C#中ImageList组件应用实例
ImageList组件
1．功能
ImageList组件用于存储图像，这些图像可由控件显示。图像列表能够为一致的单个图像目录编写代码。图1所示为ImageList组件。
图1 ImageList组件
2．属性
ImageList组件常用属性及说明如表1所示。
表1 ImageList组件常用属性及说明
下面详细介绍Images属性，此属性表示图像列表中包含图像的集合。
语法：
public ImageCollection Images { get; }
属性值：图像集合。
示例
Images属性的使用
本示例主要是通过Images属性为pictureBox1控件的Image属性赋值。
程序主要代码如下：
this.pictureBox1.Image = imageList1.Images[0];
this.pictureBox2.Image = imageList1.Images[1];
完整程序代码如下：
