绘制多行文本需要计算行高，然后绘出字符串：
1
private
void
Form1_Paint(
object
sender, PaintEventArgs e)
2 {
3 Graphics g = e.Graphics;
4 g.FillRectangle(Brushes.White, this .ClientRectangle);
5 string s = " This string is long enough to wrap. " ;
6 s += " With a 200px-width rectangle,and a 12pt font. " ;
7 s += " it requires six lines to display the stirng in its entirety. " ;
8
9 Font f = new Font( " Arial " , 12 );
10 Rectangle r = new Rectangle( 20 , 20 , 200 , f.Height * 6 );
11 g.DrawRectangle(Pens.Black,r);
12 g.DrawString(s, f, Brushes.Black, r);
13
14 f.Dispose();
15 }
2 {
3 Graphics g = e.Graphics;
4 g.FillRectangle(Brushes.White, this .ClientRectangle);
5 string s = " This string is long enough to wrap. " ;
6 s += " With a 200px-width rectangle,and a 12pt font. " ;
7 s += " it requires six lines to display the stirng in its entirety. " ;
8
9 Font f = new Font( " Arial " , 12 );
10 Rectangle r = new Rectangle( 20 , 20 , 200 , f.Height * 6 );
11 g.DrawRectangle(Pens.Black,r);
12 g.DrawString(s, f, Brushes.Black, r);
13
14 f.Dispose();
15 }
绘制竖向文本，需要指定StringFormat类为DirectionVertical，即：StringFormat sf = new StringFormat(StringFormatFlags.DirectionVertical);
然后应用于文字
SizeF sizef = g.MeasureString(s, f, Int32.MaxValue, sf);
// Create and draw the rectangle
// Also draw the text string (using the StringFormat object)
RectangleF rf = new RectangleF(20, 20, sizef.Width, sizef.Height);
代码如下：
1
private
void
Form1_Paint(
object
sender,
2 System.Windows.Forms.PaintEventArgs e)
3 {
4 Graphics g = e.Graphics;
5 g.FillRectangle(Brushes.White, this .ClientRectangle);
6
7 // Create a text string, a Font object, and a StringFormat object
8 String s = " Accrington Stanley " ;
9 StringFormat sf = new StringFormat(StringFormatFlags.DirectionVertical);
10 Font f = new Font( " Times New Roman " , 14 );
11
12 // Calculate the size of the text string's containing rectangle
13 SizeF sizef = g.MeasureString(s, f, Int32.MaxValue, sf);
14
15 // Create and draw the rectangle
16 // Also draw the text string (using the StringFormat object)
17 RectangleF rf = new RectangleF( 20 , 20 , sizef.Width, sizef.Height);
18 g.DrawRectangle(Pens.Black, rf.Left, rf.Top, rf.Width, rf.Height);
19 g.DrawString(s, f, Brushes.Black, rf, sf);
20
21 f.Dispose();
22 }
2 System.Windows.Forms.PaintEventArgs e)
3 {
4 Graphics g = e.Graphics;
5 g.FillRectangle(Brushes.White, this .ClientRectangle);
6
7 // Create a text string, a Font object, and a StringFormat object
8 String s = " Accrington Stanley " ;
9 StringFormat sf = new StringFormat(StringFormatFlags.DirectionVertical);
10 Font f = new Font( " Times New Roman " , 14 );
11
12 // Calculate the size of the text string's containing rectangle
13 SizeF sizef = g.MeasureString(s, f, Int32.MaxValue, sf);
14
15 // Create and draw the rectangle
16 // Also draw the text string (using the StringFormat object)
17 RectangleF rf = new RectangleF( 20 , 20 , sizef.Width, sizef.Height);
18 g.DrawRectangle(Pens.Black, rf.Left, rf.Top, rf.Width, rf.Height);
19 g.DrawString(s, f, Brushes.Black, rf, sf);
20
21 f.Dispose();
22 }
