也可以是这样的:

就像在 CAD 软件中一样.

推荐答案

这是我使用的代码.x 和 y 是维度.就我而言，我可以在光标上放置一些文本，这就是名称.如果你想要点或破折号，那么你需要用笔来做.

This is the code I use. x and y are the dimensions. In my case I can have some text on the cursor and this is name. If you want dots or dashes then you need to do that with the pen.

   private Cursor crossCursor(Pen pen, Brush brush, string name, int x, int y) {
            var pic = new Bitmap(x, y);
            Graphics gr = Graphics.FromImage(pic);

            var pathX = new GraphicsPath();
            var pathY = new GraphicsPath();
            pathX.AddLine(0, y / 2, x, y / 2);
            pathY.AddLine(x / 2, 0, x / 2, y);
            gr.DrawPath(pen, pathX);
            gr.DrawPath(pen, pathY);
            gr.DrawString(name, Font, brush, x / 2 + 5, y - 35);

            IntPtr ptr = pic.GetHicon();
            var c = new Cursor(ptr);
            return c;
        }
