c#PictureBox控件旋转图片

使用Bitmap中的RotateFlip()方法

//旋转图片private void pictureBox_Probe_Click(object sender, EventArgs e){Bitmap b = new Bitmap(pictureBox_Probe.Image);b.RotateFlip(RotateFlipType.Rotate90FlipXY);//旋转90度//b.RotateFlip(RotateFlipType.Rotate90FlipNone);//不进行翻转的旋转pictureBox_Probe.Image = b;}
