I want to write a vertical text in my graphic instances using DrawString.

My code is like this :

var graph = Graphics.FromImage(map);

And I read the text and their position from Database :

graph.DrawString(ObjStationRepository.FindBy(i => i.Id == t.StationId).First().Description, new Font("B Nazanin", 18), Brushes.White, t.XLocation + 70, t.YLocation +80);

But my problem is ,i need to write the text in vertical position not horizontal .But DrawString write the text in horizontal !!

Use

System.Drawing.StringFormat drawFormat = new System.Drawing.StringFormat();
drawFormat.FormatFlags = StringFormatFlags.DirectionVertical;

and add it as the last param to DrawString
