You can use the RotateTransform and TranslateTransform that are available on the Graphics class. Because using DrawString is GDI+ the transforms affects the drawing. So use something like this...

g.RotateTransform(45f);
g.DrawString("My String"...);
g.RotateTransform(-45f);

Don't forget to reverse the change though!

Do a Graphics.rotateTransform before the drawString call. Don't forget to reverse the change afterwards, as Phil Wright points out.

You can have lotsa fun adding a semi-random transform for every line in a text editor :) – leppie Sep 18 '08 at 10:43

You can use this function.

   void DrawDigonalString(Graphics G, string S, Font F, Brush B, PointF P, int Angle)
   {
       SizeF MySize = G.MeasureString(S, F);
       G.TranslateTransform(P.X + MySize.Width / 2, P.Y + MySize.Height / 2);
       G.RotateTransform(Angle);
       G.DrawString(S, F, B, new PointF(-MySize.Width / 2, -MySize.Height / 2));
       G.RotateTransform(-Angle);
       G.TranslateTransform(-P.X - MySize.Width / 2, -P.Y- MySize.Height / 2);
   }

Like this

Works like a charm! But how can I determine the width of the angled text? e.g. if I have a string width of 50. After rotating the text, it'll take less width... – prototype0815 Jan 05 '18 at 07:19

There is another way to draw a text vertically which is built in the C#. There is no need of explicit graphics transformation. You can use the StringFormat class. Here is a sample code which draws a text vertically:

StringFormat sf = new StringFormat(); sf.FormatFlags = StringFormatFlags.DirectionVertical; e.Graphics.DrawString("My String", this.Font, Brushes.Black, PointF.Empty, sf);
