How to programmatically measure string pixel width in ASP.NET?

Question

How do you get the size of a string? In Windows Forms it\'s easy, I just use graphics object and then MeasureString function. In ASP.NET I\'m not sure how to do this.

Answer 1

The following method will provide the size of a String rendered in a given font:

private RectangleF sizeOfString(string text, Font font)
{
    GraphicsPath path = new GraphicsPath();
    path.AddString(text, font.FontFamily, (int)font.Style, font.Size, new Point(0, 0), new StringFormat());
    return path.GetBounds();
}

You could then use this to get the width as follows

float width = sizeOfString("Hello World", someFont).Width;
