How to use C # To display vertical lines of text?

Looking at this question, I think it is not difficult. I thought it was the same at the beginning, but currently I have no reference on my hand to introduce vertical text display, only one useful information is found on the Internet, but it is difficult to achieve it. It requires coordinate conversion, rotation, and translation. No way. In order to mark the Y-direction coordinates, we have to do this, the Code is as follows:

// Set the center of rotation
Pb_graphics.translatetransform (panelruley. width/2, panelruley. Height/2 );
// Set the Rotation Angle
Pb_graphics.rotatetransform (90 );
// Translation
Pb_graphics.translatetransform (I-19-panelruley. Height/2 + 22-(20-panelwork.top),-3 );
// Draw text
Pb_graphics.drawstring (INT) (I-19). tostring (), Font, new solidbrush (color. Black), 0, 0 );
// Restore to the default scenario
Pb_graphics.resettransform ();

It may have ended like this. However, today I walked around in the bookstore and saw a more direct way to implement vertical lines of text, so I quickly bought the book, the method of returning home implements vertical lines of text. The latest code is as follows (only one sentence of code ):

Pb_graphics.drawstring (INT) (I-19 )). tostring (), Font, new solidbrush (color. black),-2, I-(20-panelwork. top) + 2, new stringformat (stringformatflags. directionvertical ));

Note:: The streamlined framework set is not supported. I tried this code under the streamlined framework set, so I did not find this method!
