如何在pictureBox中显示资源文件中的ICO资源

Question

我在资源文件中导入了很多ICO图标文件，想根据条件在picturebox中显示不同的图形。但是在程序中如下代码，结果显示编译出错。请问高手，如何在picturebox中加载ICO资源文件。
            switch (i)
            {
                case 0:
                    pictureBox1.Image =newDraw.Properties.Resources.c;
                    break;
                case 1:
                    pictureBox1.Image = newDraw.Properties.Resources.c1;
                    break;
                case 2:
                    pictureBox1.Image = newDraw.Properties.Resources.c2;
                    break;
                case 3:
                    pictureBox1.Image = newDraw.Properties.Resources.c3;
                    break;
                    
                case 4:
                    pictureBox1.Image = newDraw.Properties.Resources.c4.ToBitmap;
                    break;
                case 5:
                    pictureBox1.Image = newDraw.Properties.Resources.c5.ToBitmap;
                    break;
                case 6:
                    pictureBox1.Image = newDraw.Properties.Resources.c6.ToBitmap;
                    break;
                case 7:
                    pictureBox1.Image = newDraw.Properties.Resources.c7.ToBitmap;
                    break;
                case 8:
                    pictureBox1.Image = newDraw.Properties.Resources.c8.ToBitmap;
                    break;
                case 9:
                    pictureBox1.Image = newDraw.Properties.Resources.c9.ToBitmap;
                    break;

Answer 1

ImageList ImageList = new ImageList();
ImageList.ImageSize = new Size(16,16);
ImageList.TransparentColor = Color.White;
ImageList.Images.Add(global::实例.Properties.Resources.a);
ImageList.Images.Add(global::实例.Properties.Resources.b);
pictureBox1.Image = ImageList.Images[1];

Answer 2

pictureBox1.Image = newDraw.Properties.Resources.c.ToBitmap();

Answer 3

pictureBox1.Image = newDraw.Properties.Resources.c.ToBitmap();
