C#中Imagelist控件

private void InitializeComponent()

           this.imageList1.Images.SetKeyName(0, "10000.png");

ImageList ImageList1 = new ImageList();
ImageList1.ImageSize = new Size(50,50);
//声明一个字符串,用来保存图片路径
string path;
for (int i = 0; i < 32; i++)
{
    if (i<10)
    {
        path = String.Concat("../../images/Bomb/1000", i.ToString(), ".png");
    }
    else
    {
        path = String.Concat("../../images/Bomb/100", i.ToString(), ".png");
    }
    imageList.Images.Add(Image.FromFile(path));
} 
用代码创建一个ImageList实例，规定图标大小50×50，接着使用ImageList.Images.Add方法加入Image对象，这边使用文件路径生成Image对象。
三、ImageList常用的方法大多在 ImageList.Images下
方法：

 ImageList.Images.Add：加入图像ImageList.Images.Clear: 清除图像ImageList.Images.Draw: 绘制指示的图像ImageList.Images.ContainsKey: 确定是否包含指定键的图像ImageList.Images.IndexOfKey：确定包含指定键的图像的序号ImageList.Images.RemoveAt：删除指定序号的图像ImageList.Images.RemoveByKey:删除指定键的图像ImageList.Images.SetKeyName:为指定序号的图像设置键名
属性：

 ImageList.Images.Count: 集合中包含的图像数ImageList.Images.Empty：集合中是否包含图像
