抽绳旋转长文本 180

Question

我使用 drawstring 方法在矩形内绘制文本，..我想将文本旋转 180 度，所以我使用了这段代码

   Rectangle displayRectangleh =
       new Rectangle(new Point((int)posh.X, (int)posh.Y), new Size(rectwdh, recth));

   StringFormat format1h = new StringFormat(StringFormatFlags.DirectionVertical);
   format1h.LineAlignment = StringAlignment.Center;
   format1h.Alignment = StringAlignment.Center;
   b = new SolidBrush(Color.Black);
   e.ChartGraphics.Graphics.TranslateTransform((float)rectwdh / 2 + posh.X, recth / 2 + posh.Y);
   e.ChartGraphics.Graphics.RotateTransform(180);
   e.ChartGraphics.Graphics.TranslateTransform(-((float)rectwdh / 2 + posh.X), -(recth / 2 + posh.Y));
            Font boldFonth = new Font(FontFamily.GenericSansSerif, 16, FontStyle.Bold, GraphicsUnit.Pixel, 1, true);
   e.ChartGraphics.Graphics.DrawRectangle(new Pen(Color.Black, 2), displayRectangleh);
   e.ChartGraphics.Graphics.DrawString("This is rotated long text test ", boldFonth, b, (RectangleF)displayRectangleh, format1h);
   e.ChartGraphics.Graphics.ResetTransform();

where posh.X and posh.Y (recatangle position) , rectwdh (rectangle width) and recth (rectangle height)

它非常适合短文本，但对于长文本，新行将在我的旧行上方，请参见下一张图片：

我什至尝试添加换行符 \n 但结果相同。我的问题：如何将文本在矩形内旋转 180 度并最终正确对齐？？

Answer 1

以前从未使用过 StringFormat API，我随机敲打它直到找到这个：

StringFormat format1h = new StringFormat(StringFormatFlags.DirectionVertical | StringFormatFlags.DirectionRightToLeft);
