Right-Aligning printed text

Use the Graphics.MeasureString Method to get how long the rendered string will be and draw it at rightMargin - measuredStringWidth.

In order for it to be able to right align the text, you need to specify a layout rectangle:

var format = new StringFormat() { Alignment = StringAlignment.Far };
var rect = new RectangleF( x, y, width, height );

e.Graphics.DrawString( text, font, brush, rect, format );

And it will then align the string within that rectangle.
