如何在pictureBox中显示资源文件中的ICO资源

[sszzhh]

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;
case 10:
pictureBox1.Image = newDraw.Properties.Resources.c10.ToBitmap;
break;
}

错误 1 无法将类型“System.Drawing.Icon”隐式转换为“System.Drawing.Image” D:\project\newDraw\newDraw\FormTest.cs 89 40 newDraw

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];

[whowhen21]

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

[wxmayifei]

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

这样写也行，学习了！
newDraw是哪个的实例呢？
