the font type.

MSDN Example:

private void MeasureText1(PaintEventArgs e)
{
    String text1 = "Measure this text";
    Font arialBold = new Font("Arial", 12.0F);
    Size textSize = TextRenderer.MeasureText(text1, arialBold);
    TextRenderer.DrawText(e.Graphics, text1, arialBold, 
        new Rectangle(new Point(10, 10), textSize), Color.Red);  
}

NOTE: This is just an alternate solution to the (equally valid) one already posted by @Neil Barnwell (in case you already have a reference to System.Windows.Forms in your project, this might be more convenient).
