I want to add shadow on line in different angle of the line

How can i do that ?

What I have tried:

GraphicsPath path = new GraphicsPath();
            path.AddLine(10, 200, 200, 200);
            using (Graphics G = this.CreateGraphics())
                var myPen = new Pen(Color.SkyBlue, 50);
                G.DrawLine(myPen, new Point(10, 200), new Point(200, 200));
                drawShadow(G, Color.Green, path, 25);

void drawShadow(Graphics G, Color c, GraphicsPath GP, int d)
            Color[] colors = getColorVector(c, this.BackColor, d).ToArray();
            for (int i = 0; i < d; i++)
                G.TranslateTransform(0, 1);                // <== shadow vector!
                using (Pen pen = new Pen(colors[i], 1.75f))  // <== pen width (*)
                    G.DrawPath(pen, GP);


        List<Color> getColorVector(Color fc, Color bc, int depth)
            List<Color> cv = new List<Color>();
            float dRed = 1f * (bc.R - fc.R) / depth;
            float dGreen = 1f * (bc.G - fc.G) / depth;
            float dBlue = 1f * (bc.B - fc.B) / depth;
            for (int d = 1; d <= depth; d++)
                cv.Add(Color.FromArgb(255, (int)(fc.R + dRed * d),
                  (int)(fc.G + dGreen * d), (int)(fc.B + dBlue * d)));
            return cv;

What to create shadow according to the argument for line

How big of a shadow are you making here if your doing the TranslateTransform(0, 1) in a for loop? If you need a single shadow, just get the shadow color, and draw the text at an offset, before drawing your main text

The offset could be (x + 1, y + 1) for bottom-right, (x - 1, y + 1) for bottom-left, or (x + i, y + i) if your doing many times though would need to switch the loop to for (int i = d; i > -1; i--){}
